Safety information and precautions
General functions and descriptions of frequency convertor:
Abundant voltage classes: support three voltage classes, namely single-phase 220V, three-phase
1）
220Vand three-phase 380V.
Abundant control mode: apart from vector control of velocity sensor, sensorless vector
2）
control and V/F control, support V/F separation control.
Abundant field bus: support Modbus-RTU and CANlink field bus.
3）
Abundant encoder types: support difference encoder, open collector encoder and rotary
4）
transformer, etc.
Brand-new sensorless vector control algorithm
5）
Brand-new SVC creates better low-velocity stability, stronger low-frequency load capacity, and
supports torque control of SVC.
Powerful background software: uploading, downloading parameters, real-time oscilloscope can be
6）
realized on background software.
Functions
Overheat protection of motor After choosing PC1 expansion card, AI3 can receive temperature sensor
Fast current limiting
Dual motor switch
Restore user parameters
Accurate AIAO
Show customized parameters Users can customize function parameters to be displayed
Show altered parameters
Optional fault handing ways Users can select action modes of convertor after confirming certain faults:
PID parameter switch
PID feedback loss detection
DIDO positive/negative logic Users can set positive/negative logic of DIDO
DIDO response delay
Run under instantaneous stop Frequency convertor continues running within short time if instantaneous power
Timing operation
Opening for inspection:
When opening the box, please carefully confirm if the nameplate model and rated value of frequency
convertor are consistent with order. The package contains ordered machine, qualification certificate,
operation manual and warranty bill.
If any damage during transportation or certain omission, please contact with our company or supplier.
Specification of high-performance vector convertor
Introduction
input of motor (PT100 , PT1000) to realize overheat protection
Avoid over-current fault of frequency convertor
Two sets of motor parameters can realize dual motor switch
Users can save or restore own parameter settings
After factory calibration (or spot calibration), AIAO accuracy can be<20mv
User can view function parameters after modification
free halting, deceleration halting, continual operation. The users can also
select frequency for continual operation.
Two sets of PID parameters can switch by terminal or based on deviation
PID feedback loss detection value realizes protection during PID operation
Users can set response delay time of DIDO
outage or voltage decrease
Support timing operation for 6,500 minutes at most
