7 AUXILIARY AND APPLIED FUNCTIONS
7.3 Torque Limit Function
This function restricts the generating torque of the servomotor within the setting range.
If the torque required for control exceeds the torque limit value during positioning
control, it restricts with the setting torque limit value.
(1) Setting range of the torque limit value
It can be set within the range of 1 to 1000[%] of the rated torque.
(2) Setting method of torque limit value
Set the torque limit value is shown below.
(a) Setting in the parameter block (Refer to Section 4.3).
Set the torque limit value in the parameter block.
By setting the parameter block No. used in the servo program, it can be
restricted the generating torque of the servomotor within the specified torque
limit value for every positioning control.
(b) Setting in the servo program
By setting the torque limit value in the servo program, it can be restricted the
generating torque of the servomotor within the specified torque limit value at
the execution of the servo program.
(c) Setting in the Motion SFC program
By executing the torque limit value change request (CHGT) in the Motion
SFC program or operating control step, it can be set the generating torque of
the servomotor within the specified torque control value.
(Refer to the "Q173HCPU/Q172HCPU Motion controller (SV13/SV22)
Programming Manual (Motion SFC)" for details.
