N O T I C E
The measurements in the following tables are carried out with a single power size and motor, but with several motor cable
lengths, are for information only. Depending on the combination of drive, motor cable type, motor cable length, and motor, the
values for Upeak and dU/dt can be higher at the motor terminal. Sometimes, the values exceed the limits given by the motor
manufacturer.
To avoid problems with too high dU/dt, use motor cables longer than 30–40 m (98–131 ft).
If in doubt, use a dU/dt filter between the drive and the motor, or do a measurement in the actual installation.
10.15 Electromagnetic Compatibility (EMC) Overview
10.15.1 EMC Test Results
The following test results have been obtained by using a system with a drive, a shielded control cable, a control box with potentiom-
eter, a single motor, and shielded motor cable (Ölflex Classic 100 CY) at nominal switching frequency. See
for the maximum
motor cable lengths for compliance.
