Operation
If the inverter is set in an Auto Restart Mode and normal
operation is using input power to start and stop the motor, the
inverter may be started once every two minutes. The inverter will
prevent operation if more frequent starts are commanded using
line power connection.
Synchro Starts - The Synchro Starts feature is desirable in
applications where the motor shaft is rotating at the time that
power is supplied to the motor from the inverter. If enabled the
control will automatically sense the motor rotational frequency
and immediately output that frequency at start up.
WARNING: A lightly loaded motor may suddenly
accelerate before locking in the proper
speed. Ensure that this operation will not
cause injury to personnel or damage to
driven equipment.
