Sinovo VFD programming and configuration in Kenya: SD90, SD100, SD200 and SD300
Configuring Sinovo SD-series frequency inverters for pumps, fans and machines, including constant-pressure water supply and Modbus control.
Sinovo SD-series frequency inverters are used on pumps, fans and machines in Kenya and across Africa. We configure, commission and troubleshoot Sinovo drives, and set them up for constant-pressure water supply and PLC control.
Sinovo equipment we program and configure
| Equipment | Product families | Software we use |
|---|---|---|
| VFDs | SD90, SD100, SD200, SD300 | Keypad, Modbus |
Networks and protocols: Modbus RTU (RS-485) for control and monitoring from PLCs and HMIs.
What we do on Sinovo systems
- Motor data, control mode, ramps and protections
- Constant-pressure water supply with PID and a pressure transmitter
- Multi-speed and remote control from PLCs over Modbus
- Fault code diagnosis and replacement
How we work on your Sinovo system
- Back up first. Before we touch anything, we upload and save the existing program, HMI project and drive parameters, so the machine can always be returned to how it was.
- Understand the process. We walk the machine with your operators and maintenance team, and agree in writing what the change or new program must do.
- Program and test offline. Logic, screens and drive settings are prepared and checked before site work, to keep downtime short.
- Commission on site. We test every input, output, interlock and alarm with your team, then run the machine under real load.
- Hand over properly. You receive the final, commented program, HMI project, drive parameter files, I/O list and drawings, plus training for your technicians.
Practical tips from our engineers
Use a pressure transmitter, not a switch
For constant-pressure water supply, a 4–20 mA pressure transmitter and the drive's PID give steady pressure and lower energy use than on-off pressure switches.
Record every parameter change
Keypad-programmed drives are easy to change and easy to lose. A written parameter list saved with the panel drawings makes replacement straightforward.
