Description:
Be aware of the following before enabling this function:
Setting this parameter to ON immediately applies output power to the motor when all start
conditions are met.
If the drive is running from the terminal strip, both the start and stop inputs are closed. If P.054 =
ON and a fault occurs, the drive coasts to rest and generates a fault. In this case, resetting and
clearing the fault immediately restarts the drive without any change to the start or stop input
states.
If P.026 (Function Loss Response) = 1, the control source is the terminal strip (start and stop
inputs are closed), and P.054 = ON, the drive coasts to rest if the function loss input is opened
and does not generate a fault. In this case, closing the function loss input immediately starts the
drive without any change to the start or stop input.
When this function is enabled, the user must ensure that automatic start up of the driven equipment
will not cause injury to operating personnel or damage to the driven equipment. In addition, the user
is responsible for providing suitable audible or visual alarms or other devices to indicate that this
function is enabled and the drive may start at any moment. Failure to observe this precaution could
result in severe bodily injury or loss of life.
This parameter applies to remote (P.000 = rE) and option port (P.000 = OP) control sources only.
Local keypad (P.000 = LOCL) and serial port (P.000 = SErL) control sources always require an off-to-
on edge on the start input to start the drive.
Regardless of the status of P.054, the following conditions must be met in order for the drive to start.
• The function loss input (terminal 20) must be closed.
• No faults must be active.
• The DC bus must be valid.
• No active stop input must be asserted.
When P.054 is set to OFF, and the above requirements are met, the drive requires an off-to-on edge
at the start input in order to start.
When P.054 is set to ON, and the above requirements are met, the drive applies output power to the
motor when the start input is asserted.
