3. SIGNALS AND WIRING
3.1.6 Explanation of signals
For the servo amplifier signals, refer to the Servo Amplifier Instruction Manual of 22kW or less. This
section provides the converter unit signals.
For the I/O interfaces (symbols in I/O column in the table), refer to this section(2)

5
Common terminal for VDD. Isolated from LG.
Signal common
SE
3
Common for open collector output.
Connect to SG.
Shield

Plate
Connect one end of the shield cable.
Trouble
ALM
8
ALM-SG are disconnected when the protective circuit is activated
to shut off the base circuit at power-off.
They are connected when the status is normal at power-off.
DO-1
(2) Interface
Here are given the details of the output signal interface (DO-1: Refer to I/O Category in the above
table) given in (1) of this section. Refer to this section and connect the interfaces with the external
equipment.
A lamp, relay or photocoupler can be driven. (Permissible current: 40mA or less, inrush current:
100mA or less)
