Resistance to shocks:100 g, 6 ms (according to EN 60068-2-27)
Resistance to vibration: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:IP 66, according to IEC 60529, with mating connector inserted
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 to the central earthing point of the motor controller via a cable screen. This is also where the GND (0 V) connection of the power supply voltage is linked to earth. Users must perform their own tests when other screen designs are used.
