Onboard multiple preset speeds |
It implements up to 16 speeds via the simple PLC function or combination of terminal states |
Onboard PID |
It realizes process-controlled closed loop control system easily. |
Auto voltage regulation (AVR) |
It can keep constant output voltage automatically when the mains voltage changes. |
Overvoltage/ Overcurrent stall control |
The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to overvoltage/over current. |
Torque limit and control |
It can limit the torque automatically and prevent frequent over current tripping during the running process. |
Power dip ride through |
The load feedback energy compensates the voltage reduction so that the AC drive can continue to run for a short time. |
Rapid current limit |
It helps to avoid frequent over current faults of the AC drive. |
High performance |
Control of asynchronous motor are implemented through the high-performance current vector control technology. |
Timing control |
Time range: 0.0–6500.0 minutes |
