Advanced commissioning
7.5 Motor control
3. The inverter accelerates the motor.
During measurement, the inverter signals the warning A07961.
When the inverter has determined all the intermediate points of the friction characteristic
without fault code F07963, the inverter stops the motor.
You have recorded the friction characteristic.
Interconnect the precontrol of the speed controller with the frictional torque
To interconnect the precontrol of the speed co
n-
troller with the frictional torque, set p1
513 =
r3841 (frictional torque = additional torque 2).
You will find additional information in function

Friction characteristic plot ramp-up/ramp-down time
(factory setting: 10 s)
Ramp-up/ramp-down time for automatic plotting of the friction characteristic.
p3847
Friction characteristic plot warm-up period
(factory setting: 0 s)
At the start of automatic plotting, the inverter accelerates the motor up to the speed =
p3829 und keeps the speed constant for this time.
