Digital Brushless AC Servo Drive system - Ref. 1809 BCSD-57/116
4.3.2. Switching the Servomotor Rotation Direction
The rotation direction of the servomotor can be switched without changing the reference pulse to the
servodrive 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 servodrive does not change.
The standard setting for “forward rotation” is counterclockwise as viewed from the servomotor load end.

The direction of P-OT and N-OT change. For Pn001=b.0 (standard setting), counterclockwise is P-OT. For
Pn001=b.1 (reverse rotation mode), clockwise is P-OT.
