The PLC is informed of which axes have been assigned via the NC/PLC interface. If the PLC
is controlling the oscillation axis, it must now also monitor the infeed axes and use the
signals for the infeed axes to generate the reactions on the oscillation axis via 2 stop bits of
the interface.
Application
The axes whose response has already been defined by synchronous conditions are
assigned to one another for activation of oscillation mode. The oscillation movement is
started.
Programming
OSCILL[oscillation axis] = (infeed axis1, infeed axis2, infeed axis3)
Infeed axis2 and infeed axis3 in brackets plus their delimiters can be omitted if they are not
required.
11.3.8 Definition of infeeds POSP
Function
The control receives the following data for the infeed axis:
● Total infeed
● Part infeed at reversal point/reversal point range
● Part infeed response at end
Application
This instruction must be given after activation of oscillation with OSCILL to inform the
controller of the required infeed values at the reversal points/reversal point ranges.
Programming
POSP[infeed axis] = (end position, part section, mode)
End position: End position for the infeed axis after all partial infeeds have been traversed.
Part section: Part infeed at reversal point/reversal point range
Mode 0: For the last two part steps, the remaining path up to the target point is divided into
two equally large residual steps (default setting).
Mode 1: The part length is adjusted such that the total of all calculated part lengths
corresponds exactly to the path up to the target point.
