functionsMultiple preset speedsIt implements up to 16 speeds via the simple PLC function or by input(X) terminal statesBuilt-in PIDIt realizes process-controlled closed loop control system easily.Auto voltage
regulation (AVR)It can keep constant output voltage automatically when the mains voltage changes.Over-voltage/
Over-current stall
controlThe current and voltage are limited automatically during the running process so as to avoid frequent tripping due to
over-voltage/over-current.Torque limit and torque
controlIt can limit the torque automatically and prevent frequent over-current tripping during the running process.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 performancehigh-performance current vector
control technology.Timing controlTime range: 0.0-6500.0 minutesCommunication methodsRS485Protection modeMotor short-circuit detection at power-on, output phase loss protection, over-current protection, over-voltage
protection, under voltage protection, overheat protection and overload protection.Input and outputInput terminal6 digital input terminals, one of which supports up to 100 kHz high-speed pulse input.
1 analog input terminals, switchable between 0-10 V input and 4-20 mA 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.Output terminal1 digital output terminal
1 relay output terminal
1 analog output terminal :that supports 0-20 mA current output or 0-10 V voltage output
