Operating the converter without position controller
Converter factory setting
In the factory setting of the converter, the basic positioner supplies the setpoint for the speed
controller. Although other sources for the setpoint are available in the converter, they are
however locked.

Operating the converter without position controller
If you want to always operate the converter without the position control, you must inhibit the
position controller and enable another source for the setpoint.
Procedure:
●
Inhibit the position controller.
Set parameter p2550 = 0, e.g. using the STARTER "Position controller" screen.
●
Enable the setpoint.
Set parameter p1142 = 1, e.g. using the STARTER "Ramp-function generator" screen.
●
Delete the encoder assignment of the position controller.
Set parameter p2502 = 0, e.g. using the expert list in STARTER.
●
If disturbing alarms occur in operation, which refer to the encoder, then you can suppress
these. See also the section: Alarms, faults and system messages (Page 319).
