803 PWM Frequency Default: 3.0 kHz
Range: 0.6-16.0 kHz
Level 2
The PWM Carrier Frequency parameter sets the carrier frequency of the Pulse-Width Modulation (PWM)
waveform supplied to the motor. Low carrier frequencies provide better low-end torque, but produce some
audible noise from the motor. Higher carrier frequencies produce less audible noise, but cause more
heating in the drive and motor.
804 Display Mode Default: Std Disply
Range: n/a
Level 2
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 parameter:
Parameter Value Description
Std DisplyStandard commanded frequency
Out FreqOutput frequency actually sent to the motor
Stator FreqFrequency of the stator
User UnitsCustom units display based on values in parameter 805
RPM UnitsCustom speed display with RPM as units
GPM UnitsCustom speed display with GPM as units
FPM UnitsCustom speed display with FPM as units
MPM UnitsCustom speed display with MPM as units
PSI UnitsCustom speed display with PSI as units
Degrees CCustom display with degrees C
Degrees FCustom display with degrees F
Time hrsCustom display time in hours of operation
Time minCustom display time in minutes of operation
Time secCustom display time in seconds of operation
Fbk RPMDisplay is scaled to read in RPM based on the PID feedback input to an analog input
Fbk PSIDisplay is scaled to read in PSI based on the PID feedback input to an analog input
Fbk GPMDisplay is scaled to read in GPM based on the PID feedback input to an analog input
Fbk UserDisplay is scaled to read in User units (parameter 805) based on PID feedback input to an analog input
Vin1 UserAn alphanumeric, 3-character value defined by the user.
Vin2 UserAn alphanumeric, 3-character value defined by the user.
Cin UserAn alphanumeric, 3-character value defined by the user.
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.
805 Display Units
Default: RPM: 1
Range: n/a
Level 2
This parameter determines the three-character customer display units used when parameter 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.
809 Display Scale Default: 18000
Range: 1-32767
Level 2
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 frequency.
810 Language Default: English
Range: 1-65535
