[AL. 042.9_Fully closed loop control error by speed deviation]
Cause
1.
The settings of the load-side encoder
resolution differ from the setting value.
2.
The mounting direction of the load-side
encoder is incorrect.
3.
The setting value of the speed deviation error
detection level is too low.

Check/action method
Check the settings of [Pr. PE04 Fully closed loop control - Feedback pulse
electronic gear 1 - Numerator] and [Pr. PE05 Fully closed loop control -
Feedback pulse electronic gear 1 - Denominator].
Check the mounting direction of the load-side encoder.
Change the setting of "Encoder pulse count polarity selection" as required.
[A]: [Pr. PC45.0 Encoder pulse count polarity selection]
[G] [WG]: [Pr. PC27.0 Encoder pulse count polarity selection]
Refer to "Checking position data of load-side encoder" in the following manual.
MR-J5 User's Manual (Hardware)
Calculate the motor-side/load-side speed deviation.
If the deviation is too large, review the mechanism of the equipment or the
operation status. Review the setting of [Pr. PE03 Fully closed loop control error
- Detection function selection] or [Pr. PE06 Fully closed loop control - Speed
deviation error detection level] as required.
