0 1 = fixed setpoint bit 0 Selects up to 16 different fixed
setpoints.
p1020[0] = r2093.0
1 1 = fixed setpoint bit 1 p1021[0] = r2093.1
2 1 = fixed setpoint bit 2 p1022[0] = r2093.2
3 1 = fixed setpoint bit 3 p1023[0] = r2093.3
4 1 = DDS selection bit 0 Changes over between settings
for different motors (drive data
sets).
p0820 = r2093.4
5 1 = DDS selection bit 1 p0821 = r2093.5

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