Rockwell Automation Liqui-Flo 1.5 General Purpose and Vector Duty - Manual (Page 63)

Parameter Descriptions 4-31
Present value of the PI error signal.
Present value of the PI output signal.
The Accel Time parameters set the rate at which the drive ramps to its output
frequency after a start command or during an increase in command frequency (speed
change). The rate established is the result of the following equation:
Maximum Frequency - Minimum Frequency / Accel Time = Accel Rate
Two accel times exist to enable acceleration rate changes “on the fly” using a building
automation system command, digital input, or F-Key on the LCD OIM, if configured
(see chapter 2).
