Fixed setpoint
See also function diagram 3115 in the SINAMICS DCM Parameter Manual.
The "Fixed setpoint" function can be applied via the binectors selected using p50430 index
.00 to .07, and via p50680 and p50681 (see function diagram for logic operation).
"Fixed setpoint" is applied by one of more of the sources referred to (binectors) entering the
log. "1" state. During this, each source is assigned a setpoint (to be selected using p50431).
If "Fixed setpoint" is applied by several sources at the same time, their corresponding
setpoints are added together (limited to ±200%).
For each source with which "Fixed setpoint" can be applied, p50432 may be used to
determine whether the ramp-function generator is bypassed. In this case, the ramp-function
generator operates with ramp-up time = 0 and ramp-down time = 0.
Response when "Fixed setpoint" is applied:
The fixed setpoint is switched in instead of the r52211 setpoint.
Withdrawal of "Fixed setpoint":
If all possible sources for switching in the fixed setpoint are in the log. "0" state again, r52211
is switched through as a setpoint.
