For
the addition of the reference frequency + the reference line value.
Note:
The reference values can be controlled at the frequency inverter via the control unit
KP500 or the control software VPlus via the following parameters:
-

-
Note:
For information on the reference frequency channel, refer to the frequency inverter
operating instructions.

Ramp Setpoint
434 = 3, the sign of the overall reference value is obtained from
Ramp Setpoint
If
value is limited to fmin.
In this case, consider that the sign in front of fmin with reference value =
0 is derived from the sign in front of the last reference line value which
was not 0.
After Mains On, the reference line value is limited to +fmin (motor clock-
wise).
Internal Reference Frequency
Reference Bus Frequency
Reference Ramp Frequency
If the serial interface of the communication module CM-232 / CM-485 is
connected to a PLC, for example, VPlus cannot access the frequency in-
verter via this interface directly.
In this case, the PC must be connected via the optional interface adapter
KP232.
