Technical Data
1) 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.
2) This is the peak output current limited by hardware regulation. The software current control reserves 5% for closed loop regulation.
3) This is the maximum carrier frequency the power stage can support. The actual operating carrier frequency is adjusted and limited by the control
card.
4) 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.
5) Max motor cable length when using shielded cable, KEB EMI  lter, and the installation must conform to EN55011 / EN55022.
