5.2.10 Motor cable

ƒ The used motor cables must

– meet the requirements on site (e.g. EN 60204−1, UL),

– comply with the following voltage data: EN 0.6/1 kV, UL 600 V.

ƒ For shielded motor cables, only use cables with braid made of tinned or

nickel−plated copper. Shields made of steel braid are not suitable.

– The overlap rate of the braid must be at least 70 % with an overlap

angle of 90°.

ƒ Use low−capacitance motor cables:

 Note!

ƒ The motor cable must be as short as possible for having a

positive effect on the drive behaviour.

ƒ If EMC requirements must be met, the permissible cable

length may be affected.

ƒ EVS9321−xPand EVS9322−xP: At a mains voltage of 480 V and

a switching frequency f

chop

= 16 kHz, the maximum

permissible cable length is reduced if the motor cable has

more than a single core:

– The following holds true for two parallel single cores:

max

= 17 m

– The following holds true for three parallel single cores:

max

= 9 m
