The EC-PG504-00 expansion card can be used in combination with a resolver of excitation
voltage 7 Vrms. It is user-friendly, adopting spring terminals.
EC-PG504-00 terminals are described as follows:

Name
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.
This indicator is off when the encoder is disconnected;
Disconnection
it is on when the encoder signals are normal; and it
indicator
blinks when the encoder signals are not stable.
This indicator is on after the control board feeds power
to the PG card.

Function
Recommended resolver transformation ratio: 0.5
1. Factory setting of excitation: 10 kHz
2. Supporting resolvers with an excitation
voltage of 7 Vrms
1. Differential input of 5 V
2. Response frequency: 200 kHz
1. Differential output of 5 V
2. Frequency-divided output of resolver
simulated A1, B1, and Z1, which is equal to an
incremental PG card of 1024 pps.
3. Supporting frequency division of 1–255, which
can be set through P20.16 or P24.16
4. Max. output frequency: 200 kHz
