SOFT: V02.2X
Axes (2) controlled by a single drive
The mark for the secondary axis is SWITCH3 (M5205)
With SWITCH3=0 velocity command of the Z axis and with SWITCH3=1 that of the W axis.
PLC program
The M40 mark indicates that there is no external emergency (I1) and that the position loop of the
axes are closed (NOT LOPEN).
I1 AND NOT LOPEN = M40
An external switch (I12) turns the reciprocating movement off, PLC execution channel, and to switch
to the main execution channel (M41=1).
To switch from the PLC execution channel to the CNC channel, the PLC channel must be interrupted
(PLCABORT) and one must make sure that the axis has stopped (INPOS3)
I12 AND (other conditions) = SET PLCABORT = SET M44
M44 AND INPOS3 = M41
With CNC channel selected (M41=1)
With the PLC channel selected (M41=0)
Sercos
When using SERCOS communication with the servo drive, the axis being applied the velocity
command and feedback data is selected by the mark of the secondary axis SWITCH3 (M5205).
axis parameter SWINBACK (P66) of the secondary axis must be set to "0".
M40 AND M41 = DRO3 W axis as DRO
= SERVO2ON Z axis normal
= RES SWITCH3 Z axis velocity command
M40 AND NOT M41 = DRO2 Z axis as DRO
= SERVO3ON W axis normal
= SET SWITCH3 Z axis velocity command
Z axis (main) W axis (secondary)
DFORMAT for W =0 (not displayed).
SWITCHAX for Z = 0 SWITCHAX for W = 3 (Z axis)
SWINBACK for Z axis = 0 SWINBACK for W = 0
