Description: Sets the signal sources for friction compensation.
Index: [0] = Signed
[1] = Absolute
Note: The signals in p50519[0] and p50519[1] are summed and applied to the friction compensation input.
Description: Sets friction compensation at 0 % speed.
Recommendation: In the case of operation in both directions of rotation, this basic value should be set to 0% to prevent the armature
current from oscillating.
Note: The basic values are based on the device rated direct current or the device rated torque.
The basic values for friction compensation (p50520 ... p50530) are set automatically during the optimization run for
friction compensation (p50051 = 28).
There is linear interpolation between the basic values; here, the friction compensation value takes on the input
signal's sign.
Description: Sets friction compensation at 10 % speed.
Description: Sets friction compensation at 20 % speed.
