Resetting the absolute position loss alarm
Be sure to set the home position again after resetting the absolute position loss alarm.
• How to reset
1.
Turn the ALM-RST input to ON and then OFF to reset the alarm.
2.
Perform a return-to-home operation using an external controller.
3.
Set the home position again with the P-PRESET input.
Note
• Even after resetting the alarm, the alarm status will continue until the home position is
set again.
• Resetting the absolute position loss alarm will reset the current position to zero. As a
result, performing a positioning operation before the home position is set may cause the
motor to move the equipment abruptly. Always set the home position first.
