P03 START METHOD
WARNING!
Automatic starting of equipment may cause damage to equipment and/or
injury to personnel! Automatic start should only be used on equipment that is
inaccessible to personnel .
01 NORMAL: The drive will start when the appropriate contact is closed on the
terminal strip, or by pressing the START key on the optional remote keypad . Refer
to Parameter 14 .
02 START ON POWER UP: The drive will automatically start upon application of
input power .
03 START WITH DC BRAKE: When a START command is given, the drive will
apply DC BRAKE VOLTAGE (Parameter 22) for the duration of DC BRAKE
TIME (Parameter 21) prior to starting the motor to ensure that the motor is not
turning .
04 AUTO RESTART WITH DC BRAKING: Upon a START command, after a
fault, or upon application of power, the drive will apply DC BRAKE VOLTAGE
(Parameter 22) for the duration of DC BRAKE TIME (Parameter 21) prior to
starting (or restarting) the motor .
05 FLYING RESTART 1: Starts the speed search for the motor at MAXIMUM
FREQUENCY (Parameter 24) . This setting should be used if it is possible for
the load to increase speed after the drive trips or loses power .
06 FLYING RESTART 2: Starts the speed search for the motor at the last
frequency it was running at before the drive tripped on a fault or lost power .
The FLYING RESTART 1 and 2 settings allow the drive to start into a spinning load after
a fault or upon application of input power . Also, if STOP METHOD (Parameter 04) is set to
COAST (01), the drive will perform a flying start whenever it is started (except on application
of power) .
When programmed for auto-restart, the drive will attempt three restarts after a fault . The
interval between restart attempts is 15 seconds for setting 04, and 3 seconds for settings 05
and 06 . During the interval between restart attempts, the display will read “SP” to indicate
Start Pending . If all three restart attempts fail, the drive will trip into FAULT LOCKOUT
(displayed “LC”) and require a manual reset . Refer to Section 16 - TROUBLESHOOTING .
NOTE
Settings 02 and 04 - 06 require a two-wire start/stop circuit to operate . The RUN
contact must remain closed for the power-up start and auto-restart functions to
operate .
