Parameter Descriptions

12-37

Displays the present value of the process PI feedback signal.

Displays the present value of the process PI error signal.

Displays the present value of the process PI output signal.

PI Output

≈ PI Error x PI Prop Gain + PI Error/PI Integral Gain

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 network command, digital input, or F-Key on the LCD
OIM, if configured (see chapter 9 for information on configuring
F-Keys).
