Synchronous operation; Program 2:
Slave speed factor: 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:

Synchronous operation; Program 2:
Synchronizing error display factor: 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 synchronization: The factor should be 100, the synchronizing error is then
displayed in RPM related to the slave.

Virtual master reference value: Select here the type of reference value for the virtual
master.
0 = reference value signal 0.. ±10V via Terminal 53,
1 = reference value signal 0.. ±20mA via Terminal 60,
2 = reference value can be set via Parameter 216.
3 = reference value is set via Field bus (PCD 2). +/- 1000 corresponds to maximum
virtual master velocity (parameter 750).
