The specified value defines how the relevant input signal is converted into a torque, a speed or a
positioning setpoint value. Input voltages in the value range from –10 V … +10 V are processed.
• Specify in the respective registers in the FCT which value of the respective input variables corres-
ponds to an input voltage of 10 V. The scaled range corresponds to a linear characteristic curve
symmetric to the zero point (e.g. –1000 R/min … +1000 R/min).
Correction
With an externally specified voltage 0 volt, an undesired setpoint value can still be generated due to
voltage differences. For zero balancing, you can manually enter an offset in the FCT or execute syn-
chronisation automatically (recommendation).
Through zero balancing, the scaled range is divided asymmetrically (example Fig. 6.8:
–750 … +1250 R/min).
Procedure for “Automatic offset calibration”:
1. Connect the input with the potential corresponding to the setpoint value = 0.
2. Now carry out the “Automatic offset calibration” via FCT.
Analogue outputs
To configure the analogue outputs (AOUT):
• Select the respective desired output signal, e.g. setpoint or actual value of the controlled variable in
the FCT.
• Adjust the required settings and values (scaling, numerical overflow limitation) of the outputs used.
Analogue monitor
The motor controller has two analogue outputs AOUT 0 and AOUT 1 for output, e.g. of controlled vari-
ables, which can be represented with an external oscilloscope. The output voltage lies in the range of
-10 V to +10 V.
• Select the output variable that should be output through the analogue monitor.
• For output variable “Fixed clamping value”: In the “spanning value” field, set the voltage that
should remain constant at the output.
• For other output variables: In the “Scaling” field, set which value of the selected size corresponds to
an output voltage of 10 V.
