10-14 Parameter Definitions MN448
Parameters in the Long parameter mode
No.
Name/Value Description Default
32 SUPERVISION Signal supervision. The drive monitors whether certain user selectable
variables are within the user-defined limits. The user may set limits for
speed, current etc. Supervision status can be monitored with relay output.
See parameter group 14 RELAY OUTPUTS.

34 PANEL DISPLAY
Selection of actual signals to be displayed on the drives front panel e.g.
to display conveyer speed in meters per second based on the output
frequency.
3400 DISPLAY SCALING Allow the user to display an alternative output unit scaled from an existing
parameter. This function is disabled if 3400 = 0.000
Press the Navigate key briefly to switch between Index 1 and 2. Then use
the UP or DOWN arrow to adjust the value within each Index (Index 1 is
displayed first).

4001 PI PROPORTIONAL GAIN PI Controller Proportional Gain. Higher values provide a greater change in
the drive output frequency in response to small changes in the feedback
signal. Too high a value can cause instability

PI Controller Integral Time. Larger values provide a more damped response
for systems where the overall process responds slowly

0.0…30.0 S
0: DIRECT OPERATION Use this mode if an increase in the motor speed should result in an increase
in the feedback signal
1: INVERSE OPERATION Use this mode if an increase in the motor speed should result in a decrease
in the feedback signal
