Normal Torque Limit
Automatic Control during Origin Search
Connection with Servo Drive
This function turns ON/OFF the torque limit output to the Servo Drive from the PCU.
Turning ON/OFF the [Torque Limit Output] bit in the [Manual Operation Command Memory
Area] turns ON/OFF the torque limit output at the Servo Drive connector.
Torque limit by normal positioning, such as holding control, is based on ON/OFF control of the
torque limit output by a ladder program.
If you select [B: Proximity Rev Turn/ Holding Time], [C: Proximity Rev Turn/ Holding Origin
Input] or [D: No Origin Proximity Input/ Holding Origin Input] for Origin Search operation, the
torque limit output is controlled automatically.
Under automatic control of the torque limit output during Origin Search, the torque limit output
remains ON even after Origin Search completed (after the origin confirmation).
For details, refer to "Operation by 11: Proximity Reverse Turn and Holding Time Specified" on
page 4-30, "Operation by 12: Proximity Reverse Turn and Holding Origin Input Specified" on
page 4-30 and "Operation by 13: No Origin Proximity Input and Holding Origin Input Specified"
on page 4-31.
If the axis moves in the direction opposite to the origin input detection direction, the torque limit
output turns OFF.
If you perform origin compensation operation in the reverse direction against the origin input
detection direction, for example, the torque limit output turns OFF at the start of origin
compensation operation.
If you use the torque limit function, a torque limit switch input is necessary for the Servo Drive.
Change the Servo Drive setting so as to use the torque limit switch input below:
G5 Series
(R88D-KTx)
Even when the torque limit output of the Origin Search function is controlled automatically, you
can still turn ON/OFF the torque limit output. In this case, however, whether the signal is output is
determined based on the OR condition with the automatic control.
