Compensation process
At the input of the second set or actual touch probe pulse, the difference between master and slave
position is detected which is then provided via the
nSpeedSetOut_v
speed output and equivalently
as position at .
In
, the following bit coded settings can be made for the compensation procedure:
The following illustration shows a compensating process after the marks have been detected. The
speed is added here as a parabola to the line speed. (The scaling in this diagram does not correspond
to reality)

Info
Bit 1
Angle correction with polynomial
If this bit is set (Lenze setting),the compensating movement is
rounded by polynomial.
• The angle error to be compensated is limited to ±1073741823
increments due to the system. This applies in general when the
L_DFSET_1
carries out the compensation.
• The maximum compensating speed can be set in
. When
, the angle error is
measured and output to
dnPosDiffOut_p
.
Bit 2
External angle correction
From version 13.00.00
If this bit is set, the FB
L_DFSET_1
does not compensate any angle
errors.
• Every time the angle errors have been measured, the angular
difference is output to
dnPosDiffOut_p
.
• In addition, a FALSE/TRUE edge is output to
bAck
. This signal
serves to trigger an external profile generator which
compensates the angular offset via a speed profile additionally.
