Figure 4-1 Minimum and maximum motor frequency
CAUTION
Material damage caused by the motor unexpectedly accelerating
Depending on the particular Power Module, the inverter sets the minimum frequency p1080
to 20% of the maximum frequency. Also for a setpoint = 0, for p1080 > 0, after the motor is
switched on it accelerates to the minimum frequency. Material damage can occur if the
motor unexpectedly accelerates.
• If the application requires a minimum frequency = 0, then set p1080 = 0.
Scaling of analog input 0

Motor data identification: Select the method which the inverter uses to measure the data of
the connected motor:
● OFF: Motor data is not measured.
● STIL ROT: Recommended setting: Measure the motor data at standstill and with the
motor rotating. The inverter switches off the motor after the motor data identification has
been completed.
