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. Always
follow local regulations.
Note: If the recommendations given by ABB are not followed, the drive may
experience problems that the warranty does not cover.

To Which Products this Chapter Applies

This chapter applies to the ACS800-01/U1, ACS800-02/U2, ACS800-04/U4,
ACS800-PC, and ACS800-07/U7 types up to -0610-X.

Motor Selection and Compatibility

1. Select the motor according to the rating tables in chapter Technical Data. Use the
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
0 ... 2 · I
3. Check that the motor voltage rating meets the application requirements:
• The motor voltage is selected according to the AC voltage feeding the drive when
the drive is equipped with a diode input bridge (a non-regenerative drive) and will
operate in motor mode (i.e. no braking).
• The motor nominal voltage is selected according to "the equivalent AC power
source voltage of the drive" if the intermediate DC circuit voltage of the drive is
increased from the nominal level by resistor braking or by the control program of a
regenerative IGBT line-side converter (parameter selectable function).
The equivalent AC power source voltage for the drive is calculated as follows:
U
