4.2.5.4 Motor cable length for parallel operation of motors

The resulting motor cable length for parallel operation of motors, or parallel installation

with multiple cables arises from the following formula:

resulting motor cable length = ∑single line length x √Number of motor lines

The cable cross-section of the motor cable depends on the real effective value of the

motor current, the line length, the type of the used cable (observe the manufacturer's

specifications) as well as the ambient conditions such as bundling and temperature.

Also observe the electrical regulations applicable for the operation site.

ATTENTION

Incorrect behavior of the motor!

► The connecting-up instructions of the motor manufacturer are al-

ways generally valid !

Protect motor against voltage peaks !

► Drive converters switch at the output with high dv/dt. Voltage peaks

that endanger the insulation system at the motor can occur espe-

cially in case of long motor cables (>15 m). A motor choke, a dv/

dt-filter or sine-wave filter can be used to protect the motor with

regard to the operating mode.
