Parameter setting
The parameters to be set are strongly dependent on the motor used, the inertia of the driven machine
and the drive configuration (single drive, drive network, master−slave operation, etc.). This function
must therefore be adapted to the individual application in every case.
The following specifications refer to the description of the mains failure detection. (

Important settings prior to the initial commissioning:
1. Save the settings in a parameter set (e.g. parameter set 4).
Stop!
With internal voltage supply to the terminals (C0005 = xx1x), terminal X6/63 is used as a voltage
source for external potentiometers. In this case, measure across terminals +U
G
, −U
G
.
2. Measure the DC−bus voltage with an oscilloscope (channel 1):
– With a suitable voltage divider across the terminals +UG, −UG or
– by providing the DC−bus voltage at terminal X6/62, for instance. To do this, set
C0436 = 5005 (MCTRL−DCVOLT). 1 V at terminal X6/62 corresponds to 100 V at +UG, −UG.
3. Measure the speed with an oscilloscope (channel 2):
– By providing the speed at terminal X6/62, for instance, (standard setting). To do this, set
C0431 = 5001 (MCTRL−NACT). 10 V at terminal X6/62 correspond to n
max
(C0011).
