When using an absolute encoder and natural cooling or forced ventilation, the rated torque is reduced by 10 %
1)
(refer to "Selection and ordering data")
Power de-rating for temperatures > 40 °C and/or installation altitudes > 1000 m, refer to the Configuration Manual
2)
"General Section for Synchronous Motors"
Forced ventilation cannot be used in the presence of flammable, corrosive, electrically conductive or explosive dust.
3)
The max. operating frequency of 432 Hz must be observed with SIMODRIVE 611 universal
4)
(encoder frequency = speed x pole pair number / 60).
5) For motors with degree of protection IP67 and IP68, since 01/2001, an M5 inner thread is provided in the cover on
the NDE. This allows compressed air to be connected. The pressure in the motor should be within the range from
0.05 to 0.1 bar.
The compressed air must be dry and clean. For instance, the DA300 compressed air service unit from the Heiden-
hain company can be used.
For 1FT6 motors without optical encoders, it is sufficient to have a pre-filter that filters out any foreign bodies above
3 µm.
For 1FT6 motors with optical encoder, in addition to the pre-filter element, a fine filter is required that filters out for-
eign bodies above 0.01 µm.
