Checking the compatibility of the motor and drive

Check that the 3-phase AC induction motor and the drive are compatible according
to the rating table in section
power for each drive type.

Selecting the power cables

General rules

Dimension the input power and motor cables according to local regulations.
• The input power and the motor cables must be able to carry the corresponding
load currents. See section
• The cable must be rated for at least 70
the conductor in continuous use. For US, see section
on page 32.
• The conductivity of the PE conductor must be equal to that of the phase
conductor (same cross-sectional area).
• 600 V AC cable is accepted for up to 500 V AC.
• Refer to chapter
A symmetrical shielded motor cable (see the following figure) must be used to meet
the EMC requirements of the CE and C-Tick marks.
A four-conductor system is allowed for input cabling, but a shielded symmetrical
cable is recommended.
Compared to a four-conductor system, the use of a symmetrical shielded cable
reduces electromagnetic emission of the whole drive system as well as motor
bearing currents and wear.
