5.90 L_LdLinearCoupling - master value connection
This FB serves as master value connection for the "Synchronism" application.
• The dnYSetPosCycle_p position value (Y cycle of the Y axis) is synchronous to the dnXPosIn_p
master value (cycle of the X axis), i.e. if the master value overflows, a new cycle also starts for
the dnYSetPosCycle_p output.
• The FB makes use of the set cycles of XAxisData and YAxisData. The transformation displays one
cycle of the X axis exactly with residual values in one cycle of the Y axis.
• Internal calculation:
dnYSetPosCycle = dnXPosIn_p * (cycle Y / cycle X)
Inputs
Function library: LenzeLineDrive
Runtime software licence:  Motion Control HighLevel  Motion Control TopLevel
Identifier/data type Information/possible settings
bEnable
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.
• The dnYSetPosCycle_p output is maintained on the last value.
Caution: Consequently, a position step change on the master value
end will not be displayed at the dnYSpeedOut_s and
dnYSetPosCycle_p outputs!
TRUE Function is activated.
bXReset
BOOL
Reset the master value selection dnXPosIn_p internally
FALSE Output corresponds to dnXPosIn_p + dnXOffset_p.
TRUE Master value selection dnXPosIn_p is internally set to and held at "0".
Output corresponds to dnXOffset_p.
dnXPosIn_p
DINT
Master value selection in [inc]
• C05186 indicates the master position in the real unit of the machine.
dnXOffset_p
DINT
Phase offset selection for the master value in [inc]
• The phase offset is applied immediately.
• C05187 indicates the phase offset in the real unit of the machine.
XAxisData Machine parameters for scaling the master value
• The machine parameters of a master drive can be displayed with the
FB L_SdSetAxisData . In this case, the FB output AxisData must be connected to
this input. ( 510)
YAxisData Machine parameters for scaling the setpoint
• For accepting the machine parameters of the drive/motor, connect this input
with the output DI_AxisData of the SB LS_DriveInterface.
