Page 385 Setting items for home position return parameters
Start of the driver home position return method
Set "9001" in "[Cd.3] Positioning start No.", and start the axis.
The control mode of the servo amplifier is set to "Home mode".
If Zero speed is not ON ([Md.119] Servo status 2: b3 is not ON) at start for the MR-J5(W)-G, the home position return
operation does not start until Zero speed turns ON. Even in this case, "7: Home position return" is set in "[Md.26] Axis
operation status".
When the home position return starts/completes and the control mode of the servo amplifier does not change within 1 second,
the error "Control mode switching error" (error code: 1F04H) occurs.
Axis stop of the driver home position return method
When "[Cd.180] Axis stop" is turned ON during the home position return, the "HALT" signal is sent to the servo amplifier. If the
servo amplifier which does not support the "HALT" signal is used, the axis is not stopped by this signal. Use the forced stop
signal instead. Refer to the manual of the servo amplifier for support information on the HALT signal and forced stop signal.
The MR-J5(W)-G supports the HALT signal.
