Parameter list
7.2 Parameter list
Parameter Function
Notice: P0503 = 1
Sets the following parameter values to minimize likelihood of a trip:
P0290 = 2 (inverter overload reaction: reduce pulse frequency, output current and output frequency)
•
P1210 = 7 (automatic restart function: restart after mains brown- /blackout or fault, trip when P1211
•
expires)
P1211 = 10 (number of times inverter will attempt to restart)
•
P1240 = 3 (configuration of Vdc controller: Vdc_max controller and kinetic buffering (KIB) enabled)
•
P0503 = 0
Resets the parameters to their default values:
P0290 = 2 (inverter overload reaction: reduce pulse frequency, output current and output frequency)
•
P1210 = 1 (automatic restart function: trip reset after power on, P1211 disabled)
•
P1211 = 3 (number of times inverter will attempt to restart)
•
P1240 = 1(configuration of Vdc controller: Vdc_max controller enabled)
•
Note: See also P0290, P1210, P1211, P1240, and P2113
P0507 Application macro
Selects a given Application macro, which is a set of parameter values for a given application. There are a
number of application macros covering a set of basic applications such as simple pump, conveyor, com-
pressor etc.
Note: Please note that to guarantee correct setting of the Application macro, the Application macro number
should only be changed during Setup directly after a parameter reset.
P0511[0...2] Scaling for display
Allows operator to enter the scaling factors for the display of motor frequency.
Index 0 = value of multiplier (a)
Index 1 = value of divisor (b)
Index 2 = value of constant (c)
With the parameter set to a non-default value the displayed value for frequency and setpoint on internal
and external BOPs is scaled accordingly. Note - the units "Hz" is no longer displayed if the value is scaled.
The formula used to scale the display is: (a / b)*N + c.

r0512 CO: Scaled filtered fre-
quency
Displays actual inverter output frequency (r0024) excluding slip compensation (and resonance damping,
frequency limitation in V/f mode).
P0604[0...2] Threshold motor tem-
perature [°C]
Enters warning threshold for motor temperature protection. The trip temperature defined is always 10 %
higher than the warning threshold P0604. When actual motor temperature exceeds warning temperature
then inverter reacts as defined in P0610.
Dependency: This value should be at least 40°C higher than the motor surrounding temperature P0625.
