P.028 Speed Display Scaling (continued)
For V/Hz regulation, P.028 will correspond to H.001:
Actual Speed in Hz x P.028
H.001
Note that the values entered for P.003 and P.004 are automatically converted to
P.028 units by the system. Therefore, the adjustment range for the manual
reference is limited as follows:
For vector regulation:
Minimum reference = Maximum reference =
For V/Hz regulation:
Minimum reference = Maximum reference =
V/Hz Speed Display Scaling Example
Your application requires the display to be scaled to show the speed reference or
the output speed as 800 gallons/minute when operating at maximum speed.
H.001 (Motor Nameplate Base Frequency) = 60
Step 1. Set parameter P.028 = 800
Step 2. Enter SPEED monitor mode by pressing the PROGRAM key until the
PROGRAM LED turns off and the SPEED LED turns on.
Step 3. Start the drive (press the START key).
Step 4. When the drive is running at half of rated speed, the display shows that
speed is 400 (gallons/minute).
Using the equation for V/Hz regulation: 30 x 800
60
= value displayed when SPEED monitor mode or
selected reference is selected.

Important: This parameter does not change the speed. It changes only the scaling
value applied to the display.
