The switch SW1 is used to set the voltage class (5 V or 12 V) of the power supply of the encoder. The
switch can be operated with an auxiliary tool.
The terminals are arranged as follows:

Indicator definition
Indicator
Name
Function
LED1
State 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
When the encoder is rotating, this indicator blinks when A1 or B1 of
the encoder are disconnected; otherwise it is always on.
LED3
Power indicator
This indicator is on after the control board feeds power to the PG
card.
The SPG505-12 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.
