Setting of the V/f characteristic:
• Limiting factors for the V/f characteristic are rated mains voltage 0x2540:001
(P208.01), minimum frequency 0x2915 (P210.00) and maximum frequency 0x2916
(P211.00).
• The base voltage 0x2B01:001 (P303.01) is usually set to the rated motor voltage
(motor nameplate data). The base voltage is preset to the rated mains voltage. This
again is preset according to the product key of the inverter. Mains voltage 117
• The base frequency 0x2B01:002 (P303.02) is usually set to the rated motor frequency
(motor nameplate data).
The current output frequency can exceed the set maximum frequency if the gain for
the slip compensation in 0x2B09:001 (P315.01) is set to a value higher than 0.

A optimisation of the control loops is not mandatory for this motor control type but
may lead to a better control mode.
