Parameterizing the function
Parameter
Description
P0700 = 2
Controls the motor using the digital inputs of the inverter
P0727 = 2
Three-wire control, method 1
P0701 = 1
The enable signal to power-up the motor is issued with digital input 0
Further options: The enable signal can be issued with any other digital input, e.g. with
digital input 3 via P0704 = 1
P0702 = 2
CW rotation is activated with digital input 1
Further options: CW rotation can be activated with any other digital input, e.g. with
digital input 3 via P0704 = 2
P0703 = 12
CCW rotation is activated with digital input 2
Further options: CCW rotation can be activated with any other digital input, e.g. with
digital input 3 via P0704 = 12
