Omron R88D-KN series User Manual page 397

Symptom
Vibration is occurring at
the same frequency as
the power supply.
The position is
misaligned. (Position
misalignment occurs
without an error being
output.)
G5 Series AC Servo Drives With Built-in EtherCAT Communications, Linear Motor Type
Probable cause
Inductive noise is occurring. Check to see if the drive control
The coupling of the
mechanical system is
insufficient.
The gain is wrong.
The load mass is too large.
12 Troubleshooting and Maintenance
Items to check
signal lines are too long.
Check to see if the control
signal lines and power supply
lines are bound together.
Check to see if the mechanical
system is misaligned.

• Check the load mass.
• Check the motor speed.
• The dynamic brake
resistance is disconnected.
Measures
Shorten the control signal lines.
• Separate control signal lines
from power supply lines.
• Use a low-impedance power
supply for control signals.
Correct the coupling of the
mechanical system.
Check if manual tuning can
achieve proper adjustment.
• Review the load mass.
• Replace the motor and Servo
Drive with proper ones.
