(2) Control precautions
• If a value besides "0" is set in the "[Cd.22] New torque value", the torque generated by the servomotor will be
limited by that value. To limit the torque with the value set in " Pr.17 Torque limit setting value", set the
"[Cd.22] New torque value" to "0".
• The "[Cd.22] New torque value" is validated when written to the LD75. Note that it is not validated from the
time the power supply is turned ON to the time the PLC READY signal [Y0] is turned ON.
• If the setting value is outside the setting range, the axis warning "Outside new torque value range" (warning
code: 113) will occur and the torque will not be changed.
• If the time to hold the new torque value is not more than 100ms, a torque change may not be executed.
(3) Setting method
To use the "torque change function", write the data shown in the following table to the LD75 using the program.
The set details are validated when written to the LD75.
Refer to  Page 211, Section 5.7 for the information on detail settings.
