Operating Functions
5-12 Torque Limit
Function
• The torque output by the Servomotor can be limited.
• This function is effective in the following cases:
• Pressing a moving part of a machine (such as a bending machine) against a workpiece with
constant force.
• Protecting the Servomotor and mechanical system from excessive force or torque.
• The torque limit method depends on the setting of Pn03.
Parameters Requiring Settings
Pn03 = 0
During operation, the torque is limited to the torque specified with the analog voltage or the torque
set in the parameter, whichever is smaller.
• If a positive voltage between 0 and 10 V is applied to PCL (forward torque limit input), the torque
will be limited for forward operation (+3 V/100%).
• If a negative voltage between 0 and −10 V is applied to NCL (reverse torque limit input), the
torque will be limited for reverse operation (−3 V/100%).
For the parameter setting, the maximum torque is limited by Pn5E for both forward and reverse
operation.
