Friction Compensation; P519 Source For Input Signal Of The Friction Compensation [Sw 2.0 And Later]; P520 Friction At 0% Speed; P530 Friction At 100% Speed And Higher - Siemens 6RA70 Series Instructions Manual

PNU Description

10.29 Friction compensation

(see also Section 8, Sheet G153 of Operating Instructions 6RX1700-0AD**)
Parameters P520 to P530 are the armature current and torque setpoint required for a stationary input signal (factory setting: speed
controller actual value K0179) of 0%, 10% to 100% of the maximum value (in steps of 10%).
These parameters are intermediate points along the friction curve. Depending on P170 (0 or 1) they are either an armature current or a
torque setpoint and are set automatically when the friction and moment of inertia compensation (P051=28) are optimized. P520 is then set
to 0.0%.
The intermediate points are interpolated linearly during which the output of the friction compensation assumes the sign of the input signal.
P530 is specified by the friction compensation even for input signals >100% of the maximum signal.
During operation in both directions we recommend leaving P520 at 0.0% in order to avoid armature current vibration at 0% of the input
signal.
