Omron R88D-UA - User Manual

About this Manual:
This guide describes the installation and startup procedures of the Servo System so that it can
be efficiently put in actual operation in a short time.
This guide provides detailed descriptions of key points for efficiently starting up the Servo Sys-
tem as follows:
• Check the wiring by efficiently using the monitor function.
• Perform gain adjustments properly.
• Find the causes of alarms quickly and take the appropriate countermeasures.
• Take appropriate countermeasures for position deviation that might be caused by
noise.
This guide applies to the following OMRON products:
• OMNUC U Series
• OMNUC H Series
• OMNUC M Series
• OMNUC R Series
It is recommended that the following manuals be referred to when actually performing the work.
