The input path setpoint [834.1] is already received from SIMOLINK
receive double word 1 KK7031 [150.6] with the factory setting
(U600.01 = 7031 and U606 = 0). The master value is therefore correctly
connected to the output of the virtual master axis - via the SIMOLINK
interface (see the section entitled "Communication with the
technology").
The master axis cycle length U601 [834.2] must be set to the same
value as the axis cycle length of the master axis, e.g. to U687 (see
[832.6] and section 16). The master axis cycle length is required by the
DVAL block in order to reproduce the "position saw-tooth signal" of the
master correctly.
Set the desired synchronization operation [OPERATION] in U602
[834.5]:
U602=0 ; Continuous operation with engaging/disengaging cycle
U602=1 ; Engaging cycle (see "Synchronization block" section)
U602=2 ; Disengaging cycle (see "Synchronization block")
Use U603 [836.4] to select the desired synchronization function
[FUNCTION]:
U603=0 ; Angular synchronization 1:1
U603=1 ; Gear synchronization, gearbox: see [834.4]
U603=2 ; Electronic cam/table synchronization
; (see [839])
For rotary axes, you normally set the number of LUs per position
encoder revolution of the slave axis as the slave axis cycle length in
U501.11 (MD11 [836.5 + 7]). MD11 is required in order to generate the
correct "position setpoint saw-tooth signal" for the slave with the IVAL
block [836.7] and the corresponding "actual position saw-tooth signal"
with the actual position correction block KOR [836.8], in order to
prevent overflows in the numeric range for a rotary axis.
You only need to modify further parameters for the position correction
[836] if you use the printing index correction or want to evaluate a
synchronization signal.
You will find detailed information on the parameters for position
correction in the "Synchronization functions" chapter of the
Function Description in manual /1/.
