9 General Information Regarding the
Wiring
9.1 General Information
The cables described in this section correspond to the requirements, SIEB & MEYER
AG demands for the correct function of the cable connection.
If cables are exposed to mechanical strain inside of the machine, e.g. in trailing
chains or similar components, the machine manufacturer must take care for only us-
ing adequate cables.
In general, the following principles apply for the cables (see also separate documen-
tation "Unit Assembly Complying EMC and Supply System Types“):
X Motor and signal cables must not be wired in the same cable protection hose!
X Motor cables must have a wire-meshed shield. They must be wired separately
from signal cables.
X Signal lines must have a wire-meshed shield. Difference signals should only be
transmitted via lines twisted in pairs. They must be wired separately from motor
cables.
X The cable shields must be connected to the connector shell inside of the con-
nectors. In the control cabinet they should be connected to a ground bus.
X Cable shields not ending in a connector inside of the control cabinet such as mo-
tor cables must be connected to the ground bus.
X Both ends of the shield of shielded cables must generally be connected to the
shell.
The line cross-sections should be selected carefully so that the maximum admissible
current is not exceeded at the maximum ambient temperature (the maximum ambi-
ent temperature of the servo module is 60°C).
DIN EN 60204-1 defines the admissi-
ble values for the separate line cross-sections which must absolutely be taken into
account.
The current carrying capacity in connection with the line cross-section of copper con-
ductors isolated with PVC or cables according to DIN/EN 60204-1 for wiring type B2
and an ambient temperature of + 40°C are indicated in the following table:
Conductor cross-section A
[mm²]
Admissible current I [A]
0,75 7,60
1,00 9,60
1,50 12,20
2,50 16,50
4,00 23,00
6,00 29,00
10,00 40,00
16,00 53,00
25,00 67,00
35,00 83,00
