Indicator Name Function
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 the encoder is disconnected;
it is on when the encoder signals are normal; and it
blinks when the encoder signals are not stable.
LED3 Power indicator This indicator is on after the control board feeds power
to the PG card.
The HD2-E-PGR extension card can be used in combination with a resolver of excitation
voltage 7 Vrms. It is user-friendly, adopting spring terminals.
