Reflected Wave Protection
The drive should be installed as close to the motor as possible. Installations with
long motor cables may require the addition of external devices to limit voltage
reflections at the motor (reflected wave phenomena). Refer to Reflected Wave in
"Wiring and Grounding Guide, (PWM) AC Drives, " publication
IN001.
The reflected wave data applies to all carrier frequencies 2...16 kHz.
For 240V ratings and lower, reflected wave effects do not need to be considered.
Output Disconnect
The drive is intended to be commanded by control input signals that will start
and stop the motor. A device that routinely disconnects then reapplies output
power to the motor for the purpose of starting and stopping the motor should
not be used. If it is necessary to disconnect power to the motor with the drive
outputting power, an auxiliary contact should be used to simultaneously disable
drive (Aux Fault or Coast to Stop).
