Drive categories The large number of different drive applications can be divided into five categories. The
five categories are listed below together with the recommended inverter. The assign-
ment is based on the required setting range and the resulting control process.
1. Drives with a base load and a speed dependent load, such as conveyor drives.
• Low requirements on the setting range.

• High requirements on the setting range (motor with encoder).
– MOVIDRIVE

MDX61B with DEH11B option
2. Dynamic load, e.g. trolleys; brief high torque demand for acceleration followed by low
load.
• Low requirements on the setting range.

• High dynamic properties required (motor with encoder, preferably sin/cos encoder).

3. Static load, e.g. hoists; mainly steady high static load with overload peaks.
• Low requirements on the setting range.

4. Load falling in inverse proportion to speed, e.g. winding or coil drives.
• Torque control (motor with encoder, preferably sin/cos encoder).

5. Variable torque load, e.g. fans and pumps.
• Low load at low speeds and no load peaks, 125% utilization (I

= 125% I

).
