Scale factor display
Customer specific scaling factor.
With P-40 > 0
a “c” appears on the left hand side
of the display. With P-10 = 0 the scaling factor is
applied to the frequency, with P-10 > 0, to the
speed.
The value is displayed in real-time on the drives
display.

PI(D) controller proportional gain
Higher values will result in a larger change at the
frequency inverter output frequency as a response
to small changes in the feedback. Too high value
can cause instability

PID1 Control I Time
0.0 s
30.0 s
PI(D) controller integral time constant
Higher values will result in a more damped
response. Used in systems in which the overall
process responds slowly.

PID1 Mode
0
1
PI(D) controller 1 mode
0: direct mode. This setting is used when an
increase of the feedback signal should lead to a
decrease of the motor speed.
1: inverse mode. If an increasing feedback signal
should increase the speed of the motor, use
inverse mode.
