Example Sequence
To start the Table travel record mode, the correct sequence has to be sent from the
PLC.
1 Control word =
0x0000
Disable voltage
1 Status word =
0x0050 Switch On Disabled
2 Modes of Operation = -1
(Table travel record mode)
3 Control word =
0x0006
Shutdown
Status word =
0x0031 Ready to switch on
4 Control word =
0x0007
Switch On
Status word =
0x0033 Switched On
5a Control word =
0x000F
Enable Operation.
Status word =
0xnn37 Operation enabled
5b Control word =
0x020F
Start Motion Block 1 as Single Motion Block.
Status word =
0xn337 Operation enabled and Positioning active.
Status word =
0xn637 Operation enabled and Target reached.
5c Control word =
0x0A0F
Start Motion Block 2 as Single Motion Block.
Status word =
0xn337 Operation enabled and Positioning active.
Status word =
0xn637 Operation enabled and Target reached.
5d Control word =
0x120F
Start Motion Block 3 as Single Motion Block.
Status word =
0xn337 Operation enabled and Positioning active.
Status word =
0xn637 Operation enabled and Target reached.
5e Control word =
0x021F
Start Motion Block 1 in Sequence Mode
Status word =
0xn337 Operation enabled and Positioning active.
Status word =
0xn637 Operation enabled and Target reached.
5f Control word =
0x004F
Resume last Motion Block as Single Motion
Block
Status word =
0xn337 Operation enabled and Positioning active.
Status word =
0xn637 Operation enabled and Target reached.
5g Control word =
0x005F
Resume last Motion Block in Sequence Mode
Status word =
0xn337 Operation enabled and Positioning active.
Status word =
0xn637 Operation enabled and Target reached.
WARNING
Dangerous state due to new mode!
•
When
is changed during operation (Control word =
0xnnnF), a dangerous state can occur in the new mode.
•
Checking the status word before changing
(i.e. check
state 0xnn33).
After the sequence of the first four Control word s was processed correctly, the ACU is
enabled (dark marked table area).
In “Operation enabled” state (0xnnnF) the Motion Control states can be changed
(white marked area in table).
With the control word transition from 0xnnnF to 0x0007 the velocity mode is stopped.
After that it is possible to start again with 0xnnnF.
While 0x0007 is active, it is also possible to change the modes of operation without
to another value you can start
the new operation mode with the according sequence.
