11.4.5.1 Example sequence
In order to start “Table travel record mode”, the correct sequence must be sent by the
PLC.
(Table travel record mode)
Start motion block 1 as single motion block
Operation enabled and Positioning active.
Operation enabled and Target reached.
Start motion block 2 as single motion block
Operation enabled and Positioning active.
Operation enabled and Target reached.
Start motion block 3 as single motion block
Operation enabled and Positioning active.
Operation enabled and Target reached.
Start motion block 1 as sequence motion
block
Operation enabled and Positioning active.
Operation enabled and Target reached.
Resume previous motion block as single mo-
tion block
Operation enabled and positioning active.
Operation enabled and target reached.
Resume previous motion block as sequence
motion block
Operation enabled and positioning active.
Operation enabled and target reached.
Dangerous state due to new mode!
If
Override Modes Of Operation 1454 is changed during operation (control word =
0xnnnF), a dangerous state may occur in the new mode.
• Before changing
Override Modes Of Operation 1454
,
check the status word
(e.g. for status 0xnn33).
Once the sequence of the first four status words has been processed correctly, the
ACU is ready for operation (dark table area).
In state “operation enabled” (0xnnnF), the state of the Motion Control can be changed
(white table area).
Bit 9 “Start motion block” must be active during positioning. If bit 9 is reset to “0”, the
positioning operation is interrupted.
As long as 0x0007 is active, the “Modes of Operation” can also be changed safely.
Once
Override Modes Of Operation 1454
has been set to another value, operation
can be started with a corresponding sequence.
