8.3.3 Cable and Wire Requirements
8.3.3.1 Cable material
For information on the chemical, mechanical, and electrical characteristics of the cables
please refer to the
Kollmorgen 2G Cable Guide
or contact customer support.
To reach the maximum permitted cable length, you must use cable material with the fol-
lowing capacitance requirements:
Motor power cable: less than 150 pF/m (phase core to shield capacitance)
Motor Feedback cable: less than 120 pF/m (signal core to shield capacitance)
Hybrid motor cable:
- less than 120 pF/m (phase core/core capacitance)
- less than 210 pF/m (phase core/shield capacitance)
- less than 120 pF/m (signal core/core capacitance)
- less than 210 pF/m (signal core/shield capacitance)
- BUS Element: 45 pF/m @ 800kHz & charact. wave resistance 110±10Ω @ 10MHz
8.3.3.2 Cable Length
Cables should not exceed the maximum lengths stated below. The recommended max-
imum cable length of motor cables depends on the used cable material and the feedback
type. Cable functionality is only guaranteed up to the maximum length when using unmod-
ified Kollmorgen engineered cables.
Motor cables (X1, X2, X4, X5, X23, X41)
Length of motor power cables, feedback cables and motor brake cables is equal.

I/O cables (X21, X22)
Maximum distance for unshielded I/O lines is 3 m inside the cabinet. If the I/O cable leaves
the cabinet, it must be EMC shielded.
8.3.3.3 T-Connector wiring
If you use mating T-connectors for 24 VDC supply, mains voltage supply and DC-Bus link,
you must prepare the connecting cables with wire end ferrules.
You can prepare cables with cross-section 2.5 mm² (up to to 6 mm²) with a uniform length of
170 mm, if the modules are lined up close together.
Use wire end ferrules with plastic collars, for example 2.5 mm² x 17 mm.
