Item Z900 Standard functions Multiple preset speeds It implements up to 16 speeds via the simple PLC function or by input(X) terminal states Built-in 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. Over-voltage/ Over-current stall control The 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 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 high-performance current vector control technology. Timing control Time range: 0.0-6500.0 minutes Communication methods RS485 Protection mode Motor 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 output Input terminal 6 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 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.
