Genuine Inovance MD290 drive MD290T18.5G/22PB-INT – 18.5 kW heavy duty (G) / 22 kW normal duty (P), three-phase 380–480 V, 37 A / 45 A, frame T5.
This drive converts the fixed mains supply into a variable voltage and frequency for the motor; the dual G/P rating lets the user choose heavy-duty or normal-duty operation by parameter.

Compatibility and replacement
Order with the complete model MD290T18.5G/22PB-INT: in MD290 codes the T stands for the 400 V class, 18.5G/22P gives the heavy-duty and normal-duty ratings, B the built-in braking unit and -INT the international version.
The ratings in the table are taken from the official Inovance MD290 brochure (inovance.eu). If your old drive shows different values, send us a photo of its nameplate and we will check it.
Replacement checklist
- Option cards and remote keypad of the old drive
- Braking resistor value and power
- Motor rated current and the duty (heavy or normal)
