Checking method Remedy
Connect correctly.
Change the cable.
Connect correctly.
Change the servo amplifier.
Refer to section "5.2.10
Servo parameters for MR-
J2S-B".
Set the parameter value to within the setting range.
Change the servo amplifier.
Review the operation method.
1. Change the servo amplifier or cooling fan.
2. Reduce the ambient temperature.
Review environment so that ambient temperature is 0 to
40°C.
1. Reduce load.
2. Review operation pattern.
3. Use servomotor that provides larger output.
Change servomotor.
1. Reduce load.
2. Review operation pattern.
3. Use servomotor that provides larger output.
Servo response setting
109 259 409
1. Repeat acceleration/deceleration to execute auto
tuning.
2. Change " Pr.109 Servo response setting".
3. Set auto tuning to OFF and make gain adjustment
manually.
1. Review operation pattern.
2. Install limit switches.
Connect correctly.
When the servomotor shaft is rotated slowly
with the servo OFF, the cumulative feedback
pulses should vary in proportion to the rotary
angle. (If the indication skips or returns
midway, the encoder is faulty.)
Change the servomotor.
1. Review operation pattern.
2. Install limit switches.
