1.3 Handling methods for alarms/warnings
Check/action method
Check the torque ripple with MR Configurator2.
If the torque ripple is vibrating, adjust the servo gain with the auto tuning. Set
the machine resonance suppression filter.
Measure the resonance frequency of the equipment and compare the value
with the setting value of the machine resonance suppression filter. If the
resonance frequency of the equipment and the value of the filter differs,
change the setting of the machine resonance suppression filter.
Replace the servo motor or linear encoder.
