Zero point return deceleration LS O V — 0 DEC
Reverse drive prohibited when N-LS is open
Forward drive prohibited when P-LS is open
1Ry turns OFF with Servo alarm
2Ry turns OFF with Servo ready
Note 1. Maximum capacity of each output circuit is 30 VDC and 50 mA.
2. Signal output line I represents twisted-pair wires.
3. The 24 VDC power supply (I/O power supply) must be supplied by the user.
4. The power supply must be ON while the servo alarm (lRy) remains OFF till the communication connection (CONNECT command)
is completed after the control power is turned ON.
5. SERVOPACK model SGDB-60 to -1E require a regenerative resistor (externally mounted option).
