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 or R88A-BAT02W) 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.
