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
It can keep constant output voltage automatically when the mains voltage changes.
regulation (AVR)
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.Torque control can be implemented in the CVC mode.
Individualized functions
Support for multiple PG card
Support for rotating transformer PG card,differential input PG card, UVW differential input PG card, resolver PG card and OC input PG card
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 and synchronous motor are
implemented through the high-performance current vector
control technology.
Timing control
Time range: 0.0-6500.0 minutes
Communication methods
MODBUS-RTU,PROFIBUS-DP,CAN
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.
