13.2 Check Error Code
Action
• Correct the setting of the regenerative brake
option (servo parameter).
→Refer to subsection 11.2.1
• Correctly connect the built-in regenerative brake
resistor or regenerative brake option.
• High-duty operation or continuous regenerating
operation to exceed the permissible regenerative
power of the regenerative brake option.
- Reduce the frequency of positioning.
- Change the regenerative brake option to the
one with a larger capacity.
- Reduce the load.
• Review the power supply
• Change the servo amplifier or regenerative brake
option.
• When the acceleration/deceleration overshoots,
check the acceleration/deceleration time constant
in the fixed parameters.
• If the servo gain cannot be set to a proper value:
- Reduce the load inertia moment ratio (servo
parameter) of the servo motor.
→Refer to subsection 11.2.2
- Review the acceleration/deceleration time
constant.
• Change the servo motor.

• Correct the setting of the regenerative brake
option (servo parameter).
→Refer to subsection 11.2.1.
• Change the regenerative brake option leads.
• Correctly connect the regenerative brake option
leads.
• Replace the servo amplifier.
• For a wire break of the built-in regenerative brake
resistor, change the servo amplifier.
• For a wire break of the regenerative brake option,
change the regenerative brake option.
• Add the regenerative brake option or increase the
capacity.
• Review the power supply
• Correct the wiring.
• Connect after turning the control circuit power
supply of the servo amplifier OFF.
• Wipe off any dirt from the end surface.
• Change the cable.
