2.2.1 Status commands
The status can be changed by writing the status parameter, by a digital input, by the
status transition of the drive or by the keypad of the drive.
It is also possible to know the status by reading the status parameter or by looking at
the LEDs H1, H2, H3 and H4 of the DGF.
The following table shows how the LEDs change their state depending on DGF status.
LED H1 is always blinking when the DGF communicates with the drive.

If the execution of an illegal transition is attempted, the command is ignored.
Possible status transitions
1 - RESET->IDLE:
At the start up or at the reset of the card, the system moves into the IDLE condition,
and if an application program is loaded, the DGF moves automatically to READY.
Otherwise it remains in IDLE.
2 - IDLE->READY:
This transition occurs if a the program is formally correct. The following cases are
possible:
- automatic at the start up if an application program is loaded
- by writing the status parameter
3 - READY->IDLE:
This transition is possible only by writing the status parameter.
4 - 5 READY->RUN and RUN->READY:
These two transitions depend on a parameter.
By writing this parameter, it is possible to select the event that determines the transition.
Possible events are:
- only by writing the status parameter
- only by enable/disable transition of the drive
- only by digital input
