Summary Product Description 2.1.3 Application as directed The KEB COMBIVERT is a frequency inverter with DC-voltage link. It works according to the principle of the pulse-width modulation and serves exclusively for the stepless speed control of three-phase AC motors. The unit has been developed subject to the relevant safety standards and is manufactured with the highest demands on quality.

-100 0,01 The motor-poti function in the KEB COMBIVERT simulates a mechanic, motor-driven potentiometer. The triggering is done over 2 programmable inputs („Poti up“ and „Poti down“). The display (-100…100%) relates to the fixed limits (oP.4…oP.7). In addition to the inputs the motor-poti can also be triggered with the keys „UP“ and „DOWN“. By bus the motor-poti can be set to any chosen value between -100…100%.

Different values can be selected with parameter An.14 which is then given on output X1.15. ru.41 Analog Output displays the selected value.
ANTRIEBSTECHNIK 6.3 Digital In- and Outputs 6.3.1 Short Description Der KEB COMBIVERT has 8 external digital inputs. Four of them are programmable (I1...I4). Additionally the KEB COMBIVERT has four internal digital inputs (IA...ID) Digital Inputs They are directly connected with the internal outputs.
6.4 Set Value and Ramp Adjustment 6.4.1 Short Description The set values of the KEB COMBIVERT F4-C can be adjusted analog (±REF / REF) as well as digital. The AUX-function offers the possibility to combine an analog set value with other set value adjustments.
To adjust a setpoint value two analog set values (±REF und REF), two digital set values (oP.1, oP.2), the motor-poti function, the profile parameters (Pr.8, Pr.38), the PI-Control and two channels for the speed detection are available at KEB COMBIVERT F4-C.

Parameter Sets Functional Description ANTRIEBSTECHNIK The KEB COMBIVERT has 8 parameter sets (0…7), i.e. all programmable parameters 6.8 Parameter Sets exist 8-times in the inverter and can be assigned with different values independent of each other. Thus it is possible for example to operate 8 different motors on one inverter, that means that the motor dates of each motor are in a separate set.
ANTRIEBSTECHNIK ANTRIEBSTECHNIK 6.9.7 Unit Conversion The KEB COMBIVERT makes available a parameter which allows the user to represent individual units (e.g. bottles/min or litre/hour). The source is selected with parameter ud.87. The parameters ud.88...ud.91 are for the dimensioning of the conversion. The output is done in parameter ru.43.

[kHz] Enc_ max 60000 KEB can supply a suitable encoder for the incremental encoder interface. This encoder Encoder and Cable is also used on KEB standard motors. Furthermore, prefabricated encoder cables for the connection to channel 1 (15-poles D-Sub) as well as to channel 2 (9-poles D-Sub) are available.
Functional Description ANTRIEBSTECHNIK 6.11 PI-Controller The KEB COMBIVERT is equipped with a universally programmable PI-Controller, with it pressure, temperature or dancing position controls can be set up. Through an optimal speed detection (see Chap. 6.10) a speed control with incremental encoder, tacho generator or pulse encoder is realizable.
