Lovato Electric VFD programming and commissioning in Kenya: VLB1, VLB3 and VLG3 drives
Lovato Electric VFD programming and commissioning by on-site engineers in Kenya and across Africa: VLB1, VLB3 and VLG3 drives. Drive keypad, fault finding, upgrades and full documentation.
Lovato Electric drives, starters and controllers are common in Kenyan motor control and switchboard panels. We configure and commission Lovato VLB and VLG drives for pumps, fans and machines.
Lovato Electric VFDs we work on
- VLB1 and VLB3: compact single- and three-phase drives
- VLG3: general-purpose drives for pumps, fans and machines
Software: Drive keypad, Lovato PC configuration software. Networks: Modbus RTU (RS-485).
Lovato Electric VFD services
- Motor data, ramps and protections
- PID constant pressure for pumps
- Modbus control from PLCs
- Fault diagnosis and replacement
Our drive commissioning checklist
- Motor nameplate data entered and an auto-tune or motor identification run completed
- Correct control mode for the load: V/F for fans and pumps, vector control for high starting torque
- Acceleration and deceleration ramps, current limits and braking set for the machine
- Protections set: motor overload, phase loss, earth fault, stall and dry-run where relevant
- Speed reference and start/stop from the right source: keypad, terminals, PID or fieldbus
- Parameters saved to a file and a printed list left with the panel drawings
Why drive set-up matters for your energy bill
- On centrifugal pumps and fans, power falls with the cube of speed. Running 20% slower uses roughly half the power (0.8³ ≈ 0.51).
- A correctly tuned drive starts motors smoothly, which cuts mechanical stress, water hammer and belt wear.
- Built-in PID control holds pressure or flow without throttling valves, which wastes energy.
- Energy counters in the drive show exactly what each motor uses, so savings can be measured.
Tips from our engineers
Combine with Lovato protection
Lovato motor protection circuit breakers and contactors pair well with Lovato drives in compact panels.
Record the parameter list
Keypad-set drives are easy to change and hard to recover. A written parameter list saved with the drawings avoids guesswork.

Frequently asked questions
Can you set up Lovato VLB drives?
Yes. We configure VLB1, VLB3 and VLG3 drives, including PID and Modbus control.
