request instruction
(D(P).CHGT2)
By executing the torque limit value change request
instruction (D(P).CHGT) in the PLC CPU, the torque limit
value of specified axis is changed to same value for both
of positive direction and negative direction.
By executing the torque limit value individual change
request instruction (D(P).CHGT2) in the PLC CPU, the
torque limit value of specified axis is changed to different
QDS value for positive direction and negative direction.

(3) Priority of torque limit value setting
When the multiple torque limit values are set on the same axis, the latest torque
limit value is valid. However, the setting of torque limit value set in the parameter
block or servo program is valid only if lower than the torque limit value set in the
Motion SFC program or Motion dedicated PLC instruction.
POINTS
When the torque limit value is set individually for positive direction and negative
direction in the Motion SFC program or Motion dedicated PLC instruction, only
either one of the positive direction or negative direction may become valid
depending on the setting value of servo program.
(4) Monitoring of torque limit status
(a) When using Q173DSCPU/Q172DSCPU
The torque limit value of each axis can be monitored with torque limit value
(D14+20n), and the positive/negative direction torque limit value can be
monitored by setting "Positive Direction Torque Limit Value Monitor Device"
and "Negative Direction Torque Limit Value Monitor Device" in the
expansion parameter.
The torque limit status of each axis can be also monitored with torque
limiting (M2416+20n).
(b) When using Q173DCPU(-S1)/Q172DCPU(-S1)
The positive direction torque limit value of each axis can be monitored with
the torque limit value (D14+20n).
The torque limit status of each axis can be also monitored with torque
limiting (M2416+20n).
