1: The torque limit setting value or torque output setting value becomes effective at the PLC READY signal [Y0] rising edge
(however, after the servo turned ON.)
2: The torque limit setting value or torque output setting value becomes effective at the positioning start signal [Y10] rising edge,
and the torque limit value is updated.
3: The torque change value is cleared to "0" at the positioning start signal [Y10] rising edge.
4: The torque limit value is changed by the torque changed value.
5: When the new torque value is 0, a torque change is considered not to be carried out.
6: When the change value is exceeds the torque limit value, a torque change is considered not to be carried out.

[2] Precautions during control
(1) If a value besides "0" is set in the new torque value, the torque generated by
the servomotor will be limited by the setting value. To limit the torque with
the value set in "[Pr.17] Torque limit setting value" or "[Cd.101] Torque
output setting value", set "0" to the new torque value.
