Main Control
Functions
Jogging control
Jogging frequency range: 0.00Hz~max output frequency,
jog Acceleration/down time 0.0s~3600.0s.
Easy PLC,
multi-stage speed
run
Via built-in PLC or control terminal can realize max 16
stage speed run.
Built-in PID
Can realize process control conveniently.
Auto-adjustment
of the voltage
Can keep the output voltage constant automatically when
the grid voltage changed.
Dynamic over
voltage
suppression
Auto suppress energy feedback value while run
frequency changes, prevent bus over current tripping off.
Oscillation
suppression
Optimize V/F oscillation arithmetic, realize V/F steady
operation.
Individual
Function
Power dip ride
through
It ensures that the AC drive continues to run for a short
time when an instantaneous power failure or sudden
voltage reduction occurs.
Timing control
Timing control function: setting time range:
0min-65535min.
Multi-motor
switchover
Two motors can be switched over via two groups of motor
parameters.
Support extension
Support multi-function I/O extension card
Operation
Running
command source
