8.3 Cooler connection

NOTICE

With 1FW6 built-in torque motors featuring single-core power cables without a PE cable, a connection point is provided for the PE. A separate PE cable must be connected to this to ensure a direct connection to the power unit.

8.2.4Requirements for the motor supply cables

Motor supply cables

The length of the power and signal cables from the motor to the converter must not exceed 50 m.

NOTICE

The permissible acceleration rates of the cables must be carefully taken into consideration. In particular, this applies when the cables are routed via a tow chain.

To prevent wear and tear, the cables fixed permanently to the motor should not be routed via a tow chain because they cannot be replaced if they are damaged.

Also refer to integrating into the system. Data for the motor supply cables: see "Overview" and catalog NC 61.

MOTION-CONNECT cables from the terminal box provided by the customer or extensions for the power and signal connection: see catalog NC 61.

Specification of the motor supply cables

The built-in torque motors are shipped with MOTION-CONNECT cables in accordance with catalog NC 61, which contains the technical specifications:

Power cable: MOTION-CONNECT 800, type 6FX8

Signal cable: MOTION-CONNECT 700, type 6FX7

Cooler connection for motors with a cooling jacket

The cooler for motors with a cooling jacket is connected via the built-in construction. The cooling water cable cross-sections depend on the cross-sections of the cooling slots in the jacket. These slots are sealed by means of the housing provided by the customer and the O- rings.
