CHAPTER 4 PARAMETER
4-84
Extended Function Setting Parameter
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 (sequence input signal) turned off

Sudden controlled stop caused by forced stop (sequence input signal) turned off

Sudden controlled stop caused by ±OT (sequence input signal) turned off

Controlled stop caused by minor failure alarm (If PA2_62 is 4 or 5)
(5) Deviation holds selection at torque limit
This parameter is enabled under position control.
Position deviation is held with this function after a contact stop. Position deviation is held so that
the position deviation count does not reach the limit at the contact stop.
The function is enabled under the following conditions. (If PA2_57 is 0)
