Name
Description
LED1
State indicator
On: The expansion card is establishing a connection with the
control board.
Blinking periodically: The expansion card is properly connected to
the control board (the period is 1s, on for 0.5s, and off for the other
0.5s).
Off: The expansion card is disconnected from the control board.
LED2
Disconnection
indicator
This indicator blinks only if A1 or B1 signal is disconnected during
encoder rotating; and it is on in other cases.
LED3
Power indicator
On: The control board feeds power to the PG card.
SPG505-24 can work in combination with multiple types of incremental encoders through various
external wiring modes. It is user-friendly, adopting spring terminals. AO-, BO-, AND ZO- are internally
short connected to PGND.
