CHAPTER 4 PARAMETER
4-86
Extended Function Setting Parameters
4
(4) Third torque limit
This parameter is enabled under position or speed control.
The reference value of this parameter becomes the torque limit under the following conditions.

Sudden controlled stop caused by servo-on (S-ON) turned off

Sudden controlled stop caused by forced stop (ENG) turned off

Sudden controlled stop caused by ±Overtravel (±OT) turned off

Controlled stop caused by minor failure alarm (If PA2_62 is 4 or 5 or 20
□□
)
(5) Deviation holds selection at torque limit
This parameter is enabled under position control.
If a motion is stopped at a dead stop, position deviation is held with this function. Position deviation
is held so that the position deviation count does not reach the limit at the dead stop.
The function is enabled under the following conditions (when PA2_57=0).
