Description of the motor

2.4 Derating factors

Any danger areas encountered during normal operation and when maintaining and servicing
the motor must be identified using clearly visible warning and prohibit signs (pictograms) in
the immediate vicinity of the danger (close to the motor). The associated texts must be
available in the language of the country in which the product is used.
2.4 Derating factors
For installation altitudes more than 2000 m above sea level, reduce the voltage stress of the
motors according to the "Factors to reduce the maximum DC link voltage" table (reciprocal
values from EN 60664-1 Table A. 2).
Table 2- 5
Installation altitude above sea level in m up to
Reducing the DC link voltage reduces the converter output voltage. The operating range in
the M-n diagram is also reduced.
You can find the M-n diagrams in the associated data sheet.
Operation in a vacuum is not permissible due to the low voltage strength and the poor
cooling.

Selection and ordering data

2.5.1

Order designation

The article number serves as order designation. The article number (MLFB) comprises a
combination of digits and letters. When placing an order, it is sufficient just to specify the
unique Article number.
The Article number consists of three blocks that are separated by hyphens. The first block
has seven positions and designates the motor type (1FW6), the frame size and the cooling
method. Additional features are coded in the second and third blocks.
Please note that not every theoretical combination is possible.
