Motor Start/Stop
Precautions

Mounting

ATTENTION: A contactor or other device that routinely
!
disconnects and reapplies the AC line to the drive to start and stop
the motor can cause drive hardware damage. The drive is designed
to use control input signals that will start and stop the motor. If an
input device is used occasionally, an auxiliary contact on that
device should also be wired to a digital input programmed as a
"Stop" function.
ATTENTION: The drive start/stop control circuitry includes
! solidstate components. If hazards due to accidental contact with
moving machinery or unintentional flow of liquid, gas or solids
exist, an additional hardwired stop circuit may be required to
remove the AC line to the drive. When the AC line is removed,
there will be a loss of any inherent regenerative braking effect that
might be present - the motor will coast to a stop. An auxiliary
braking method may be required.
Refer to the User Manual for Mounting Clearances. Drive mounting
dimensions are presented in Chapter 1.
