POWER UP The drive will automatically start upon application of input
power. The drive MUST be wired for a two-wire start/stop
circuit (refer to Section 14.0 - CONTROL WIRING). The
start command MUST be present when power is applied for
this function to operate.
AUTO RE- The drive will automatically restart after a protective fault or
upon application of input power. As with the POWER-UP
option, a start command must be present for this function to
operate.
RE-BRAKE After a fault, the drive will apply DC braking equal to the DC
BRAKE setting for 15 seconds and then restart. This is done
to ensure the motor is stopped during the restart attempt, as
the drive will not start into a spinning motor.
NOTE 1: POWER UP, AUTO RE-, and RE-BRAKE settings are only active
when the drive is in REMOTE mode (see Parameter 30 - CONTROL).
NOTE 2: After a fault, the drive will attempt to restart five times, and if
unsuccessful, will shut down on a FAULT LOCKOUT. Every 15 minutes that
passes will decrement the restart counter by one. Therefore, 75 minutes after a
successful restart, the restart counter is fully reset, and the drive can once again
attempt five restarts.
NOTE 3: The drive WILL NOT restart after the following faults: CONTROL
and PWR SAG. Also, if an OUTPUT fault occurs below 1.5 Hz, only one restart
will be attempted, after a four minute delay. If unsuccessful, it will then trip into
FAULT LOCKOUT, which will require a manual reset. This is done to protect
the drive in case of a shorted motor.
26 STOP (STOP MODE)
This parameter selects whether the motor will COAST to a stop, or RAMP to a
stop, when the drive is given a stop command.
COAST When a stop command is given, the drive shuts off the output
to the motor, allowing it to coast to a stop. The time required
for the motor to stop is governed by the inertia of the driven
load.
RAMP When a stop command is given, the drive will decelerate the
motor to a stop over a period of time according to Parameter
9 - DECEL.
