The indicators are described as follows:
Indicator
No.
Name
Function
LED1
Status
indicator
This indicator is on when the extension card is establishing a
connection with the control board; it blinks periodically after
the extension card is properly connected to the control board
(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.
LED2
Disconnection
indicator
This indicator is off when A1 and B1 of the encoder are
disconnected; it is on when the encoder pulses are normal
LED3
Power
indicator
This indicator is on after the control board feeds power to the
PG card.
EC-PG505-24 can work in combination with multiple types of incremental encoders through various
external wiring modes. It is user-friendly, adopting spring terminals.
EC-PG505-24 terminals are described as follows:

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.
