5.98 L_LdSyncOperation - master value connection
This FB implements synchronism between a master drive and a slave drive:
• Drift-free synchronism between master drive and slave drive (modulo measuring systems) with
different types of couplings.
• Additional in-cycle compensation of angular trimming in the master measuring system (x off-
set).
 Tip!
There are two other FB for synchronous operations:
•The L_LdConvAxisV
FB generates the speed setpoint for the following axis from the mas-
ter speed instead of the master position, as this FB does.
• Like this FB, the L_LdLinearCoupling
FB accepts an x position as the master value, but ge-
nerates a setpoint position for the following axis in addition to the setpoint speed.

BOOL
Activate function
FALSE Function has been deactivated.
•The dnXSpeedOut_s and dnXActPos_p outputs continue to follow
the dnXPosIn_p and dnXOffset_p input positions.
• A value of "0" is output at the dnYSpeedOut_s output.
Caution: Thus, a position step change at the master value end will
not be displayed at dnYSpeedOut_s!
TRUE Function is activated.
• According to the coupling mode parameterised in C05090, the
output signals follow the input positions, dnXPosIn_p and
dnXOffset_p.
