Indicator
Name
Function
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); and it
is off when the expansion card is disconnected from the
control board.
LED2
Disconnection
indicator
When the encoder is rotating, this indicator blinks when A1 or
B1 of the encoder are disconnected; otherwise it is always on.
LED3
Power indicator
This indicator is on after 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.
