Emotron VSB Instruction Manual Chapter 1 Safety Precautions

1.2 Other Considerations

1.2.1 Input Power Supply

This series of drives are not applicable to applications out the range of operating voltage as set

forth in this manual. If necessary, please use booster to rise or drop the voltage to regulated

voltage range.

1.2.2 Surge Protection

This series of drives are furnished with surge suppressor that has certain resistance to lightning

induction. However, users in areas with frequent occurrence of lightning need to mount an

external surge suppressor in front of the drive power input side.

1.2.3 Operation of Contactor

As to the configuration of peripheral devices recommended by this manual, it is necessary to

mount a contactor between the power supply and this drive input side. Such a contactor should

not be used as a control device for start and stop of the drive, as frequent charging &

discharging shall reduce the service life of internal electrolytic capacitors.

When it is necessary to mount a contactor between the drive output and the motor, it

should be ensured the drive is in a non-output status before switch-on/switch-off of such a

contactor. Failure to comply may result in drive damage.

1.2.4 Output Filter

Since the drive output is PWM high frequency chopping voltage, mounting filter devices such

as an output filter and an output AC reactor between the motor and the drive shall effectively

reduce output noise, avoiding interference to other surrounding equipments.

If the length of cable between the drive and the motor exceeds 100m, an output AC reactor

is recommended to use with the purpose of preventing drive fault as a result of overcurrent

caused by excessive distributed capacitance. An output filter is optional depending on field

requirements.

Be sure not to mount phase-shifting capacitor or surge absorber at output side of the drive

since this may result in drive damage as a result of over-temperature.

1.2.5 Insulation of the motor

In view of the fact that the drive output is PWM high frequency chopping voltage accompanied

by higher harmonics, the noise, temperature rise and vibration of the motor is higher compared

with sinusoidal voltage. Particularly this debases motor insulation. Therefore, the motor should

be subjected to insulation inspection before initial use or reuse after being stored for a long

- 6 -

Emotron VSB Instruction Manual Chapter 1 Safety Precautions

period of time. The motor in regular service should also be subjected to regular insulation

inspection so as to avoid the drive damage as a result of motor insulation damage.

1.2.6 Derating

Due to the thin air in high-altitude areas, the radiating performance of the drive with forced air

cooling may degrade while the electrolyte of electrolytic capacitors is more volatile, which can

result in reduction in product life. Drive should be derated when used in an area at the altitude

above 1000 meters. It is recommended to derate 1% for every 100m when the altitude is above

1000 meters.

Emotron VSB Instruction Manual Chapter 3 Installation and wiring

3.7 Control Terminal Wiring

WARNING

 Only qualified personnel familiar with AC motor drives are allowed to implement wiring.

Failure to comply may result in equipment damage and/or personnel injury even death.

 Wiring should be in strict accordance with this manual, otherwise hazard of electric

shock or equipment damage exists.

 Make sure input power supply has been completely disconnected before wiring

operation. Failure to comply will result in personnel injury even death.

 All wiring operations and lines should comply with EMC and national and local industrial

safety regulations and/or electrical codes. The conductor diameter should

be in

accordance with recommendations of this manual. Otherwise, hazard of equipment

damage, fire, and/or personnel injury exists.

 Screws or bolts for terminal wiring must be screwed tightly.

 AC 220V signal is prohibited from connecting to other terminals than control terminals

RA, RB and RC.

ATTENTION

 Signal wires should to the best of possibility be away from main power lines. If this

cannot be ensured, vertical cross arrangement should be adopted, reducing EMI

interference to the signal wires as much as possible.

C3-04

AO gain

Range: -2.000 to 2.000

Factory default: 1.000

When users need to chang AO measurement range or correct the error of the meter, it can be

realized by setting of C3-03 and C3-04. If using factory default, 0~10V (or 0~20mA) of AO

corresponds to “0~maximun”. See table 6-4 for details. By expressing standard output of AO as

x, the adjusted AO1 output as y, the gain as k, and the offset as b (100% of offset corresponds

to 10V or 20mA), there is the equation: y=kx+b

Example:

C3-00 is set to 2: output frequency. Standard AO output: AO outputs 0V when output frequency

is 0, and outputs 10V when output frequency is the maximum frequency. If AO is requested to

output 2V when output frequency is 0Hz, and to output 8V when output frequency is the

maximum frequency.

There is: 2=k×0+b; 8=k×10+b. Through these two equations, we obtain: k = 0.6, b = 2V, i.e.

