The following figure shows the external wiring of the PG card when it is used in combination with an
open-drain collector encoder. A pull-up resistor is configured in the PG card.

This indicator is on when the extension card is establishing a
connection with the control board; it blinks periodically after
Status the extension card is properly connected to the control board
indicator (the period is 1s, on for 0.5s, and off for the other 0.5s); and it
is off when the extension card is disconnected from the control
board.
This indicator is off when A1 and B1 of the encoder are
indicator disconnected; it is on when the encoder pulses are normal
Power This indicator is on after the control board feeds power to the
indicator PG card.
