Troubleshooting & Maintenance
Before installation or maintenance, you must follow these critical safety steps to prevent electric shock or equipment damage: High Voltage Warning
Installation and maintenance should only be performed by trained technicians.
⚡ Map out the control circuit terminal wiring (like linking for external terminal control). Convo Inverter Cvf-s1 Manual
Install the inverter vertically to facilitate air circulation.
The wiring of a VFD is critical for both safety and performance. The main circuit terminals are used for the power supply input ( R , S , T ) and the motor output ( U , V , W ). The control circuit provides terminals for start/stop commands ( FWD , REV , CM ), analog frequency reference ( VI1 , ACM ), and various programmable digital inputs.
Before running the motor, input the values found on the motor's physical nameplate: Rated Motor Power (kW) H-04: Rated Motor Voltage (V) H-05: Rated Motor Current (A) H-06: Rated Motor Frequency (Hz) H-07: Rated Motor Speed (RPM) 2. Source of Run and Speed Commands b-01 (Command Source): 0 : Keypad control (START/STOP buttons on the VFD).
This manual is the essential resource for anyone installing, operating, or maintaining this inverter. To ensure safe and effective use, and to fully unlock the device's extensive capabilities, a thorough understanding of its documentation is critical. Sets how the drive is started and stopped
Low main input power supply; Blown fuse or loose connection. Verify input voltage meets specifications; Check wiring. Inverter Overload Continuous operation beyond rated current; Mechanical jam. Reduce load; Upgrade to a higher capacity inverter. E.OL2 Motor Overload Motor is stalled or overloaded at low speeds. Check motor cooling fan; Adjust V/F curve settings. E.OH Heatsink Overheating High ambient temperature; Blocked cooling fan. Clean dust out of heatsink; Replace broken cooling fan. Maintenance and Care
