19-13 Slave speed factor
Option:
Function:
Enter here the factor by which the slave speed must be scaled,
so that the desired value is displayed. The following formula
applies for calculation of the factor:

19-15 synchronising error display factor
Option:
Function:
Enter the factor by which the error must be scaled, so that the
desired value is displayed. The formula for calculation of the
factor is:
Speed synchronisation: The factor should be 100, the synchro-
nising error is then displayed in RPM related to the slave.

19-16 Virtual master reference value
Option:
Function:
Select the type of reference value for the virtual master.
[0]
reference value signal 0.. *10V via Terminal 53,
[1]
reference value can be set via par. 310 subindex 1.
[2]
reference value is set via Field bus (PCD 2). +/- 1000 corre-
sponds to maximum virtual master velocity (par. 1918).
