The terminals are arranged as follows:

CME and COM are shorted through J3 before delivery, and J5 is the jumper for selecting the output type (voltage or current) of AO2.

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.

LED4

Power indicator

This indicator is on after the IO expansion card   is powered on by the control board.

The EC-IO501-00 expansion card can be used in scenarios where the I/O interfaces of the 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-type screw terminals and other inputs and outputs through spring terminals.

Power

PW

External power supply

The working power   of digital input is provided by an external power supply.

Voltage range: 12–24   V

The terminals PW   and +24V are shorted before delivery.

Analog input/output

AI3—GND

Analog input 1

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.

5. Deviation:±0.5%;   input of 5 V or 10 mA or higher at the temperature of 25°C

AO2—GND

Analog output 1

1. Output range:   0–10 V, 0–20 mA

2. Whether it is   voltage or current output is determined by J5.

3. Deviation ±0.5%;   input of 5 V or 10 mA or higher at the temperature of 25°C

Digital input/output

S5—COM

Digital input 1

1. Internal   impedance: 3.3 kΩ

2. Power input   range: 12–30 V

S6—COM

Digital input 2

S7—COM

Digital input 3

S8—COM

Digital input 4

Y2—CME

Digital output

1. Switch   capacity: 200 mA/30 V

2. Output   frequency range: 0–1 kHz

3. The terminals   CME and COM are shorted through J3 before delivery.

Relay output

RO3A

NO contact of relay 3

1. Contact   capacity: 3A/AC 250 V, 1 A/DC 30 V

2. Do not use   them as high-frequency digital outputs.
