· Multiple Built-in Pre-set Speeds:
Up to 16 speeds can be realized via simple PLC function or 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 a constant output voltage while the supply voltage varies.
· 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:
The feedback energy from the load compensates for voltage drop, allowing the AC drive to continue operating for a short time.
· Fast Current Limiting:
This helps avoid frequent overloads of the AC drive.
· High Performance:
Asynchronous motor control is achieved using high-performance current vector control technology.
· Time Control:
Time range: 0.0–6500.0 minutes
· RS485
