Item
Z900 ac drive
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.
