Flux controller:
-
dS.11 KP flux
-
dS.12 KI flux
- dS.13 magnetising current limit
Inertia:
- cS.25 inertia (kg x cm

)
Speed controller (preloaded only if automatic speed controller setting is activated by
cS.26 ≠ 0):
- cS.06 KP speed
- cS.09 KI speed
only for ASCL (F5-H):
- dS.14 KP speed calculation ASCL
- dS.15 KI speed calculation ASCL
- dS.19 Limit uf-control dec ASCL
Some of these parameters (e.g., the limiting characteristic) depend upon the available voltage.
During vector controlled operation, the voltage stabilization generally should be "off". The software-integrated
current controllers control the voltages and a simultaneous intervention of the voltage stabilization increases
the system´s vibrational tendencies.
uF.09 Voltage stabilization
Value Function
1120 off
With Fr.10 = 1, precharging occurs dependent on the voltage class of the inverter (400V or 230V)
The actual DC link voltage of the frequency inverter, which is proportional to the supply input voltage is consi-
dered for the calculations at Fr.10 = 2.
If the parameter „voltage stabilisation“ (uF.09) is not set to the default value „1120: off“, then the value in uF.09
is taken as reference voltage for the calculations for settings Fr.10 = 1 or 2.
If the drive is to be operated at a different voltage then during initial start-up, proceed as follows:
In parameter uF.09, enter the nominal voltage to be used later, activate Fr.10 = 1 and reset parameter uF.09 to
"off".
Attention:
After
completion of a possible "fine tuning", i.e., the manual
adjustment of controller parameters, torque limits,
etc., parameter Fr.10 may not be activated anymore. Otherwise, the manually adjusted parameters will be
overwritten by the calculated values!
7.5.2.1.3 Speed feedback and selection of the speed direction
The actual value source for the speed must be selected in parameter cS.01.
Possible values for drives with speed encoder are 0 (speed measurement via encoder interface channel 1) or
1 (speed measurement via encoder interface channel 2).
Description of the correct parameter setting of the encoder interfaces is made in chapter 7.11 "Speed measure-
ment".
If operation without tachometer generator is desired, cS.01 = 2 (calculated actual value) must be selected.
