70 Rockwell Automation Publication 520-UM001K-EN-E - August 2021
Chapter 3 Programming and Parameters
Some parameters are marked as follows.
32-bit Parameters
Parameters marked 32-bit will have two parameter numbers when using RS485
communications and programming software. For example, parameters b010
[Process Display] and b011 [Process Fract] are scaled and displayed as follows.
• P043 [Minimum Freq] = 0 Hz
• P044 [Maximum Freq] = 60 Hz
• A481 [Process Display Lo] = 0
• A482 [Process Display Hi] = 10
Using the formula
when the drive is running at 10 Hz, the Process Value will be 1.66.
On the drive LCD display, only parameter b010 [Process Display] is shown.
In Connected Components Workbench software, parameter b010 [Process
Display] and b011 [Process Fract] are shown separately.
= Stop drive before changing this parameter.
= 32 bit parameter.
= Parameter is specific to PowerFlex 525 drives only.
Scaled Process Value (PV) =
([Process Disp Hi] - [Process Disp Lo]) x ([Output Freq] - [Minimum Freqp])
[Maximum Freq] - [Minimum Freq]
