The manual provides the register map. Address 0x2000 is the Communication Control Word. Writing 0x01 starts the drive; writing 0x06 stops it. Address 0x2001 is the frequency register (scaled 0-10000 for 0.00Hz to Max Frequency).
F002 = 1 (VI analog input)
F003 = 1 (Terminal control)
F005 = 60 (if motor is 60 Hz)
F014 = motor nameplate current (e.g., 2.7A)

Cons:
Best for: Experienced technicians, maintenance teams, or anyone already familiar with VFDs. Not ideal for first-time inverter users.
Suggested improvement: Add a flowchart for common setups (e.g., external potentiometer, start/stop via terminals) and a one-page quick reference.
This report outlines the technical specifications and operational guidelines for the Convo CVF-S1 Series
, a low-power single-phase vector inverter primarily used for general industrial applications. 1. Product Overview The Convo CVF-S1
(now part of the Bosch Rexroth portfolio) is a Variable Frequency Drive (VFD) designed for precision control of AC induction motors. Power Range: Typically 0.4 kW to 4.0 kW. Convo Inverter Cvf-s1 Manual
Input Specifications: Single-phase AC, 180V–260V at 50/60 Hz.
Output Specifications: Three-phase AC, 0V–220V with current ratings around 4.7 A (for the 0.75 kW model). 2. Core Technical Specifications Key operating parameters from the Instruction Manual: Control Mode: Digital SVPWM (Space Voltage Vector Control). Carrier Frequency: 1.0–16.0 kHz adjustable.
Frequency Range: 0.10 Hz to 650.00 Hz (adjustable via panel potentiometer, terminals, or analog inputs).
Overload Capacity: 150% rated current for 1 minute (general purpose). 3. Installation & Safety Requirements
Environment: Indoor use only, below 1,000m altitude (derating required above this). Temperature should be between and with no dew. Mounting: Wall-mounted or floor cabinet types. Wiring Hazards: Do not connect input power to U, V, W output terminals.
Ensure the grounding terminal is reliably connected to avoid electrified housing.
Wait at least 15 minutes after power-off before servicing to allow capacitors to discharge. 4.

The Convo CVF-S1 Go to product viewer dialog for this item. is a variable frequency drive (VFD) designed for general industrial applications using three-phase AC induction motors. The Convo Inverter CVF-S1 Instruction Manual provides essential details on wiring, safety, and parameter configuration. 1. Control Terminal Wiring The manual provides the register map
The CVF-S1 features several digital and analog input/output terminals for remote control: COM: Common port for digital signals.
S1 – S5: 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).
AVI: 0–10V analog input for frequency setting via an external potentiometer.
ACI: 4–20mA analog input for external current-based speed control.
RA, RB, RC: Relay output terminals (AC 250V/3A) for status signals like "Fault" or "Running". 2. Key Parameter Settings
Programming involves entering the parameter code (e.g., F0.02) and modifying its value. Description Default / Range F0.02 Running command 0: Keypad control; 1: Terminal control F0.03 Frequency setting 0 (Panel Pot) 0: Panel; 3: AVI (0-10V); 5: ACI (4-20mA) F0.04 Max frequency Standard standard for acceleration/deceleration F0.05 Upper limit freq Prevents the motor from exceeding a safe speed F0.23 User's code Used for password protection (0-9999) 3. Operational Safety
Grounding: The ground terminal must be reliably grounded to prevent the risk of electric shock through the VFD housing.
Ventilation: Install the inverter in a well-ventilated environment to prevent overheating during operation.
Initialization: To restore factory settings, look for the parameter initialization code (often under group 'b' or 'H' in similar Convo series). Title: Comprehensive but could use better organization –
Detailed diagrams and full parameter lists are available in the Instruction Manual PDF hosted on Aliyun or through the Sigi-Elect archive.
The Convo CVF-S1 is a compact, high-performance general-purpose AC drive (VFD) designed for controlling the speed of three-phase induction motors. Common applications include conveyors, fans, pumps, and small machinery.
Key Specifications (Typical) | Model Range | 0.4kW – 7.5kW | |-------------|----------------| | Input | 1PH 220V or 3PH 380V (check your label) | | Output | 3-phase variable voltage / variable frequency | | Frequency | 0.00 – 400.00 Hz | | Control | V/F, Sensorless Vector (depending on version) |
⚠️ Always verify your unit’s rating plate before applying power.
The Convo Inverter Cvf-s1 Manual is not a one-time read. It is a living document that you will reference for parameter tuning, fault tracing, and system integration. Bookmark the PDF on your smartphone, keep a printed copy inside the electrical panel, and always refer to the "Parameter List" flowchart before making changes.
By mastering this manual, you transform the CVF-S1 from a confusing black box into a precise tool that extends the life of your motors and saves energy. If you have lost your copy, do not rely on online forums for specific hex codes—download the official manual directly from Convo's support portal today.
Disclaimer: This guide synthesizes information typical of the Convo CVF-S1 series. Actual parameter addresses (e.g., F0.19) may vary slightly by firmware revision. Always verify with your specific printed manual or the PDF provided by your distributor.
The manual contains hundreds of parameters, but you only need a few core groups to get the motor running.
