8.8 Drive optimization
SINAMICS DCM DC Converter
338 Operating Instructions, 12/2018, A5E34763375A
Procedure
〈1〉
The drive must be in operating state o7.0 or o7.1 (enter SHUTDOWN!).
〈
2〉
p50051 = 23
Optimization of the ar
mature current control for induction load
p50051 = 24
Optimization of the field current control
p50051 = 25
Optimization of the armature current control
p50051 = 26
Optimization of the speed control
p50051 = 27
Optimization of the EMF control (incl. field characteristic recording)
p50051 = 28
Recording of the friction characteristic
p50051 = 29
Optimization of the speed control for drives with a mechanical system
capable of oscillation
〈
3〉
The SINAMICS DCM C
ontrol Module goes into operating state o7.4 for a few
s
econds, and then goes into o7.0 or o7.1 and waits for SWITCH ON and
OPERATION ENABLE to be entered.
Enter the commands SWITCH ON and OPERATION ENABLE!
If the switch
-on command is not entered within 30
s, this wait state is exited and fault
message F60052 is output.
〈
4〉
Execution of the optimization run starts once operating state <o1.0 (OPERATION) is
reached.
〈
5〉
When the optimization run has been completed, the drive goes into operating
state o8.0
Note
The optimization runs should be performed in the order specified previously.
Details on the individual optimization runs
p50051 = 23
Optimization of armature current control for inductive load
This optimization run sets the same parameters as for p50051
= 25. The
optimization run uses an algorithm that is more suitable when it comes to
feeding large inductances than for the algorithm used with p50051
= 25. As
a consequence, for applications wher
e the SINAMICS DCM does not feed a
motor
– but instead a lifting solenoid or the field of the synchronous
gener
ator – it is recommended that instead of p50051 = 25 this optimization
run is executed.
p50051 = 24
Optimization of closed-loop field-current control
(duration of up to 1 min.)
This optimization run may also be executed without a mechanical load
co
nnected.
The following parameters are set automatically:
p50112, field re
sistance (Rf)
p50116, field inductance (Lf)
p50255, P gain of field
-current controller (Kp)
p50256, integral time of field
-current controller (Tn)
