Requirements for the motor supply cables
The cables must be appropriately selected corresponding to the mechanical forces caused
by high rates of acceleration and speeds. Further, they must be suitable for the bending
stresses that occur.
Permissible motor feeder cable lengths
The permissible length of the power cable between the motor and the infeed unit depends on
the rated power or the rated output current of the infeed unit.
Example, Motor Module, shielded cable:
up to 50 m power cable length at the rated output current
I
N
≤ 9 A,
up to 70 m power cable length at the rated output current 9 A <
I
N
≤ 18 A,
up to 100 m power cable length from a rated output current
I
N
≥ 30 A
The permissible signal cable length from the motor to the Control Unit depends on the type
of signal cable being used.
Because of EMC influence occurring on drive systems, we always recommend that shielded
cables are used.
Cables subject to high acceleration rates can wear more quickly. The cables permanently
connected to the motor cannot be replaced if they are damaged.
• Observe the permissible acceleration rates for the cables.
• Do not use a cable carrier for the cables permanently attached to the motor.
You will find MOTION-CONNECT cables from the terminal box provided by the customer or
extensions for the power and signal connection in the catalog.
General notes for routing electric cables
Drives with linear motors are subject to a high dynamic load. It must be ensured that
vibration is not transferred to the connectors by suitably routing the cables or by providing
strain relief close to the connector (distance < 10 D
max
). D
max
is the maximum cable diameter
(see Catalog).
