The given tolerances (see parameter description) refer to the respective maximum values with the dimensioning KEB COMBIVERT: Motor = 1:1. Dependent on the data from the motor manufacturer, larger tolerances at the torque displays are possible, due to the usual variations in the machine parameters and temperature drifts.

Parameter The frequency inverters KEB COMBIVERT F5-GENERAL and F5-BASIC contains 16 Parameter (>= D=housing 17) fixed, one free-to-define parameter group. We have already learned about the free-to-define group (CP). In the fixed parameter groups the parameters are 5.1 Parameter combined function-related.

021Ah The KEB COMBIVERT can fall back on 8 internal parameter sets (0-7). Through corresponding programming the inverter can independently change parameter sets and is thus able to drive different operating modes. This parameter shows the parameter set, with which the inverter is currently running. Independent of it another parameter set can be edited by bus (also see chapter 6.8).

-100 0,01 The motorpoti-function in the KEB COMBIVERT imitates a mechanical, motor operated potentiometer. The control occurs via 2 programmable inputs (Ñpoti upì and Ñpoti downì). The display is limited by oP.53/54. The adjustment of the motorpoti is done with the parameters oP.50...oP.59 (also see Chapt. 6.9.3 ÑMotorpotiì). By way of the bus the motorpoti can be set to any chosen value between -100...100%.

6.4 Setpoint-, Rotation- and Ramp Adjustment 6.4.1 Brief Description The setpoint values of the KEB COMBIVERT F5 can be preadjusted analog as well as digital. The AUX-function adds or multiplies an analog setpoint to/with other setpoint settings. The setpoint and rotation selection links the different setpoint sources with the possible sources of rotation direction.
Setpoint- and Ramp Adjustment 6.4.4 Fixed values The KEB COMBIVERT supports up to 3 fixed values for each parameter set, which can be selected via two digital inputs. With oP.19 and oP.20 the inputs required (oP.18...23) for the selection are defined (also see ÑDigital inputsì Chapt. 6.3.10). The rotation direction source for fixed value mode is defined with oP.18.

11.1.8 Sercos Operator The herein described unit is a plugable operator with SERCOS-interface for the frequency inverter or servo KEB COMBIVERT F5. As far as possible the hard and software were 00.F5.060-6000 developed taking the DIN/EN 61491 into consideration. The voltage supply is made by the inverter and as an independend external supply it can be made via the terminal strip of the inverter.

The value „off“ deactivates the function. 11.2.6 Automatic storing With the factory setting the KEB COMBIVERT immediateley stores all parameter changes non-volatile. However, most bus applications where new values are preset in (ud.5) a cyclic manner do not require this function.
