Present value of the process PI feedback signal.
Present value of the process PI error signal.
Present value of the process 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, if configured (see Appendix B).
