Parameter | Name:
C00015 | VFC: V/f base frequency
Data type: UNSIGNED_16
Index: 24560 d = 5FF0 h
V/f base frequency for V/f characteristic control ( VFCplus ) and V/f control ( VFCplus+encoder )
• The motor voltage increases linearly with the frequency until the base frequency is reached. From this value on,
the motor voltage remains constant, the speed increases and the maximum torque decreases.
• After the motor to be used has been selected from the motor catalogue, the suitable value can be entered
automatically. An automatic detection via the motor parameter identification is possible as well.

Parameter | Name:
C00016 | VFC: Vmin boost
Data type: UNSIGNED_16
Index: 24559 d = 5FEF h
Boost of the V/f voltage characteristic in the range of small speeds or frequencies with V/f characteristic control
( VFCplus ) and V/f control ( VFCplus+encoder )
• This may increase the starting torque.
• After the motor to be used has been selected from the motor catalogue, the suitable value can be entered
automatically. An automatic detection via the motor parameter identification is possible as well.

C00018 | Switching frequency
Data type: UNSIGNED_8
Index: 24557 d = 5FED h
Selection of the pulse width modulated switching frequency transferred from the inverter to the motor
• When a variable switching frequency is selected, the switching frequency may change as a function of the load
and rotational frequency.
