ID 70099

Difference between command and feedback positions after controller release too big.

Description

The difference between the new command position value and the old actual value is greater than the permissible limit value when releasing the drive controller (see P-AXIS-00108).

When the controller release is set, the axis is given a new command value. If this command value differs from the actual value, an abrupt stimulation of the drive occurs. In order to limit the resulting axis motion, the control deviation with respect to a limit value (see P-AXIS-00108) is monitored. If the current difference between command and actual positions is bigger than the specified value when releasing the drive, the position difference is not extended.
