Commissioning
Speeds for making measurements as a function of the maximum speed p1082 are pre-
assigned in p382x when commissioning the drive system for the first time. These can be
appropriately changed corresponding to the actual requirements.
The automatic friction characteristic plot can be activated using p3845. The characteristic is
then plotted the next time that it is enabled.
The following settings are possible:
• p3845 = 0
• p3845 = 1
• p3845 = 2
• p3845 = 3
When the friction characteristic is plotted, the drive can cause the motor to move. As a
result, the motor may reach maximum speed.
When commissioning the drive, the EMERGENCY STOP functions must function perfectly.
To protect the machines and personnel, the relevant safety regulations must be observed.

Friction characteristic plot de-activated
Friction characteristic plot activated, all directions of rotation
The friction characteristic is plotted in both directions of rotation. The
result of the positive and negative measurement is averaged and
entered into p383x.
