Onboard multiple preset speedsIt implements up to 16 speeds via the simple PLC function or combination of  terminal states
Onboard PIDIt realizes process-controlled closed loop control system easily.
Auto voltageIt can keep constant output voltage automatically when the mains voltage changes.
regulation (AVR)
Overvoltage/ Overcurrent stall controlThe current and voltage are limited automatically during the running process so as to avoid frequent tripping due to overvoltage/over current.
Torque limit and controlIt 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 functionsSupport for multiple PG cardSupport 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 throughThe load feedback energy compensates the voltage
reduction so that the AC drive can continue to run for a
short time.
Rapid current limitIt helps to avoid frequent over current faults of the AC drive.
High performanceControl of asynchronous motor and synchronous motor are
implemented through the high-performance current vector
control technology.
Timing controlTime range: 0.0-6500.0 minutes
Communication methodsMODBUS-RTU,PROFIBUS-DP,CAN
Protection modeMotor 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 outputInput terminal8 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 sourceDigital setting, analog voltage setting, analog current setting, pulse setting and serial communication port setting.
Auxiliary frequency sourceThere are ten auxiliary frequency sources.It can implement
fine tuning of auxiliary frequency and frequency synthesis.
Running command sourceOperation panel/Control terminals/Serial communication port
You can perform switchover between these sources in
various ways.
