LED1
State 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 is disconnected; and it is on when the
pulses are normal.
LED3
Power indicator
This indicator is on after the control board feeds
power to the PG card.
The EC-PG503-05 extension card supports the input of absolute position signals and integrates the
advantages of absolute and incremental encoders. It is user-friendly, adopting spring terminals.
