Changes over the control mode
for vector control.
p1501[0] = r2093.12
13 1 = no external fault
0 = external fault is active (F07860)

Not used
15 1 = CDS bit 1 Changes over between settings
for different operation interfaces
(command data sets).
p0811[0] = r2093.15

If you switch from telegram 350 to a different one, then the inverter sets all interconnections
p1020, … to "0". Exception: p2106 = 1.
