Minor error120

Answer

Minor error 120 occurs in the following case:
The zero pass signal (M2406+20n) is OFF when the re-movement to the home position is performed by proximity dog, count, and limit switch combined methods, or when the home position return by data set method is started.
Turn the servo motor at least one revolution to pass the zero point.
Execute the home position return after that.
