34 SF01U
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. See 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: LOW performance. Slowest synchronization and lowest current
level. This setting results in the smoothest synchronization.
06 FLYING RESTART 2: MEDIUM performance. Faster synchronization and higher current
level. This setting allows faster synchronization while retaining smoothness.
07 FLYING RESTART 3: HIGH performance. Fastest synchronization and highest current
level. This setting allows the fastest synchronization, but sacrifices smoothness.
The FLYING RESTART 1 - 3 settings allow the drive to start into a spinning load after a fault
or upon application of input power. They differ in the time required to find the motor and the
amount of current required to synchronize with it. The faster the drive attempts to find the
motor, the more current is required.
When programmed for auto-restart (settings 04-07), the drive will attempt three restarts after
a fault. The interval between restart attempts is 15 seconds for setting 04, and 2 seconds for
settings 05, 06 and 07. 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 16.0 - TROUBLESHOOTING.
NOTE
Settings 02 and 04 - 07 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.
