6-1 Torque limit switching function
It is a function which changes a torque limit value by the direction of operation.
(1) Applicable range
□ This function can be applicable only when the following conditions are satisfied.
Conditions under which the torque limit switching function is activated
Control mode
• Position control, velocity control. *1)
Others
• Should be in servo-on condition
• Parameters except for controls are correctly set, assuring that the motor can operate normally.
*1) During torque controlling, the switching function is disabled and only Pr. 0.13 1st torque limit is enabled.
