The Display Mode parameter determines how the reference or output of the drive will be
displayed to the user. If User Units is selected, parameter 805 allows you to customize
the 3 unit values on the display. The following data values may be assigned to this param-
eter:
Parameter Value Description
Std Disply Standard commanded frequency
Out Freq Output frequency actually sent to the motor
Stator Freq Frequency of the stator
User Units Custom units display based on values in parameter 805
RPM Units Custom speed display with RPM as units
GPM Units Custom speed display with GPM as units
FPM Units Custom speed display with FPM as units
MPM Units Custom speed display with MPM as units
PSI Units Custom speed display with PSI as units
Degrees C Custom display with degrees C
Degrees F Custom display with degrees F
Time hrs Custom display time in hours of operation
Time min Custom display time in minutes of operation
Time sec Custom display time in seconds of operation
Fbk RPM Display is scaled to read in RPM based on the PI feedback in-
put to an analog input
Fbk PSI Display is scaled to read in PSI based on the PI feedback input
to an analog input
Fbk GPM Display is scaled to read in GPM based on the PI feedback in-
put to an analog input
Fbk User Display is scaled to read in User units (parameter 805) based
on PI feedback input to an analog input
When using any of the Time functions, these refer to “Retention Time.” Retention time is
an inverse function: as speed goes up, time goes down, and vice versa. It is typically used
in oven-type applications. The value set in parameter 809 (Display Scale) references the
time of operation when running at Max. Frequency. For instance, if parameter 302 (Max.
Frequency) is set for 60 Hz, 804 (Display Mode) is set for Time min, and 809 (Display Scale)
is set for 600, the scales of the display will read 60.0 min at maximum speed and increase
in time (in minutes) up to the maximum scale of 6553.5 at minimum frequency.
This parameter determines the three-character customer display units used when pa-
rameter 804 is set to User Units. The last digit indicates the number of decimal places to
be shown on the display. Up to three decimal places are possible.
This parameter determines how the reference or output of the drive will be displayed to
the user. It selects the maximum scaling of the display when running at maximum fre-
quency.
