Function:
This parameter starts the PID autotuning sequence. Once the autotuning
has successfully completed and the settings have been accepted or re-
jected by the user, by pressing [OK] or [Cancel] buttons on the keypad at
the end of tuning, this parameter is reset to [0] Disabled.
Function:
Normal [0] causes the frequency converter's output frequency to de-
crease when the feedback is greater than the setpoint reference. This is
common for pressure-controlled supply fan and pump applications.
Inverse [1] causes the frequency converter's output frequency to in-
crease when the feedback is greater than the setpoint reference. This is
common for temperature-controlled cooling applications, such as cool-
ing towers.
Function:
When the frequency converter is first started, it initially ramps up to this
output speed in Open Loop Mode, following the active Ramp Up Time.
When the output speed programd here is reached, the frequency con-
verter will automatically switch to Closed Loop Mode and the PID Con-
troller will begin to function. This is useful in applications in which the
driven load must first quickly accelerate to a minimum speed when it is
started.
This parameter will only be visible if par. 0-02
RPM.
