1) The 28 W housing can either be fed with one large set of wires or two smaller sets of wires, double feed. See Mat. No. 00F50EB-KW00 from KEB.
2) The wire gauge is based on the maximum fuse rating, copper wire with a 75°C insulation rating, THHW, or equivalent. If circuit protection is selected based on the actual
input current, the wire size could be reduced.
3) This is the peak output current limited by hardware regulation. The software current control reserves 5% for closed loop regulation.
4) This is the maximum carrier frequency the power stage can support. The actual operating carrier frequency is adjusted and limited by the control card.
5) This is the power dissipation at the rated carrier frequency, rated voltage, and rated load. Operation at reduced carrier frequencies or reduced load will decrease this value.
6) 12kHz
7) Max motor cable length when using shielded cable, KEB EMI filter, and the installation must conform to EN55011 / EN55022.
8) Min. resistance applies to 50% duty cycle.
