MD310T11B-INT is a candidate for linking a production-line fan speed command to central control. Its 11 kW motor class corresponds to a 25 A output rating. Selection should use the actual fan operating point, panel temperature and motor nameplate; the current rating of an existing contactor does not establish the required drive size.
Technical specifications
| Motor class | 11 kW |
|---|---|
| Rated input | 3-phase 380-440 VAC |
| Output current (6 kHz) | 25 A |
| Rated input current | 26 A |
| Control methods | V/f; SVC |
| Communications | Modbus RTU (RS485) |
| Frequency ceiling | SVC: 300 Hz; V/f: 500 Hz |
| Overload | 150% / 60 s; 180% / 2 s |
| Braking unit | Built in; resistor selected separately |
| Protection | IP20 |
Current is rated at 6 kHz carrier frequency. Derating applies above 40 °C. Confirm enclosure depth and clearances from the exact-code drawing.
Application selection
Record fan acceleration time, restart conditions with a rotating load and ambient temperature. Automatic restart requires a machine-safety assessment.
Can the existing contactor rating determine drive size?
Contactor utilisation categories and drive continuous-output ratings are assessed differently. Use the motor nameplate and actual load cycle.
Installation and commissioning
Qualified personnel must use the exact-model manual for installation and commissioning. Apply lockout before physical inspection, retain project/parameter backups and never bypass protective functions.
