L_SdGetAxisData - Reading out machine parameters from axis data
This FB reads out selected machine parameters from the copied axis data and makes them available
to other FB which require them for internal calculations (e.g. master value integrators, FB for stret-
ching/compression, and other FB for the edition of cam data).
Inputs
Outputs
Function library:
LenzeServoDrive
FB is available as of library V02.07.xx.xx!

Identifier/data type
Information/possible settings
AxisData
Machine parameters
• For accepting the machine parameters of the drive/motor, connect this input
with the output DI_AxisData of the SB LS_DriveInterface.
• The machine parameters of a master drive can be displayed with the
FB
. In this case, the FB output AxisData must be connected to
this input.
Identifier/data type
Value/meaning
dnCycleLength_p
DINT
Cycle in [increments]
• C04416 indicates the cycle in the real unit of the machine.
dwCycleLengthRes
DWORD
Remainder of the cycle
dnFeedConstant
DINT
Feed constant in [increments]
• C04411 indicates the feed constant in the real unit of the machine.
dnReferenceSpeed_s
DINT
Reference speed as a speed signal
• Scaling: 2
26
≡ 15000 [rpm]
• C04420 indicates the reference speed in the real unit of the machine.
dnGearNumerator
DINT
Gearbox factor (numerator)
• The gearbox factor related to the current position control (C02570) and to the po-
sition encoder selection (C00490) is output.
• Display parameter: C04410/1
• C04424 indicates the resulting gearbox factor.
dnGearDenominator
DINT
Gearbox factor (denominator)
• The gearbox factor related to the current position control (C02570) and to the po-
sition encoder selection (C00490) is output.
• Display parameter: C04410/2
• C04424 indicates the resulting gearbox factor.
