(b) Position deviation error detection
Set [Pr. PE03] to "_ _ _ 2" to enable the position deviation error detection.

[Pr. PE03]
Comparing the servo motor-side feedback position (2)) and load-side feedback position (4)), if the
deviation is not less than the set value (1 kpulses to 20000 kpulses) of [Pr. PE07 Fully closed loop
control position deviation error detection level], the function generates [AL. 42.1 Servo control error
by position deviation] and stops. The initial value of [Pr. PE07] is 100 kpulses. Change the set value
as required.
(c) Detecting multiple deviation errors
When setting [Pr. PE03] as shown below, multiple deviation errors can be detected. For the error
detection method, refer to (2) (a), (b) in this section.
