Common Mode Cores
Common Mode Cores will help reduce the common mode noise at the
drive output and guard against interference with other electrical
equipment (programmable controllers, sensors, analog circuits, etc.).
In addition, reducing the PWM carrier frequency will reduce the
effects and lower the risk of common mode noise interference. Refer
to the table below.

PLUS II Common Mode Chokes
Cable Termination Optional Cable Terminator
Voltage doubling at motor terminals, known as reflected wave phe-
nomenon, standing wave or transmission line effect, can occur when
using drives with long motor cables.
Inverter duty motors with phase-to-phase insulation ratings of 1200
volts or higher should be used to minimize effects of reflected wave
on motor insulation life.
Applications with non-inverter duty motors or any motor with excep-
tionally long leads may require an output filter or cable terminator. A
filter or terminator will help limit reflection to the motor, to levels
which are less than the motor insulation rating.
!
ATTENTION: Any disconnecting means wired to the drive
output terminals U, V and W must be capable of disabling
the drive if opened during drive operation. If opened during
drive operation, the drive will continue to produce output
voltage between U, V, W. An auxiliary contact must be used
to simultaneously disable the drive.
