TRQ LIM MSG
DLY
(Torque Limit Message Delay)
This
parameter determines the amount of time
the drive is in torque limit before the “HIT
TORQUE LIMIT” alarm message is
displayed.
sec 0.50 0.00 – 10.00
Y Y
ROLLBACK
GAIN
(Rollback Gain) This parameter increases
the sensitivity (or gain) of the speed
regulator during the start in the interval
between “Speed Regulator Release” and
“Reference Release”. The parameter acts
as a multiplier to the existing speed
regulator gain. For more information, see
ROLLBACK GAIN on page 37.
none 1 1 – 99
Y Y
NOTCH FILTER
FRQ
(Notch Filter Frequency)
Determines the
notch filter center frequency. For more
information, see NOTCH FILTER FRQ on
page 37.
Hz 20 5 – 60
Y Y
NOTCH FILT
DEPTH
(Notch Filter Depth) Determines notch
filter maximum attenuation.
Note: A filter depth setting of zero
(NOTCH FILT DEPTH (A1) = 0) removes
the filter.
% 0 0 – 100
Y Y
STNDBY FLD
TIME
(Standby Field Delay Time)
Determines
the time the drive will continue to supply
Full Field current after stopping and
turning motor armature current control
OFF. Motor field current will drop to
standby amps after this time delay.
sec 30 0 – 999
Y Y
DSPR TIME
(Drive Standby Power Reduction Time)
Determines how long the drive will remain
energized with motor field current at
Standby amps before progressing to
complete drive shutdown and utility side
disconnection. Only used when DPSR
ENABLE (C1) is set to ENABLE
min 120 0 – 999
Y Y
FULL FIELD
TIME
(Full Field Time) Determines the
maximum time the drive can remain at Full
Field without actually running. If logically
held in that condition for longer than the
Full field Time, a Fault will be declared to
prevent potential burnout of the motor
field.
