8.3.2 Switching the Servomotor Rotation Direction
The rotation direction of the servomotor can be switched without changing the reference pulse to the
SERVOPACK or the reference voltage polarity.
This causes the travel direction (+, -) of the shaft reverse. The output signal polarity such as encoder pulse output
and analog monitor signal from the SERVOPACK does not change.
The standard setting for “forward rotation” is counterclockwise as viewed from the drive end.

(CW = Reverse)
The direction of P-OT and N-OT change. For Pn000 = n.†††0 (standard setting), counterclockwise is P-OT. For Pn000
= n.†††1 (Reverse Rotation Mode), clockwise is P-OT.
