Terminal function description
Common terminal for the contact input terminal (sink logic).
Connect this terminal to the power supply common terminal of a
transistor output (open collector output) device, such as a programmable
controller, in the source logic to avoid malfunction by undesirable current.
Common terminal for the 24 VDC power supply (terminal PC, terminal
+24).
Isolated from terminals 5 and SE.
Common terminal for the encoder pulse dividing output terminal.
Common terminal for the 24 V encoder power supply terminal (terminal
PG24).
Connect this terminal to the power supply common terminal of a
transistor output (open collector output) device, such as a programmable
controller, in the source logic to avoid malfunction by undesirable current.
Common terminal for contact input terminal (source logic).
Can be used as a 24 VDC 0.1 A power supply.
Common terminal for frequency setting signal (terminal 2 or 1) and
analog output terminal AM. Do not earth (ground).
Common terminal for terminals DO1, DO2, DO3. Isolated from terminals
SD and 5.
Common terminal for terminals S1 and S2.
Common terminal for terminal So (SO).
