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
This parameter determines how the reference or output of the drive is displayed. If User Units is selected, parameter
805
allows you to customize the 3 unit values on the display. The following data values may be used:
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 PID feedback input to an analog input
Fbk PSI
Display is scaled to read in PSI based on the PID feedback input to an analog input
Fbk GPM
Display is scaled to read in GPM based on the PID feedback input to an analog input
Fbk User
Display is scaled to read in User units (parameter
805
) based on PID feedback input to an analog
input
Vin1 User
An alphanumeric, 3-character value defined by the user.
Vin2 User
An alphanumeric, 3-character value defined by the user.
Cin User
An alphanumeric, 3-character value defined by the user.
809
(Display Scale)
references
time of operation when running at Max. Frequency. Example: 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 (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
Level 2, Macro
This parameter configures the language text strings will be displayed in. The following data values may be assigned:
Parameter Value
English
Spanish
