Remedy
Set correctly.
Connect correctly.
1. Reduce the frequency of positioning.
2. Use the regenerative brake option of larger capacity.
3. Reduce the load.
Review the power supply.
Change the servo amplifier.
Change the servo amplifier or regenerative brake option.
Increase acceleration/deceleration time constant.
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.
Change the servomotor.
Correct the wiring.
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.
Connect correctly.
Change the cable.
Take noise suppression measures.
Connect correctly.
Set correctly.
Review the operation program.
Take noise suppression measures.
Change the AD75.
