Planning the electrical installation

What this chapter contains

This chapter contains the instructions that you must follow when selecting the motor,
cables, protections, cable routing and way of operation for the drive system.
Note: The installation must always be designed and made according to applicable
local laws and regulations. ABB does not assume any liability whatsoever for any
installation which breaches the local laws and/or other regulations. Furthermore, if
the recommendations given by ABB are not followed, the drive may experience
problems that the warranty does not cover.

Motor selection and compatibility

1. Select the motor according to the rating tables in chapter
DriveSize PC tool if the default load cycles are not applicable.
2. Check that the motor ratings lie within the allowed ranges of the drive control
program:
• motor nominal voltage is 1/2 ... 2 · U
• motor nominal current is 1/6 ... 2 · I
3. Check that the motor voltage rating meets the application requirements:
• If no resistor braking is in use, the motor voltage rating is
• If frequent or long term brake cycles will be used, the motor voltage rating is
4. Consult the motor manufacturer before using a motor in a drive system where the
motor nominal voltage differs from the AC power source voltage.