C3-03 is set to 20.0% while C3-04 is set to 0.600.

Emotron VSB Instruction Manual Chapter 6 Specification of Parameters

2: Rotating identification

To perform rotation identification, it is essential to disengage the motor from its load.

Identification is prohibited when motor is loaded. After d0-22 is set to 2 and confirmed, press

RUN to perform static identification, upon the completion of which, the motor would

accelerate to a fixed frequency in the set ramp-up time, maintaining a period of time, and

then stop by ramp down according to the set ramp down time. In this way, the identification

comes to an end, and d0-22 will be restored to 0. Parameters d0-07 - d0-14 have be

obtained after the successful completion of rotating identification. To perform rotating

identification, please set appropriate ramp-up and ramp-down time (i.e. Accel/Decel time. If

overcurrent or overvoltage fault occurs during identification, please prolong Accel/Decel time

accordingly.

 ATTENTION:

 Please make sure the motor is in a stationary state before the identification, or

parameter identification cannot be performed normally.

 Keypad displays "TUNE" and RUN indicator light is on during identification. RUN

indicator light is off upon the completion of parameter identification.

 Once parameter identification fails, the fault code "tUN" shall be displayed.

d1-09 Torque boost Range: 0.0% - 30.0%

Factory default:

0.0%

Under V/f pattern, output voltage at low frequency can be compensated by this parameter,

improving the torque output. 0.0% corresponds to automatic torque boost, and drive output

voltage is automatically compensated via detection of load current. Automatic torque boost is

valid only for linear V/f pattern.

100% of torque boost corresponds to rated voltage of motor. A non-zero value means the

output voltage rises on the basis of V/f curve and this takes effect at parameter values 0 - 6 of

d1-00. It is suggested this parameter value be gradually increased from zero until the starting

requirement is met. Boost value is not suggested to be set to a relatively big one, as it is likely

to bring about a bigger drive current and higher motor temperature.

Torque boost diagram is shown in Fig. 6-32:

d1-10 Slip compensation gain Range: 0.0% - 400.0%

Factory default:

100.0%

Used under V/f control. When the motor is driving an electric-driven load, motor speed drops

with the increase of load. When the motor is driving a power generating load, motor speed will

increase with the increase of load. Appropriate slip compensation gain can maintain constant

motor speed when the motor load is changing.

To ensure the performance of slip compensation gain, setting motor rated speed d0-06 is

essential. The difference between d0-06 and the motor running speed without load is the rated

slip. Through real-time detection of motor load, slip compensation automatically adjusts the

drive output frequency on the basis of rated slip and motor load, reducing the impact of

changing load on motor speed.

d1-12

Current limitation source

Range: 0 - 2

Factory default: 1

0: Disabled

1: Set by d1-13

2: Set by AI

When a non-zero value is set by d1-12, the current limitation is enabled. When output

current rises dramatically because of sharp change of load, instant adjustment of output

frequency will keep the output frequency below the set limitation. When the load is reduced,

output frequency will recover promptly. If the setting speed or motor load change dramatically,

this function can effectively reduce over-current fault.

When current limitation is enabled, the output frequency at constant speed may change at

times and the Accel/Decel time may probably be automatically prolonged. Therefore, this

function should not be used where output frequency or Accel/Decel time is not allowed to

change.

d1-13

Digital setting of current

limit value

Range: 20.0% - 200.0%

Factory default:

160.0%

When d1-12 is set to "1: set by d1-13", the drive keeps output current less than this current limit

value through instantaneous adjustment of output frequency. 100% current limit value

corresponds to rated current of the drive. If this parameter value is set to a relatively big one, it

will increase the chances of over-current. If this parameter value is set to a relatively small one,

it will affect the loaded capability of the drive.

During no-load or light-load application, load current is detected so as to appropriately reduce

output voltage, reducing the copper loss and iron loss of motor with the purpose of energy

saving. The larger the energy-saving percentage is, the better the energy-saving effect will be,

but the response will be slower. This parameter is applicable to loads such as fan and pump or

light-load for a long time. Where rapid change is required, this parameter is suggested to be

Under sensor-less vector control (SVC), motor speed is kept at set value by automatic speed

regulator (ASR). ASR parameters should be set in d2-01 - d2-06.

The proportional gain Kp and integration time Ti of ASR can be set through d2-01 - d2-04

so as to change the speed response characteristic under SVC.

