Motor Start/Stop Precautions<br />
ATTENTION: A contactor or other device that routinely disconnects<br />
and reapplies the AC line to the drive to start and stop the motor can<br />
cause drive hardware damage. The drive is designed to use control input<br />
signals that will start and stop the motor. If used, the input device must<br />
not exceed one operation per minute or drive damage can occur.<br />
ATTENTION: The drive start/stop control circuitry includes<br />
solid-state components. If hazards due to accidental contact with<br />
moving machinery or unintentional flow of liquid, gas or solids exist,<br />
an additional hardwired stop circuit may be required to remove the AC<br />
line to the drive. When the AC line is removed, there will be a loss of<br />
any inherent regenerative braking effect that might be present - the<br />
motor will coast to a stop. An auxiliary braking method may be<br />
required.
