Definition
Function
LED1
Status indicator
This indicator is on when the expansion card is
establishing a connection with the control board; it
blinks periodically after 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
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.
EC-PG704-00 can be used in combination with a resolver of excitation voltage 7 Vrms. It is user-friendly, adopting spring
cage terminals.
