Outputs
Parameter
bLoadEncoderPos
BOOL
From library V01.03.xx.xx
Load integrator with absolute encoder position
• Application: Initialisation of output positions for absolute value encoders
TRUE Load integrator with encoder positions at the dnEncoderIn /
dnEncoderIn2 inputs
• The resolution of an encoder revolution set in the machine para-
meters (AxisData) will be considered here.
• Input signal changes still result in the generation of a speed value
at the output.
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 contained within the cam data can be read out via
L_CamGetAxisData FB. In this case the FB output AxisData must be connected to
this input. ( 155)
• 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)
• If this input is released, the following scaling applies:
1 motor revolution ≡ 2 16
Identifier/data type Value/meaning
dnPosOut_p
DINT
Master position output in [inc]
• Overflow is possible (display via bError)
• C05282 indicates the master position in the real unit of the machine.
dnSpeedOut_s
DINT
Master speed output in [rpm]
• C05283 indicates the master speed in the real unit of the machine.
bInit
BOOL
Status signal "Encoder initialisation phase active"
TRUE The initialisation time for the encoder set in C05277 has not elapsed
yet, the FB does not yet carry out internal calculations.
bError
BOOL
"Error" status
• Status signal can be reset via bLoadStartPos.
TRUE An error has occurred (group signal).
• For details see display parameter C05289.
Parameter Possible settings Information
C05270/1 String of digits Position unit
• Read only
C05270/2 String of digits Speed unit
• Read only
C05271
From library V01.03.xx.xx
Encoder position evaluation
0 32 bit encoder signal
• The 32 bit input position is trans-
mitted via the dnEncoderIn input.
• The resolution of the signal re-
sults from C05273 and C05274.
Lenze setting
1 64 bit encoder signal
• The 64 bit input position is trans-
mitted via the dnEnoderIn and
dnEncoderIn2 input.
• The resolution of the signal re-
sults from C05274.
