B.5 Electric Potential Mode

Electric potential mode wiring diagram is as follows:

If set P0.11= 5, Electric potential mode is valid which use a button provide reference of

acceleration and deceleration commands.

Digital terminal S1 and S2 control crane running up and down. If inverter receives two

directions simultaneously, it will coast to stop; keypad will not display the fault information.

Acceleration and deceleration commands are connected to S4 and S5. If acceleration

contact closes after inverter starts accelerating toward 100% speed with certain slope. If

acceleration signal is removed before reaching 100%, inverter stops accelerating and runs

at current speed. If acceleration signal apply again, inverter accelerates according to

100% speed with certain slope again. Deceleration command is the same as acceleration

command.

If direction command is removed, inverter decelerates toward zero speed with certain

slope. If direction command is given again before inverter stops, it stops deceleration and

runs at current speed.

Electric potential mode parameter settings are as follows:
