Cable outlet for terminal boxes Outlet direction can be selected in steps of 90°
1) When using an absolute value encoder and non-ventilated or forced ventilation, the rated
torque is reduced by 10 % (refer to the Table, Technical data)
2) Power de-rating for temperatures > 40 °C and/or installation altitudes > 1000 m, refer to
the Configuration Manual "General Section for Synchronous Motors"
3) Forced ventilation cannot be used in the presence of flammable, corrosive, electrically
conductive or explosive dust.
4) 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 Heidenhain 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 foreign bodies above 0.01 μm.
