Chapter 1
Installation/Wiring
Other types of shielded cable are available, but the selection of these types may
limit the allowable cable length. Particularly, some of the newer cables twist 4
conductors of THHN wire and wrap them tightly with a foil shield. This
construction can greatly increase the cable charging current required and
reduce the overall drive performance. Unless specified in the individual
distance tables as tested with the drive, these cables are not recommended and
their performance against the lead length limits supplied is not known.
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). See
for
recommendations.
The reflected wave data applies to all frequencies 2 to 10 kHz.
For 240V ratings, 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
