Convo Inverter Cvf-s1 Manual Instant

The is the essential technical guide for installing, programming, and troubleshooting the CONVO CVF-S1 series of low-power, single-phase variable frequency drives (VFDs). Originally engineered by Shenzhen Convo Electric Technology (later integrated into the Bosch Rexroth portfolio), the CVF-S1 is widely deployed for controlling small industrial three-phase AC induction motors using a single-phase 220V power input.

is engineered for efficiency and reliability in demanding environments.

Programming the CVF-S1 is managed via the digital operation keypad. The system parameters are split into groups, utilizing functional code prefixes to manage drive behavior. Core Startup Settings Parameter Code Description Value Options & Functions Running Command Source 0 : Panel control keypad 1 : External wire terminals F0.03 Frequency Setting Source

: Reduce mechanical load, check motor sizing, and verify nameplate data matches parameters. E.OH (Inverter Overheating) Convo Inverter Cvf-s1 Manual

Routine maintenance is essential to keep the CVF-S1 operating reliably for years to come. The manual provides detailed checks and procedures.

The inverter is customized using parameters, often referred to in the . Key Function Settings (F-Codes) Description F0.02 Running Command 0: Keypad, 1: External Terminals, 2: Communication. F0.03 Frequency Source

Maximum output frequency up to 300 Hz with a carrier frequency ranging from 1.5 kHz to 15 kHz. The is the essential technical guide for installing,

Before installation or maintenance, you must follow these critical safety steps to prevent electric shock or equipment damage: High Voltage Warning

Multi-function digital inputs. By default, S1 is set to Forward (FWD) and S2 to Reverse (REV). S5 is typically used for an external Reset (RST).

| | Fault Description | Possible Causes | Proposed Solutions | | :--- | :--- | :--- | :--- | | Er.02 | Over-current during deceleration | Deceleration time is too short | Increase the deceleration time | | Er.04 | Over-voltage during acceleration | Input voltage too high / Frequent power switching | Check power supply voltage / Use control terminals to start/stop | | Er.05 | Over-voltage during deceleration | Deceleration time too short / Input voltage abnormal | Lengthen deceleration time / Check power supply / Install or re-select brake resistor | | Er.09 | Inverter overload | Load too large / Acceleration time too short / Torque boost too high / Low grid voltage | Reduce load / Lengthen acceleration time / Lower torque boost / Check grid voltage | | Er.11 | Inverter over-temperature | Heat sink blocked / High ambient temp / Fan damaged | Clean heat sink / Improve ventilation / Replace cooling fan | | Er.15 | IPM module fault | Output short-circuit or ground fault / Module damage | Check wiring / Contact manufacturer for service | Programming the CVF-S1 is managed via the digital

Connect the single-phase power supply to L and N (or R and T) terminals. Output to the motor is via U, V, and W. Control Terminals: S1-S5: Multi-function digital inputs.

: Check cooling fan operation and clear any vent obstructions. Wiring Faults

It is highly recommended to obtain the original manual provided by your distributor. However, general manuals for are available online, such as this VC Series User Manual.
