The indicators are described as follows:
Indicator No.
Name
Function
LED1
Status 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 A1 and B1 of the
encoder is disconnected; and it is on when the
pulses are normal.
LED3
Power indicator
This indicator is on after the control board feeds
power to the PG card.
The EC-PG505-12 extension card can be used in combination with multiple types of incremental
encoders through different modes of wiring. It is user-friendly, adopting spring terminals.
EC-PG505-12 terminal function description
EC-PG505-12 terminals are described as follows:
Signal
Port
Terminal function
PE
Protective earth
terminal
Connected to the ground to enhance anti-interference
performance.
GND
Ground
Ground of the PCB internal power.
PWR
Encoder power
Voltage: 5V/12V ± 5%
Max. current: 150 mA
The voltage class can be selected through SW1,
depending on the encoder voltage class.
(PGND is the isolation power ground.)
