Indicator definition
Indicator Name Description
LED1 State indicator
On: The expansion card is establishing a connection
with the control board.
Blinking periodically: 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).
Off: The expansion card is disconnected from the
control board.
LED4 Power indicator
On: The control board feeds power to the expansion
card.
The EC-IO501-00 expansion card can be used in scenarios where the I/O interfaces of a
Goodrive350-UL VFD cannot meet the application requirements. It can provide 4 digital inputs, 1
digital output, 1 analog input, 1 analog output, and two relay outputs. It is user-friendly, providing relay
outputs through European-style screw terminals and other inputs and outputs through spring
terminals.

1. Input range: 0
–10 V, 0–20 mA
2. Input impedance: 20 kΩ for voltage input;
250 Ω for current input
3. Set it to be voltage or current input
through the corresponding function code.
4. Resolution: When 10 V corresponds to
50 Hz, the minimum resolution is 5 mV.
