Checking method Remedy
102 252 402 Set correctly.
Connect correctly.
Call the status display and check the
regenerative load ratio.
1. Reduce the frequency of positioning.
2. Use the regenerative brake option of larger capacity.
3. Reduce the load.
Review the power supply.
1) The regenerative brake option has
overheated abnormally.
2) Error occurs even after removal of the built-
in regenerative brake resistor or
regenerative brake option.
Change the servo amplifier.
Change the servo amplifier or regenerative brake option.
1. Change the servo amplifier or cooling fan.
2. Reduce ambient temperature.
Set command pulses correctly.
Increase acceleration/deceleration time constant.
112 252 402
1. Re-set servo gain to proper value.
2. If servo gain cannot be set to proper value:
1) Reduce " Pr.112 Load inertia ratio" (load inertia
moment ratio); or
2) Reexamine acceleration/deceleration time constant.

Set correctly.
Change the servomotor.
Correct the wiring.
Error code 2032 occurs if power is switched
ON after U, V and W are disconnected.
Change the servo amplifier.
Correct the wiring.
Take noise suppression measures.
1. Change lead.
2. Connect correctly.
Change the servo amplifier.
1. For wire breakage of built-in regenerative brake
resistor, change servo amplifier.
2. For wire breakage of regenerative brake option, change
regenerative brake option.
Add regenerative brake option or increase capacity.
Review the power supply.
