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.
