100 Rockwell Automation Publication D2-3518-4 - January 2020
Chapter 9 Parameter Descriptions
• Is set to 1 to indicate when the PI output equals positive limit or negative
limit.
Present value of the PI reference signal.
Present value of the PI feedback signal.
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 Speed ÷ Accel Time) = Accel Rate
