Forming the DC link (if necessary, see Section 4.3.9.6)
-
The rectifier/regenerating unit must be in status o009
less (give SWITCH ON command)
-
Set
P408 (forming time: 1.0 to 600.0 minute)
-
Select function (
P052 = 20
)
-
Press P key on the PMU
-
Press the I key on the PMU
-
The DC link is formed.
-
When forming is completed, the operating status
display appears.
(see r006)
Circuit identification
(see Section 4.3.9.7)
-
The rectifier/regenerating unit must be in operating state
o009 or less (give SWITCH OFF command!).
-
Select circuit identification (
P052 = 21
).
-
Press the P key on the PMU
-
Switch on: Press the I key on the PMU
-
Circuit identification takes place (takes about 10 s)
-
Following circuit identification, the operating display is
activated.
-
If an error occurs during circuit identification, the
identification process must be repeated (error value r949
assigned to error memory r947 can provide more
information on the cause of error (if the error in index i009
has been reset) see Sections 5.16 and 7.1)
Documenting the settings
-
Select the "Display modified parameters“ function (
P052
= 22
).
(see Section 4.3.9.8 "Display modified parameters“)
Note: Function can only be used with operator control via
the PMU
-
Enter the values of the modified (i.e. system-specific)
parameters in the logbook (Chapter 12)
-
Select the "Return" function (
P052 = 0
).
DC link voltage smoothing
-
By parameterizing P287=3 (time constant for smoothing
the DC link voltage) on the connected SIMOVERT Master
Drive FC the dynamic behavior of the closed-loop control
of the DC link voltage can be improved.
