RVRSE (#0) The signal direction for the separate detector is:
0: Not reversed.
1: Reversed.
When there is a large torsion between the motor and separate detector,
this alarm may be issued when an abrupt acceleration/deceleration is
performed. In such a case, change the detection level.

RNLV (#1) Change of the feedback mismatch alarm detection level
1: To be detected at 1000 rpm or more
0: To be detected at 600 rpm or more
Action 2: This alarm is issued when the difference between the motor
position and the position of the separate detector becomes
larger than the excessive semi-closed loop error level.
Check that the dual position feedback conversion
coefficient is set correctly. If the setting is correct, increase
the alarm level. If the alarm is still issued after the level is
changed, check the scale connection direction.

[Setting] Detection unit. When 0 is set, detection does not take place.
Action 3: The current offset (equivalent to the current value in the
emergency stop state) of the current detector becomes too
large. If the alarm is issued again after the power is turned
on and off, the current detector is determined to be abnormal.
For the i Series, replace the control board of the amplifier.
For series other than the i Series, replace the servo-related
module in the CNC.
