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 Servomotors and Servo Drives User's Manual (with Built-in EtherCAT Communications)
Probable cause
Inductive noise is occurring. Check to see if the drive control
There is an error in the
coupling of the mechanical
system and the
Servomotor.
The gain is wrong.
The load inertia is too large. • Check the load inertia.
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 coupling of
the mechanical system and the
Servomotor is misaligned.
−
• Check the Servomotor
rotation 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 between
the mechanical system and the
Servomotor.
Check if manual tuning can
achieve proper adjustment.
• Review the load inertia.
• Replace the Servomotor and
Servo Drive with proper
ones.
