
Torque limit under torque control
The limit [2] is always enabled.

Deviation hold selection at torque limit
Use deviation hold selection at torque limit (PA2_59) under position control to select the torque
limit for retaining the deviation amount.
 Parameter setting
To assign the torque limit signal to a sequence input terminal, specify the corresponding value
("19" or "20") to the input terminal function setting parameter.
If the torque limit signal is not assigned to the sequence input terminal, the settings of PA1_27
(forward rotation torque limit) and PA1_28 (reverse rotation torque limit) are always enabled.

Relevant description
(1) Torque limit detection signal
This signal is turned on while the output torque of the servomotor is equal to or larger than the
torque limit.
The torque limit detection output is enabled in all control modes.
To assign the torque limit detection to a sequence output terminal, specify the corresponding
value ("26") to the output terminal function setting parameter.
