Compatibility and replacement
Order with the complete model MD500T3.7GB-INT: T is the 400 V class, 3.7 the heavy-duty rating in kW, GB a heavy-duty drive with built-in braking unit and -INT the international version.
If the nameplate of the old drive is unreadable, send us a photo of the drive and the motor nameplate and we will confirm the matching Inovance model before quoting.
Replacement checklist
- Braking resistor value and power
- Motor rated current and the duty (heavy or normal)
- Parameter backup from the old drive (keypad copy or PC software)
Frequently asked questions
Which fieldbus cards can it take?
Modbus-RTU (MD38TX1), CANlink (MD38CAN1), CANopen (MD38CAN2), PROFIBUS-DP (MD38DP2, frames T4-T12), PROFINET (MD500-PN1) and EtherCAT (MD500-ECAT), per the Inovance accessories list.
What motor power does it suit?
3.7 kW, with an output current of 9.0 A and 150% overload for 60 s, according to Inovance.
