Hybrid cable length vs. KMV03 performance
The maximum allowed hybrid cable length of a drive line can be determined
using the power required by the servo drives.
The maximum number of drives per drive line depends on the
following factors:
● DC bus power
● Power requirement of the control voltage
● Y‑capacitance
● Leakage capacitance
● Cable length
The KNK mains filter always limits the maximum number to 14.
If necessary, install an additional KMV device.
In the following paragraphs, we distinguish 3 cases:
A:
Servo drives evenly distributed over the entire drive line
The servo drives are evenly distributed over the entire length of the drive line.
The cables between the individual servo drives all have the same length.
B:
Servo drives evenly distributed at the end of the drive line
The servo drives are arranged at the end of the drive line and interconnected
with short cables (1 m).
C:
Servo drives evenly distributed starting at 20% of the drive line
The first servo drive is arranged at 20% of the length of the entire drive line.
After this, the servo drives are evenly distributed up to the end of the drive
line.
The figure below shows the maximum allowed hybrid cable length of a drive
line depending on P
42V
(P
42V
= KMV output XD10 load).
