7.12.3.7 Angular correction

An angle deviation between master and slave can be generated or eliminated in synchronous operation with

parameter PS.04.

With the positive edge of the input selected in parameter PS.03 "shift. slave input selection", a positive adjust-

ment is triggered.

The value of PS.04 is added to the master position, i.e.,:

ru.56 "set position" (corrected) = ru56 "set position" + PS.04

A negative adjustment is triggered with the positive edge of the input selected in parameter PS.10 "shift slave

inv. input selection".

The value of PS.04 is subtracted from the master position, i.e.,:

ru.56 "set position" (corrected) = ru.56 set position – PS.04

The value of PS.04 can be positive or negative.

The adjustment is always made with the synchronisation via ramps (see item 7.12.3.5.4) to avoid torque sur-

ges in the drive. The treatment of the switching condition "drive running synchronously" corresponds to the

behaviour during initial synchronisation with ramps.

The angle adjustment can, e.g., be used to align master and slave after the approach to reference point in the

inching mode.
