Operating Instructions ACU
12/16
15 Reference Values
The ACU series frequency inverters can be configured specific to the application and enable
customer-specific adaptation of the module hardware and software structure.
15.1 Frequency Limits
The output frequency of the frequency inverter and thus the speed setting range are defined by the
parameters Minimum Frequency 418 and Maximum Frequency 419. The relevant control methods
use the two limit values for scaling and limiting the frequency.

15.2 Slip Frequency
The torque-forming current component and thus the slip frequency of the
3-phase machine depend on the required torque in the case of the field-oriented control methods.
The field-oriented control method also includes the parameter Slip Frequency 719 to limit the
torque in the calculation of the machine model. The rated slip calculated from the rated motor
parameters is limited in accordance with the Slip Frequency 719 which is parameterized as a
percentage.

15.4 Frequency reference channel
The different functions for the defining the reference frequency are connected via the frequency
reference value channel. The Reference Frequency Source 475 determines the additive assignment of
the available reference value sources depending on the hardware installed.
