Figure 5-6 Minimum and maximum motor frequency
CAUTION
Material damage caused by unexpected acceleration of the motor
Depending on the Power Module, the inverter sets the minimum frequency p1080 to 20% of
the maximum frequency. Also for setpoint = 0, the motor accelerates for p1080 > 0 to the
minimum frequency after switching on the motor. An unexpected acceleration of the motor
can cause material damage.
● If the application requires a minimum frequency = 0, then set p1080 = 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.
● STILL: Measure the motor data at standstill. The inverter switches off the motor after the
motor data identification has been completed.
Select this setting if one of the following cases is applicable:
– You have selected control mode "SPD N EN", however, the motor cannot freely rotate
- for a mechanically limited travel range, for example.
– You have selected U/f control as control mode, e.g. "VF LIN" or "VF QUAD".
● ROT: Measure the motor data while the motor is rotating. The inverter switches off the
motor after the motor data identification has been completed.
