[Setting data]
Setting data Description Data type of result
(S1)
Axis No. to which torque limit value change request
will be given
—
(S2) Positive direction torque limit value (0.1[%])
(S3) Negative direction torque limit value (0.1[%])
[Functions]
(1) The torque limit value of the axis specified with (S1) is changed to the positive
direction torque limit value specified with (S2) and negative direction torque limit
value specified with (S3).
The positive direction torque limit value restricts the forward rotation (CCW)
driving torque and reverse rotation (CW) regenerative torque of the servo motor,
and negative direction torque limit value restricts the reverse rotation (CW) driving
torque and forward rotation (CCW) regenerative torque of the servo motor.
(2) Any axis that has completed a servo startup can be changed in torque limit value
any time, independently of the status, starting, stopping, servo ON or servo OFF.
(3) When the CHGT2 instruction is executed to the mechanical system output module
in the virtual mode, set 300[%] as the torque limit value of output module. When
the torque limit value of output module is indirectly specified with a device, a minor
error (error code: 6260) will occur, and the individual change of torque limit value
is not executed.
(4) The axis No. that may be set at (S1) is within the following range.

(5) (S2) and (S3) cannot be omitted. When only either torque limit value is changed,
set "-1" as the setting data not to change.
