Note 1. If using the operation keys on the front panel, press and hold the DATA Key for one second or

longer.

Note 2. Refer to 4-3-1 Operation Details for details of operations.

Reverse rotation

Forward rotation

Seen from the Servomotor output shaft, counterclockwise

(CCW) is forward rotation, and clockwise (CW) is reverse rota-

tion.

Forward/reverse Servomotor rotation

If the direction of Servomotor rotation and the speed feedback monitor symbols do not agree, the

Encoder Cable may be incorrectly wired. Check the conduction for each cable.

• If there is an error, refer to Chapter 5 Troubleshooting and take the necessary countermeasures.

4-2-2 Absolute Encoder Setup and Battery Changes

You must set up the absolute encoder if using a Servomotor with an absolute encoder.

Perform the setup if connecting a Battery Unit (R88A-BAT01W) to an absolute encoder

for the first time, or when setting the mechanical rotation data to 0 for a trial operation.

H Absolute Encoder Setup Procedure

• Be sure to follow this procedure carefully. Any mistakes in carrying out this procedure could result in

faulty operation.
