It is not possible to switch up from phase 2 to phase 3

IDN 21 contains all parameters that prevent phase runup. These are predominantly
timings, which come from the control system and are checked in the drive. However, the
configuration of the AT and MDT is also checked here with regard to the operating mode.
Speed control stipulates that the MDT also contains the target speed value.
The following parameters MUST be written by the control system:
IDN 1
IDN 2
IDN 6
IDN 9
IDN 10
IDN 15
IDN 16
IDN 24
IDN 32
IDN 89

Every time the phases are switched back, i.e. also every time the control system is
intentionally switched off!
If two consecutive (back-to-back) MSTs or MDTs fail
If the software enable is issued before the hardware enable without it having been
configured with IDNP 3016
®
If the sercos ASIC has an unexpected version number (unlikely).
If the hardware enable switches to 0V with servo amplifiers released via sercos
In the event of cable break.
Control system wants to switch to a phase greater than 4.
The next phase requested by the control system would skip one or more phases.
Switching is to be performed to phase 3 without the command IDN127 having first
been successfully executed.
Switching is to be performed to phase 4 without the command IDN128 having first
been successfully executed.
Do all servo amplifiers have the same baud rate (SBAUD)?
Do all servo amplifiers have a unique address (ADDR)?
The light output (SLEN) might not be set optimally. The light output can effectively
only be set in the following steps:
0 1-14 15- 30
With 16 Mbaud, 30 is the maximum light output and the only steps available are 0-10
and 11-30.

Are all required values on the operating mode

match the length?
