· Multiple Built-in Pre-set Speeds:
Realizes up to 16 speeds using a simple PLC function or through input terminal states (X)
· Built-in PID Controller:
Easily implements a closed-loop control system, driven by the process.
· Automatic Voltage Regulation (AVR):
Can automatically maintain constant output voltage as the supply voltage changes.
· Overvoltage/Overcurrent Stop Control:
Current and voltage are automatically limited during operation to avoid frequent trips due to
overvoltage/overcurrent.
· Torque Limiting and Control:
It can automatically limit torque and prevent frequent trips due to current overload during operation.
· Instant Stop Does Not Halt:
Feedback energy from the load compensates for voltage drop so that the AC drive can continue to operate for a short time.
