Issue:
Multiple motor leads wired in the same conduit in a VFD installation.
Product Line:
All Altivars
Environment:
All
Cause:
Multiple motor and or Line leads from different drives in the same conduit.
Resolution:
It is not recommended to run the motor leads from different drives in the same conduit.
Multiple motor leads from different drives is not recommended because the noise generated from the pulse width modulated (PWM) waveform can cause cross-talk resulting in possible nuisance tripping.
