TD350 Series VFD Extension cards
-325-
A.7.6 Simple 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.

Definition
Function
LED1
State indicator
On: The extension card is establishing a connection with
the control board.
Blinks periodically: 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).
Off: The extension card is disconnected from the control
board.
LED2
Disconnection
indicator
Off: A1 and B1 of the encoder are disconnected.
On: The encoder pulses are normal.
LED3
Power indicator
On: The control board feeds power to the PG card.
The EC-PG507-12 extension card can be used in combination with multiple types of incremental
encoders through different modes of wiring. The wiring modes are the same as those for
EC-PG505-12.
