Advanced commissioning

6.5 Motor control
To record the friction characteristic, proceed as follows:
1. Set P3845 = 1: The inverter accelerates the motor successively in both directions of
rotation and averages the measurement results of the positive and negative directions.
2. Switch on the motor (ON/OFF1 = 1).
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.

Explanation
Intermediate points of the friction characteristic [rpm; Nm]
Friction characteristic status word
.00 1 signal: Friction characteristic OK
.01 1 signal: Determination of the friction characteristic is active
.02 1 signal: Determination of the friction characteristic is complete
.03 1 signal: Determination of the friction characteristic has been aborted
.08 1 signal: Friction characteristic positive direction
Friction characteristic, output [Nm]
Activate friction characteristic
0: Friction characteristic deactivated
1: Friction characteristic activated
Activate friction characteristic plot (factory setting: 0)
0: Friction characteristic plot deactivated
1: Friction characteristic plot activated, both directions
2: Friction characteristic plot activated, positive direction
3: Friction characteristic plot activated, negative direction
To interconnect the precontrol of the speed
controller with the frictional torque, set p1513
= r3841 (frictional torque = additional torque
2).
