How to Install Convo Inverter CVF-S1?
Before installing the Convo Inverter CVF-S1, you need to make sure that you have the following items:
A suitable motor that matches the inverter's specifications
A power supply cable that meets the inverter's voltage and current requirements
A motor cable that meets the inverter's output frequency and current requirements
A grounding cable that meets the inverter's grounding resistance requirements
An external control device, such as a potentiometer, a switch, a PLC, etc., if needed
A cooling fan or an air conditioner, if needed
After preparing the above items, you can follow these steps to install the Convo Inverter CVF-S1:
Choose a suitable installation location that meets the environmental requirements of the inverter, such as temperature, humidity, dust, vibration, etc.
Mount the inverter on a flat and solid surface with screws or bolts. Make sure that there is enough space around the inverter for ventilation and maintenance.
Remove the operation panel and the cover plate of the inverter by loosening the screws.
Connect the power supply cable to the input terminals L and N of the inverter. Make sure that the cable is securely fastened and insulated.
Connect the motor cable to the output terminals U, V and W of the inverter. Make sure that the cable is securely fastened and insulated.
Connect the grounding cable to the grounding terminal PE of the inverter. Make sure that the cable is securely fastened and has a low resistance.
Connect the external control device to the input terminals X1 to X7 of the inverter according to your needs. Make sure that the device is compatible with the inverter's input voltage and current.
Reinstall the cover plate and the operation panel of the inverter by tightening the screws.
Turn on the power supply and check if the LED display shows "rdy" (ready) or "Err" (error). If there is an error code, refer to the troubleshooting section of this manual.
How to Operate Convo Inverter CVF-S1?
After installing the Convo Inverter CVF-S1, you need to set some basic parameters before operating it. You can use the operation panel or an external control device to set these parameters. Here are some important parameters that you need to set:
b-0: Selects the basic operating parameter group
b-1: Selects the frequency input channel (0: operation panel; 1: external analog input; 2: external digital input)
b-2: Sets the upper limit frequency (0.5-400 Hz)
b-3: Selects the run command channel (0: operation panel; 1: external terminal)
b-5: Sets the motor rated frequency (50 or 60 Hz)
b-6: Sets the motor rated voltage (220 or 240 V)
b-7: Sets the acceleration time 1 (0.1-6000 s)
b-8: Sets the deceleration time 1 (0.1-6000 s)
After setting these parameters, you can use one of these methods to operate
the Convo Inverter CVF-S1:
If you use the operation panel as your control device, you can press
the RUN/STOP button to start or stop
the inverter. You can also use
the UP/DOWN buttons to adjust
the output frequency.
If you use an external analog input as your frequency input channel,
you can connect a potentiometer or
a voltage/current signal source
to terminal X3 or X4 of
the inverter. You can adjust
the potentiometer or
the signal source to change
the output frequency.
If you use an external digital input as your frequency input channel,
you can connect up to 15 switches
to terminals X3 to X7 of
the inverter. You can set different
frequencies for each switch by using
parameters L-18 to L-32. You can turn on or off
the switches to select
the output frequency.
If you use an external terminal as your run command channel,
you can connect a switch or
a PLC signal to terminal X1 or X2 of
the inverter. You can turn on or off
the switch or
the signal to start or stop
the inverter.
