2. Definition of VFD580 control circuit terminals:
| Type | Terminal symbol | Terminal Name | Terminal function description |
Analog input |
VREF |
Analog input reference voltage | VREF can choose 10V or 15V, switch between 10V and 15V of VREF through the "VREF" toggle switch, the factory default is 10V 10V±3%, |
| 10V±3% , 15V±3% | |||
| The maximum output current is 30mA, that is, the recommended external potentiometer resistance range: 1kΩ ~51kΩ | |||
| GND | Analog input ground | Internally isolated from COM, 0V | |
| AI1 | Analog input 1 | Only input voltage:-10V~10V:lmpedance 20kΩ | |
AI2 |
Analog input 2 | Input voltage:0~10V :lmpedance 20kΩ , Maximum input voltage | |
| I Input current:0~20mA:lmpedance 500Ω , Maximum input current | |||
| Through the jumper switch AI2 0 ~ 10V and 0 ~ 20mA analog input switch, the factory default voltage input. | |||
AI3 |
Analog input 3 | Input voltage:0~10V :lmpedance 20kΩ , Maximum input voltage | |
| Input current:0~20mA:lmpedance 500Ω , Maximum input current | |||
| Through the jumper switch AI3 0 ~ 10V and 0 ~ 20mA analog input switch, the factory default voltage input. | |||
Analog output | AO1 | Analog output 1 | Output 0 ~10v: lmpedance >10kΩ |
AO2 |
Analog output 2 | Output voltage:0~10V :lmpedance >10kΩ | |
| Output current:0~20mA:lmpedance 200Ω~500Ω | |||
| Through the jumper switch AO2 0 ~ 10V and 0 ~ 20mA analog output switching, the factory default voltage output. | |||
| GND | Analog ground | Internal isolation from COM and 0V | |
Switch input |
+24V |
+24V current | 24V ± 10%, internally isolated from GND and 0V |
| Maximum output current :200mA | |||
| To provide 24V power supply, generally used as a digital input and output terminal power supply and external sensor power. | |||
| When the "24V/PLC" toggle switch is ON, +24V and PLC are connected | |||
PLC | Digital input terminal common | The factory default setting is connected PLC with +24V terminal for on-off input high and low level switch | |
| When using the external power input, it will disconnect the connector slip of PLC with the +24V | |||
| COM | +24V ground | Internal isolation from GND and 0V | |
DI1 ~DI4 /DI6 ~DI7 | Digital input terminal 1-4 or 6-7 | Optocoupler isolation, compatible with bipolar input | |
| Frequency range:0~200Hz | |||
| Voltage range:10V~30V | |||
HDI | Digital input terminal /High-speed pulse input | igital input terminal :same as DI1~DI4 and DI6-DI7 | |
| Pulse input frequency input :0~50KHz | |||
| Voltage range:15V~30V | |||
Switch output |
DO1 |
Open collector output | Optocoupler isolation |
| Voltage range:0V~28V | |||
| Current range:0mA ~50mA | |||
| YCOM | DO1 Ground | Internally isolated from GND, 0V, COM | |
HDO | Open collector output /High-speed pulse output | Open collector output :same as DO1 | |
| High-speed pulse output :0~50KHz | |||
| COM Reference ground is COM | |||
| Relay 1 | T1A/T1B/T1C | Relay 1 output | T1A-T1B :normal close |
| T1A-T1C:normal open | |||
| Relay 2 | T2A/T2B/T2C | Relay 2 output | T2A-T2B :normal close |
| T2A-T2C:normal open |
