The encoder interface 1 is the connection for the speed feedback of the KEB COMBIVERT
F4-F, which is imperative for the entire control (current control, too).

U is an unstabilized voltage that is provided by the power stage of the KEB COMBIVERT.
var
Dependent on the size of unit and the load, the voltage amounted to 15... 30 V DC (see
chapter 6.9.6). Uvar is loadable at X4 and X5 with altogether 110 mA. If higher voltages /
currents to supply the encoders are needed then the control must be supplied with an external
voltage.
The +5 V voltage is a stabilized voltage and loadable at X4 and X5 with altogether 300 mA.
The signal and reference marking inputs can be triggered with rectangular pulses as well as
sine-wave signals. The signal inputs must generally be connected. The reference marking
singals are only needed for the reference point approach in the positioning operation.
Following specifications apply to the encoder interface 1 (X4):
• max. operating frequency of input f
• internal terminating resistor R
• 2...5 V high level at rectangular signals
• U = 2,5 V and 1 Vss at sine / cosine signals
