Reverse drive prohibited when N-LS is open
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.
5. SERVOPACK model SGDB-60 to -1E require a regenerative resistor (externally mounted option).
