V/F separation
2 ways: full separation, semi-separation
Acceleration/deceleration
curves
Linear or S-curve acceleration/deceleration way.
Four kinds of acceleration/deceleration time
Acceleration/deceleration time range: 0.0~6500.0s
DC braking
DC braking frequency: 0.00Hz~maximum frequency; Braking time:
0.0s~36.0s braking action; Current value: 0.0%~100.0%
Inching control
Inching frequency range: 0.00Hz~50.00Hz;
Inching acceleration/deceleration time 0.0s~6500.0s
Simple PLC, multi-stage
velocity operation
Realize 16-stage velocity operation at most through built-in PLC or
control terminal
Built-in PID
Easy to realize process control, closed-loop control system
Automatic voltage regulation Keep constant output voltage automatically if any change of network
voltage
Overvoltage, overcurrent,
stalling control
Limit current/voltage automatically during operation, prevent frequent
tripping caused by over-current and over-voltage
Fast current-limiting function Reduce over-current fault, protect normal operation of convertor
Torque limit and control
“Nawy” character limit torque during operation,
prevent frequent overcurrent tripping, closed-loop
vector mode can realize torque control
