(4) Setting the torque limit function
(a) To use the "torque limit function", set the "torque limit value" in the axis
control data or parameters indicated in the following table, and write them to
the AD75.
The data set to the axis control data is validated at the rising edge (OFF to
ON) of the PLC READY signal (Y1D) and at a start of the corresponding
control.
The data set to the parameters are validated at the rising edge (OFF to ON)
of the PLC READY signal (Y1D).
Setting
value
Set the torque limit value to be output by the
servomotor in %.
Set the torque limit value as a percentage.
Set the torque limit value after the " Pr.49 Creep
speed" is reached. Set as a percentage.
(b) The "torque limit value" set in the AD75 is transferred to the servo amplifier
at a start of the corresponding control to limit the torque.
REMARK
•
Parameters are set for each axis.
•
It is recommended that the parameters be set whenever possible with the AD75
software package. Execution by sequence program uses many sequence
programs and devices. The execution becomes complicated, and the scan times
will increase.
