(b) Speed deviation error detection
Set parameter No.PS04 to " 1" to enable the speed deviation error detection.

Parameter No.PS04
When you compare the model feedback position ( 3)) and the feedback position ( 4)) in figure 14.1, if
the deviation is more than the value of parameter No.PS06 (Servo control speed deviation error
detection level) (1 rev to 2000 rev), the alarm (Servo control error 42. ) will occur and the motor will
stop. The default value of parameter No.PS06 is 100r/min. Change the set value as required.
(c) Torque deviation error detection
Set parameter No.PS04 to " 4" to enable the torque deviation error detection.

Parameter No.PS04
Torque deviation
error detection valid
When you compare the command torque ( 5)) and the feedback torque ( 6)) in figure 14.1, if the
deviation is more than the value of parameter No.PS07 (Servo control torque deviation error detection
level) (1 to 1000 ), the alarm (Servo control error 42. ) will occur and the motor will stop. The
default value of parameter No.PS05 is 100 . Change the set value as required.
(d) Detecting multiple deviation errors
When parameter No.PS04 is set as follows, multiple deviation errors can be detected. For the error
detection methods, refer to (1) (a), (b), and (c) of this section.
