20.07 TorqMaxSPC (maximum torque speed controller)
Maximum torque limit - in percent of MotNomTorque (4.23) - at the output of the speed controller:
−
TorqRef2 (2.09)
Note:
The used torque limit depends also on the converter's actual limitation situation (e.g. other torque limits,
current limits, field weakening). The limit with the smallest value is valid.

23.01 SpeedRef (speed reference)
Main speed reference input for the speed control of the drive. Can be connected to SpeedRefUsed (2.17)
via:
−
Ref1Mux (11.02) and Ref1Sel (11.03) or
−
Ref2Mux (11.12) and Ref2Sel (11.06)

Sample of parameters
Parameter changes by DCS Control Panel or DWL are stored in the flash. Changes made by the overriding
control are only stored in the RAM.
Min., max., def.:
Minimum and maximum value or selection of parameter.
Default value or default selection of parameter.
Unit:
Shows the physical unit of a parameter, if applicable. The unit is displayed in the DCS Control Panel and
DWL.
Group.Index:
Signal and parameter numbers consists of group number and its index.
Integer Scaling:
Communication between the drive and the overriding control uses 16-bit integer values. The overriding control
has to use the information given in integer scaling to change the value of the parameter properly.
Example1:
If the overriding control writes on TorqMaxSPC (20.07) 100 corresponds to 1 %.
Example2:
If the overriding control writes on SpeedRef (23.01) 20,000 equals the speed (in rpm) shown in
SpeedScaleAct (2.29).
Type:
A short code shows the data type:
I = 16-bit integer value (0, …, 65536)
SI = 16-bit signed integer value (-32768, …, 32767)
C = text string (ENUM)
Volatile:
Y = values are NOT stored in the flash, they will be lost when the drive is de-energized
N = values are stored in the flash, they will remain when the drive is de-energized
