9.6.2 Switching the Linear Servomotor Movement Direction
The movement direction of the linear servomotor can be switched without changing the reference pulse to the
SERVOPACK or the reference voltage polarity.
This causes the travel direction (+, -) of the motor to 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 movement” is the linear scale counting up direction.

n.†††1 Reverse
Direction Mode
(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 Direction Mode), clockwise is P-OT.
