Operating Functions
5-8 Torque Limit
Œ
This function limits the output torque of the Servomotor.
Œ
This function is effective in the following cases:
Pressing a moving part of a machine (such as a bending machine) against a workpiece with a
constant force.
Protecting the Servomotor and mechanical system from excessive force or torque.
Œ
The Warning Output Selection (Pn09) can be set to output an alarm to the Warning Output
(WARN) when the torque limit function is enabled.
Œ
Two torque limits can be set and you can switch between them. To switch the torque limit setting,
enable the Torque Limit Switch Input (TLSEL) in the Zero Speed Designation/Torque Limit Switch
(Pn06).
Parameters Requiring Setting
*1. Values exceeding the default setting cannot be set. The default setting depends on the combination of the
Servomotor and Servo Drive.
*2. The Overspeed Detection Level Setting (Pn70) will function only when torque limit switching function is enabled.
Related Parameters
The following parameters must be set to use torque limit switching function.
*1. Values exceeding the default setting cannot be set. The default setting depends on the combination of Servomotor
and Servo Drive.
*2. The No. 2 Overspeed Detection Level Setting (Pn73) will function only when torque limit switching function is
enabled.
