CAUTION
• For the stroke limit wiring, always use negative logic (normally closed contact). Using the positive logic (normally open contact) may cause serious accidents.
• The input signal of the servo amplifier is always turned OFF when the communication with the servo amplifier is disconnected. If using the state of the
external signal of the disconnected axis ([St.1071] External signals FLS (R: M32411+32n/Q: M2411+20n) / [St.1072] External signals RLS (R: M32412+32n/
Q: M2412+20n) / [St.1074] External signals DOG/CHANGE (R: M32414+32n/Q: M2414+20n)) as the external signal of another axis that is not disconnected,
design the system so that the machine will not go into a dangerous state due to the connection state of the servo amplifier.
Precision
Set the precision when the DOG signal is used for the count method home position return or the speed-position switching
control.

Details
The upper stroke limit is detected, and "operation of direction that the feed current value increase" cannot be executed.
The lower stroke limit is detected, and "operation of direction that the feed current value decrease" cannot be
executed.
The stop signal is detected, and an operation stops.
The proximity dog/speed-position switching signal is detected, and the home position return operation and speed-
position control switching is executed.
