Rockwell Automation Liqui-Flo AC GP Vector Drive Version 6.4 - Manual (Page 113)

Programming Reference 4-31
For vector regulation, P.028 will correspond to U.017:
Actual Speed in RPM x P.028 = value displayed when SPEED monitor mode or
U.017 selected reference is selected.
P.028 Speed Display Scaling (continued)
For V/Hz regulation, P.028 will correspond to H.001:
Actual Speed in Hz x P.028 = value displayed when SPEED monitor mode
H.001 or selected reference is selected
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 = P.003 x P.028 Maximum reference = P.004 x P.028
U.017 U.017
P.028 Speed Display Scaling
This parameter
defines the scaling
value applied to the
manual reference,
the selected speed
reference, and the
output speed
displays. Parameter Range: 10 to 9999
Default Setting: Synchronous speed based on H.001 (assuming a
4-pole motor) (V/Hz)
U.017 (vector)
Parameter Type: Tunable
