4-43 Programming Reference
This parameter
selects whether the
start input is
edge-sensitive or
level-sensitive for
remote (P.000 = rE)
and option port
(P.000 = OP) control
sources.
P.054 Level Sense Start Enable
Parameter Range: OFF = Start input is edge-sensitive
ON = Start input is level-sensitive
Default Setting: OFF
Parameter Type: Configurable
Refer also to parameters: P.000 Control Source
ATTENTION: 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 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 terminal strip function loss input must be closed.
• No fault can be active.
• The DC bus must be valid.
• No active stop input can 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 closed.
