(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 motor. The initial value of [Pr. PE07] is 100 kpulses. Change the 
set value as necessary. 
 
(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.
