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
Two accel times exist to enable acceleration rate changes on the fly using a
building automation system command or digital input, if configured.
