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.
 Frequency source Digital setting, analog voltage setting, analog current setting, pulse setting and serial communication port setting.
 Auxiliary frequency source There are ten auxiliary frequency sources.It can implement fine tuning of auxiliary frequency and frequency synthesis.
 Running command source Operation panel/Control terminals/Serial communication port
