Permissible movement of the drive element,dynamic

± 0.1 mm radial± 0.2 mm axial

Angular motion perpendicular to the rota-tional axis, static

± 0.005 mm/mm

Angular motion perpendicular to the rota-tional axis, dynamic

± 0.0025 mm/mm

Life of ball bearings 3.6 x 10^9 revolutions

Ambient data

Operating temperature range –30 °C ... +115 °C

Storage temperature range –40 °C ... +125 °C, without package

Relative humidity/condensation 90 %, Condensation not permitted

Resistance to shocks 100 g, 10 ms, 10 ms (according to EN 60068-2-27)

Frequency range of resistance to vibrations 20 g, 10 Hz ... 2,000 Hz (according to EN 60068-2-6)

EMC According to EN 61000-6-2 and EN 61000-6-3 1)

Enclosure rating IP40, with mating connector inserted (according to IEC 60529)

1) The EMC according to the standards quoted is achieved when the motor feedback system is mounted in an electrically conductive housing, which is connected tothe central earthing point of the motor controller via a cable screen. The GND-(0 V) connection of the supply voltage is also grounded here. If other shielding conceptsare used, users must perform their own tests.
