[LD77MS4 operation example]
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 is 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
