■Torque deviation error detection
Set [Pr. PL04] to "_ _ _ 4" to enable the torque deviation error detection.
[Pr. PL04]

Torque deviation error detection enabled
When you compare the command torque ( 5)) and the feedback torque ( 6)) in "Outline of servo control error detection
function", if the deviation is more than the value of [Pr. PL07 Torque/thrust deviation error detection level] (1% to 1000%), [AL.
42.3 Servo control error by torque/thrust deviation] will occur and the direct drive motor will stop. The initial value of this
detection level is 100%. Replace the set value as required.
For "Outline of servo control error detection function", refer to the following.

■Detecting multiple deviation errors
When setting [Pr. PL04] as shown below, multiple deviation errors can be detected. For the error detection methods, refer to
the following.