Increment of proportional gain Kp can bring in fast response of the system. However,

bigger Kp value will bring about larger system oscillation.

Reduction of integration time Ti can also quicken response time, but small Ti value will

result in big system overshooting and may easily bring about oscillation.

Principle for adjustment of proportional gain Kp and integration time Ti: proportional gain

Kp is usually adjusted prior, maximizing Kp at the premise of ensuring the system is subject to

no oscillation, and then adjust integration time Ti to provide the system with both instant

d2-01 - d2-02 are the proportional gain and integration time of the drive at high speed.

d2-03 - d2-04 are the proportional gain and integration time of the drive at low speed.

Distinction between high speed and low speed is determined by d2-05 - d2-06. The

diagram is as shown in Fig. 6-35.

Fig. 6-35

ASR parameters are normally adjusted in the following order: select appropriate switching

frequency. Adjust proportional gain d2 -01 and integration time d2-02 at high speed, ensuring

the system has no oscillation and meets the requirements of dynamic response characteristics.

Adjust proportional gain d2-03 and integration time d2-04 at low speed, ensuring there is no

oscillation at low speed and requirements of dynamic response characteristics are met.

 ATTENTION:

Inappropriate parameters of Kp, Ti may bring about overcurrent or overvoltage faults.

Usually, fine adjustment should be performed close to factory default parameter.

Emotron VSB Instruction Manual Chapter 6 Specification of Parameters

Process PID is provided with two groups of proportion, integral and differential parameters set

by F0-14. F0-08~F0-10 are the first group of parameters.

Proportional gain Kp: dynamic response of the system can be quickened by increasing

proportional gain Kp. However, excessive Kp value would bring about system oscillation. Only

proportional gain control cannot eliminate steady state error.

Integration time: dynamic response of the system can be quickened by reducing

integration time Ti. However, excessively small Ti value would result in serious system

overshooting and may easily bring about oscillation. Integral control can be used to eliminate

steady state error but is unable to control sharp changes.

Differential time Td: it can predict the change trend of offset and thus can rapidly respond

to the change, improving dynamic performance. However, this is vulnerable to interference.

Please use differential control with caution.

F0-14

PID parameter switchover

Range: 0 - 2

Factory default: 0

Process PID is provided with two groups of proportional, integral and differential parameters,

which is set by this parameter.

0: No switch, determined by parameters Kp1, Ti1 and Td1

Always determined by Kp1, Ti1 and Td1 set at F0-08 - F0-10.

1: Auto switched on the basis of input offset

When the offset between setting and feedback is less than the set value of F0-15, PID

adjustment is determined by Kp1, Ti1 and Td1. When the offset between setting and

feedback is bigger than the set value of F0-15, PID adjustment is determined by Kp2, Ti2 and

Td2 set at F0-11 - F0-13.

2: Switched by terminal

When digital input terminal "PID parameters switch" is O FF, it is determined by Kp1, Ti1 and

Td1. When "PID parameters switch" is ON, it is determined by Kp2, Ti2 and Td2

F0-15

parameters.

When the offset between setting and feedback is less than this set value, it is determined

by Kp1, Ti1 and Td1.

When the offset between setting and feedback is bigger than this set value, it is

determined by Kp2, Ti2 and Td2.

F0-16 Sampling period T Range: 0.006s - 50.000s

Factory default:

0.008s

Sampling period aims at feedback. PID controller performs the sampling and compute once in

each sampling period. The longer the sampling period T is, the slower the response time will

be.

F0-17

PID offset limit

Range: 0.0% - 100.0%

Factory default:

0.0%

If the offset between PID feedback and setting is more than this set value, PID regulator will

implement regulation. If the offset between PID feedback and setting is less than this set value,

PID will stop the regulation and the PID controller output will be kept unchanged. This function

can improve the stability of PID performance.

F0-18 PID differential limit Range: 0.0% - 100.0%

Factory default:

0.5%

Sets differential output limit of PID control.

F0-19 PID initial value Range: 0.0% - 100.0%

Factory default:

0.0%

F0-20

Holding time of PID initial

value

Range: 0.0s - 3600.0s

Factory default:

0.0s

PID does not make adjustment when the drive starts its running, but outputs the value set by

F0-19 and maintains the holding time set by F0-20, then starts PID adjustment. When F0-20 is

set to 0, PID initial value is disabled. This function makes PID adjustment get into stable status

fast.
