Sets the duration of an operation in seconds
from the time it it is initiated. At the end of
the period, the inverter will stop and wait for a
RUN command (FWD/REV-P24 = ON). If a
RUN command is removed before the timer
has timed out, the inverter output will stop,
see left-hand side of diagram above.
Setting ranges
0.00 = Inactive (Factory-set default)
from 0.01 to 9.99 in steps of 0.01
from 10.0 to 99.9in steps of 0.1
from 100 to 999in steps of 1
from 1000 to 3600 in steps of 10
Selects the type of output signal provided at
terminal Y1E from the following:
0 = RUN signal. Inverter active.
1 = Output frequency level detection (FDT,
refer to Function 55). Terminal output
is ON when the output frequency is
identical to the frequency set in
Function 55. Factory-set default.
2 = Output frequency equivalence signal
(FAR, refer to Function 56). Terminal
output is ON when the frequency reach-
es the frequency set by the keypad
panel, the analog input, or a preset
speed, plus or minus the hysteresis,
Function 56.
3 = Inverter undervoltage trip operated
(LU).
4 = Inverter torque limiting mode (TL).
5 = Auto-restart mode after momentary
power loss (IP).
Sets the frequency level in Hz at which the
FDT signal is activated during acceleration.
During deceleration the signal deactivates at
the FDT level minus the hysteresis set in
Function 56, as shown in the diagram above.
Factory-set default value is 50.00. Refer also
to Function 54, data setting 1.
Setting ranges
from 0.00 to 99.99 in steps of 0.01
from 100.0 to 400.0 steps of 0.1
Sets the hysteresis bandwidth for both the
FDT and the FAR Functions as shown in the
diagrams above. Setting range is 0 to 30Hz
in steps of 1Hz. Factory-set default 10Hz.
The frequency equivalence is at the mid-range
of the hysteresis setting.
Refer also to Function 54 data = 1 or 2.

WARNING For certain applications, eg lifts,
hoists etc, Functions 55 & 56 may be used
to de-energise a fail-safe electro-mechani-
cal brake system via output terminal Y1E.
It is essential that Function 56 is set cor-
rectly with respect to the required FDT
level, Function 55, prior to operation.
