Control Function

Start torque compensation without weight sensor(only sin/cos encoders are viable)

Start torque compensation with weight sensor(weight sensor is necessary)

Auto-tuning(rotation, synchronous motors identify the initial magnetic pole angle in static state(sin/cos encoders)

Function of contacting brake control and output contactor control

Logic of elevator enable, can make the elevator running safer

Force slowdown running, overhaul running, emergency running

Energy saving running(RBU is necessary)

DC braking while starting and stopping

Multi-step speed control(8 steps speed can be set)

Digital, analog, communication, multi-step speed and speed tracking and start

FDT output for frequency reaches the setting value
