A.7.6 Simplified incremental PG card——EC-PG507-12
The terminals are arranged as follows:
The DIP switch SW1 is used to set the voltage class (5 V or 12 V) of the power supply of the
encoder. The DIP switch can be operated with an auxiliary tool.

EC-PG507-12 can work in combination with multiple types of incremental encoders through
various external wiring modes, which are similar to the wiring modes of EC-PG505-12.
EC-PG507-12 terminals are described as follows:

This indicator is on when the expansion card is establishing
a connection with the control board; it blinks periodically
Status after the expansion card is properly connected to the control
indicator 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 A1 and B1 of the encoder are
indicator disconnected; it is on when the encoder pulses are normal.
Power This indicator is on after the control board feeds power to the
indicator PG card.

The voltage class can be selected through SW1,
depending on the encoder voltage class.
(PGND is the isolation power ground.)
