6.2 Operating mode
6.2.1 Preliminary information
EVDRIVE03 implements a stepper motor control according to the state machine presented in the table here below
(hereinafter the document will make reference to these status).
The state in which the algorithm is in may be readable in the FSM status (Finite State Machine, parameter Stat).
FSM Meaning
0 initialization
1 synchronization wait
2 positioning wait
3 probe alarm
4 grid alarm
5 communication alarm
10 stand-by off
11 stand-by on
30 analog positioner
40 stabilization
41 start-up
42 algorithm selection
50 manual
51 debugger
60 reserved
61 SH algorithm
6.3 Stand-by and operation mode selection
At the end of the resynchronization operations the machine will enter the stand-by state, during which the installer
parameters are loaded and configurations are checked.
In this status can be modified the installer parameters, that take effect immediatly, and also the manufacturer
parameters, that require a reset.
If there are no configuration errors, represented in the Alarm status (parameter AlSt) and Configuration warning
(parameter CoWa), the valve can be enabled.
