· Multiple Built-in Pre-set Speeds:
Realizes up to 16 speeds using simple PLC function or through input terminal states (X)
· Built-in PID Controller:
Easily implements closed-loop control system, process controlled.
· Automatic Voltage Regulation (AVR):
Can automatically maintain a constant output voltage when the power supply voltage changes.
· Overvoltage/Overcurrent Stop Control:
Current and voltage are automatically limited during operation to avoid frequent tripping due to
overvoltage/overcurrent.
· Torque Limiting and Control:
It can automatically limit torque and prevent frequent tripping due to overcurrent during operation.
· Instant Stop Does Not Halt:
Load feedback energy compensates for voltage drop, allowing the AC drive to continue operating for a short time.
· Fast Current Limiting:
This helps to avoid frequent overcurrent overloads of the AC drive.
