
Deviation clear
The difference between the command position (pulse input) and feedback position (present
motor position) is the deviation.
Issue a deviation clear signal to zero the internal deviation. The command position becomes the
same as the feedback position.
Deviation clear is always effective and active even during rotation.
Either edge or level can be selected with parameter PA3_36 to switch the input format of the
deviation clear signal.
Because the deviation is forcibly zeroed, the motor is stopped.
To perform homing and interrupt positioning, select the extension mode. For details, refer to the
following pages.

The single-shot output is forcibly turned off if the zero deviation signal is turned off.
