Value Function Description
11 Torque precontrol A function which enables a value for the anticipated torque requirement to be entered
in the controller (interference factor switching). This function can be used to improve
the load take-up of lifting equipment with separate load detection.

13 Multiplication The setpoint is multiplied by the stated analog value. The analog value adjusted to
100% then corresponds to a multiplication factor of 1.
14 Actual value process
controller * Activates the process controller, analog input 1 is connected to the actual value sensor
(compensator, air can, flow volume meter, etc.). The mode (0-10 V or 0/4-20 mA) is set
in P401.
15 Process controller
setpoint * as function 14, however the setpoint is specified (e.g. by a potentiometer). The actual
value must be specified using another input.
16 Process controller
precontrol *: adds an adjustable additional setpoint after the process controller.
46 Setpoint Torque Process
controller Process controller torque setpoint
48 Motor temperature Motor temperature measurement with KTY-84, details in Section 0
53 d-correction F process "Diameter correction for PID process controller frequency"
54 d-correction Torque "Diameter correction of torque"
55 d-correction F + Torque "Diameter correction for PID process controller frequency and torque"
*) further details regarding the process controller can be found in Section 0and P400
**) The limits of these values are set by the parameters >Minimum frequency auxiliary setpoints< P410 and >Maximum frequency auxiliary
setpoints< P411.
Further analog functions (47/49/56/57/58) are only relevant for POSICON.
NOTE: An overview of the scaling of the various setpoints can be found in Section 0.

List of possible functions of the analog inputs
The analog inputs of the frequency inverter can also be parameterised to process digital signals.
The digital functions are set in the parameter of the relevant analog input according to the following
assignment.
