How to Install and Operate a Convo Inverter CVF-S1
A Convo inverter CVF-S1 is a type of variable frequency drive (VFD) that can control the speed and torque of an AC motor. It is manufactured by Bosch Rexroth Electronic & Control Shenzhen Co., Ltd., a subsidiary of the German Bosch Group. A Convo inverter CVF-S1 can be used for various applications, such as pumps, fans, conveyors, compressors, etc.
In this article, we will show you how to install and operate a Convo inverter CVF-S1 properly. We will also provide some troubleshooting tips and a link to download the user manual for more details.
Before installing the Convo inverter CVF-S1, make sure you have the following items:
A suitable power supply (single-phase or three-phase) with a voltage range of 200-240V or 380-480V.
A suitable motor that matches the power rating and voltage of the inverter.
A suitable cable for connecting the power supply, the inverter, and the motor. Use shielded cable if the motor is more than 30 m from the inverter.
A suitable fuse or circuit breaker for protecting the inverter from overcurrent.
A suitable grounding wire for connecting the inverter to the earth.
A suitable enclosure or cabinet for mounting the inverter if it is not installed in a clean and dry environment.
Follow these steps to install the Convo inverter CVF-S1:
Mount the inverter on a flat and vertical surface with enough space for ventilation and cooling. Avoid direct sunlight, dust, moisture, corrosive gas, vibration, and electromagnetic interference.
Connect the power supply cable to the input terminals L1, L2, L3 (and N for single-phase) of the inverter. Make sure the power supply voltage matches the voltage rating of the inverter.
Connect the motor cable to the output terminals U, V, W of the inverter. Make sure the motor voltage matches the voltage rating of the inverter.
Connect the grounding wire to the PE terminal of the inverter. Make sure the grounding resistance is less than 100 ohms.
Connect any external control devices (such as switches, potentiometers, sensors, etc.) to the input/output terminals S1-S7, COM, PW, +24V of the inverter. Refer to the user manual for more details on how to configure these terminals.
Turn on the power supply and check if the display panel of the inverter shows any error codes or warnings. If yes, refer to the user manual for troubleshooting.
After installing the Convo inverter CVF-S1, you can operate it using one of these methods:
The keypad on the front panel of the inverter. You can use it to set parameters, start/stop/run commands, frequency settings, etc.
The external control devices connected to the input/output terminals of the inverter. You can use them to set parameters, start/stop/run commands, frequency settings, etc.
The communication interface (RS485 or CAN) on the side panel of the inverter. You can use it to connect to a PC or a PLC and control the inverter remotely.
To operate the Convo inverter CVF-S1 using the keypad, follow these steps:
Press MODE key to enter parameter mode. Use UP/DOWN keys to select a parameter group (b-0 b-9) or an individual parameter (L-0 L-99).
Press ENTER key to confirm your selection. Use UP/DOWN keys to change the parameter value.
Press ENTER key again to save your setting. Press ESC key to exit parameter mode.
Press RUN key to start running. Use UP/DOWN keys to adjust frequency setting. Press STOP key to stop running.
