Cabling is ubiquitous and critical. A poorly specified cable connecting the VSD/VFD to the motor can significantly degrade system performance. Other elements like braking resistors, filters and reactors vary from installation to installation, and can be very important to a successful deployment.
For example, some systems operate in areas where it’s necessary to control electromagnetic interference (EMI) and can benefit from using line filters that meet EN 61800-3 Category C2. Applications where rapid deceleration is required will need braking resistors. Line reactors can improve the power factor and boost efficiency, and output reactors can enable the use of longer cables.
