7 Drive Machine Data (SIMODRIVE Drive MD) 07.97
7.3.2 Drive MD (data description)
P gain flux controller 1150
Default value Lower input limit Upper input limit Units
400.0 0.0 100 000.0 A/Vs
Active
at once
Input of the proportional gain of the flux controller or automatic paramterization (initialization)
through the operator action Calculate controller data.
Note:
This data is relevant only for MSD drives.
Integral-action time flux controller 1151
Default value Lower input limit Upper input limit Units
10.0 0.0 500.0 ms
Active
at once
Input of the control variable integral-action time flux controller or automatic paramterization by
the operator action Calculate controller data.
Speed for start of flux detection 1160
Default value Lower input limit Upper input limit Units
1 500.0 200.0 50 000.0 rev/min
Active
at once
Above the set speed flux detection is active, below the set speed a flux model is used. The
parameter default is set for "Calculate controller data" and should not be changed.
Note:
This machine data only applies to main spindle drives.
DC link fixed voltage 1161
Default value Lower input limit Upper input limit Units
600
0 (as from SW 6)
0 700 V
Active
at once
By specifying a DC link fixed voltage > 0V DSP internal DC link measurement is deactived
here, i.e. MD 1701 (between loop voltage display) is inactive (display: "
* ").
The given voltage is included instead of the measurement in:
• DC link adaptation
• Flux acquisition (MSD)
The permissibility of an activation of the DC link measurement (MD 1161=0) is monitored in
accordance with hardware configuration 5 (error message 300765).
Caution:
It is not possible to activate emergency retractive functions with deactivated DC link
measurement (MD 1161 > 0) (error message 300764).
