Recommendations for cables (material and construction (ð p. 59)).
Following IEC 60204 (B2), we recommend for single-axis systems:
Interface
AC connection
DC bus link
Brake resistor
Motor cables
Resolver, motor thermal control,
max.100m*
Encoder, motor thermal control,
max. 50m*
ComCoder, motor thermal con-
trol, max. 25m
Set points, AGND, max 30m
Control signals, BTB, DGND,
max. 30m
Holding brake (Motor)
+24 V Electronics, max 30m
NOTICE
+24 V Motor brake, max 30m
For multi-axis systems, observe the specific operating conditions for your system.
To reach functional safety with the max. permitted cable length, observe cable
requirements ð p. 59.
* Kollmorgen North America supplies cables up to 39 meters
*
Kollmorgen Europe supplies cables up to max. length
