Parameters Associated with Master / Slave Axes
TSX CAY •2: Link between Master and Slave Axes
A ratio and an offset define the link between the master axis and the slave axis.
ConsignePositionEsclave = PositionMaître x (Ratio1 / Ratio2)
+ SlaveOffset
If the slave is an infinite type machine, the Modulo operator is applied in the calculations of the slave position setpoint. Modulo value: ModuloValue is defined by
%Mdxy.i.33.
TSX CAY •2:
Ratio
TSX CAY •2:
Offset
TSX CAY •1
The ratio defined by: Ratio = Ratio1 / Ratio2 is adjustable.
Dynamic ratio values are set between 0.01 and 100. The ratio can be negative.
The SlaveOffset parameter corresponds to the position offset value between master and slave.
If the SlaveOffset parameter is zero, the slave axis setpoint = Ratio x master axis
Setpoint or Measurement.
The offset value must be between -2
30-1
and 2
30-1
and the resulting ConsignePositionEsclave parameter must stay within the software limits of the slave.
TSX CAY •1 modules are used to carry out master / slave applications, with nonmodifiable ratio, and without offset shift.
Note: In the case of 2 infinite axes (master and slave):
Modulo
Master x Ratio = Modulo
Slave
x k where k = whole number k represents the number of revolutions made by the slave in the time taken for the master to make one revolution.
