Rockwell Automation 1336S Plus FRN 1.xx-5.xx - Manual (Page 44)

2–34 Installation/Wiring
Drive Output Disconnection
!
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.
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.

Optional Cable Terminator
Voltage doubling at motor terminals, known as reflected wave
phenomenon, 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.
