9.4.37 Displacement angle setting [841]
The position of the slave axis can be corrected by a displacement value
through the absolute displacement angle. This value can be preset by
parameter U677 or connector (U678.01). This displacement angle acts
absolutely i.e. it resets all displacement or offset movements that have
been previously effected by other displacement angle settings and
which have accumulated in the "Current displacement" signal [841.8].
The absolute displacement is set once in each case when the value of
the "absolute displacement angle" is changed via the "Compensation
movement" function [841.7] with adjustable differential speed and
acceleration. In the startup process, the displacement angle is set to 0.
The first change at the connector input results in a new setting of the
displacement angle.
You can select via operating mode U699.2 whether the compensation
movement of the axis is to take place in the specified direction (i.e.
clockwise if displacement is changed to a higher value, and counter-
clockwise if displacement is changed to a lower value), or via the
shortest route (e.g. correction from 350° to 10°, by 20° clockwise, not
by 340° counter-clockwise).
The currently valid displacement angle can be changed via the relative
displacement angle (U678.3) by the specified value. This is activated by
two binectors for adjusting in the positive direction (U694.1) and in the
negative direction (U694.2). The change is adopted at these control
inputs with each positive edge.
The relative displacement angle Δs_relative can be greater than the
parameterized slave axis length.
The displacement is set via the "Compensation movement [841.7] with
an adjustable ramp and differential speed.
The current displacement angle can be changed via the two binectors
Inching+ (U696.1) and Inching– (U696.2). The variable speed and
acceleration can be set via U695.2 and .3. Adjustments can be made
as long as one of the two inputs is activated. No adjustment is made if
both inputs are activated simultaneously.
The resulting displacement angle is output as "modulo axis cycle
length" at connector KK812, i.e. the displacement angle refers to an
axis cycle. The displacement angle can be assigned to a
tracking/storage element [760] for data remanence and, once the
MASTERDRIVES electronics power supply has been restored, can be
stored again as a set value by the tracking/storage element.
