5.4 Quick commissioning using the BOP-2 operator panel
Select the default setting for the interfaces of the inverter that is suitable for your application.
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 a setpoint = 0, for p1080 > 0, after the motor is switched
on it accelerates to the minimum frequency. 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: No motor data identification
● 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: Default setting: Measure the motor data at standstill.
The inverter switches off the motor after the motor data identification has been completed.
Select this setting if the motor cannot freely rotate, e.g. for a mechanically limited traversing
range.
