| 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 |
| Communication methods |
RS485 (MODBUS-RTU) |
| Protection mode |
Motor short-circuit detection at power-on, input/output phase loss protection, over current protection, overvoltage protection, under voltage protection, overheat protection and overload protection. |
| Input and output |
Input terminal |
6 digital input terminals, one of which supports up to 100 kHz high-speed pulse input. |
| 2 analog input terminals, one of which only supports 0–10 V voltage input and the other supports 0–10 V voltage input or 4–20 mA current input. |
