-
The motor cable should be as short as possible because of the positive
effect on the drive characteristic.
- FIG 4-19 shows the relation between the motor cable length and the
possibly required output filters.
- For group drives (several motors connected to one controller) it is
necessary to calculate the resulting cable length I

- The components stated in FIG 4-19 are valid for chopper frequencies
$
8 kHz (C018 = -0-, -1-). When using controllers with chopper
frequencies > 8 kHz, different measures may be required. Please contact
Lenze.
- When using unscreened motor cables, the data indicated in FIG 4-19 are
valid for the double motor cable length.
- Please contact Lenze when the absolute or resulting motor cable lengths
are > 200 m.
