Description
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.

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 HD2-E-PGIM 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.
