Note: P1055 = 0 and P1056 = 0 ==> Total frequency setpoint is selected.
P1080[0...2] Minimum frequency [Hz] 0.00 -
599.00
0.00 C(1), U, T - DDS Float 1
Sets minimum motor frequency at which motor will run irrespective of frequency setpoint. The minimum
frequency P1080 represents a masking frequency of 0 Hz for all frequency target value sources e.g. AI,
MOP, FF, USS with the exception of the JOG target value source (analogous to P1091). Thus the
frequency band + / -P1080 is run through in optimum time by means of the acceleration / deceleration
ramps. Dwelling in the frequency band is not possible. Furthermore, an overshoot of the actual frequency
f_act upper minimum frequency P1080 is output by the signal function |f_act| > f_min.
Note: Value set here is valid both for clockwise and for anticlockwise rotation.
Under certain conditions (e.g. ramping, current limiting), motor can run below minimum frequency.
P1082[0...2] Maximum frequency [Hz] 0.00 -
599.00
50.00 C(1), T - DDS Float 1
Sets maximum motor frequency at which motor will run irrespective of the frequency setpoint. The value
set here is valid for both clockwise and anticlockwise rotation.
Furthermore, the monitoring function |f_act| >= P1082 (r0052 bit 10, see example below) is affected by this
parameter.

The maximum value of P1082 also depends on the nominal frequency: Max. P1082 = min (15*P0310,
599.0 Hz). As consequence P1082 can be affected if P0310 is changed to a smaller value. The maximum
frequency and the pulse frequency depending on each other. The maximum frequency affects the pulse
frequency according to the following table.
P1800
2 kHz 4 kHz 6 kHz 8 - 16 kHz
f
max
P1082 0 - 133.3 Hz 0 - 266.6 Hz 0 - 400 Hz 0 - 599.0 Hz
Dependency:
Example:
If P1082 is set to 350 Hz a pulse frequency from at least 6 kHz is necessary. If P1800 is smaller than 6
kHz the parameter is changed P1800 = 6 kHz.
The maximum output frequency of inverter can be exceeded if one of the following is active:
