station
External latch signal
Zero point return deceleration LS
Reverse drive prohibited when N-LS is open
Forward drive prohibited when P-LS is open
1Ry OFF with servo alarm
2Ry OFF with servo ready
Note 1. Maximum capacity of each output circuit is 50 mA and 30 VDC.
2. Signal output line
3. The 24 VDC power (I/O power) supply must be supplied by the user.
4. The power supply must be ON while the servo alarm (1Ry) remains OFF till the communication
connection (CONNECT command) is completed after the control power is turned ON.
