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).
With control word transition from 0xnnF to 0x000F, “Velocity mode” will be stopped.
Then, the mode can be restarted via 0xnnF.
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.
