Outputs
Parameter
dnStartPos_p
DINT
Starting position in [inc] with which the integrator is loaded by setting
bLoadStartPos to TRUE.
• C05295 indicates the starting position in the real unit of the machine.
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)
Identifier/data type Value/meaning
dnPosOut_p
DINT
Master position output in [inc]
• Overflow is possible (display via bLimit)
• C05297 indicates the master position in the real unit of the machine.
dnSpeedOut_s
DINT
Master speed output in [rpm]
• C05298 indicates the master speed in the real unit of the machine.
bZero
BOOL
Status signal "Zero position/zero crossing"
FALSE Master value is at any position in the master value cycle (register)
TRUE Permanently:
Master value is at zero position.
For one cycle:
Zero crossing of the master value.
At the same time the status bit 10 ("Zero crossing active") is set in
C05299.
bError
BOOL
"Error" status
• The status signal can be reset to FALSE via bLoadStartPos if the error was caused
by a too great starting position at dnStartPos_p (see bit 16 in C05299).
TRUE An error has occurred (group signal).
• For details see display parameter C05299.
• bError can be reset to FALSE via bLoadStartPos if the error was
caused by a too great starting position at dnStartPos_p (see bit 16
in C05299).
