reference unit
P
In fully-closed loop control, there is a tolerance between the reference unit corresponding to the
encoder feedback position and user reference unit corresponding to the grating ruler feedback
position. The tolerance is called hybrid-control deviation, specified by R0.05. If R0.05 exceeds the
setting of this parameter, the drive reports fault Er22-1.

rotations
P
This parameter specifies the condition for clearing the hybrid-control deviation. When the motor
rotation number reaches the specified one, the hybrid-control deviation is cleared. The value 0
indicates the hybrid-control deviation is not cleared.
