Indicator
Name
Description
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.
The EC-PG505-12 expansion card can be used in combination with multiple types of incremental
encoders through different modes of wiring. It is user-friendly, adopting spring terminals.
