The KEB COMBIVERT F4-F incorporates one differential voltage input for setpoint
setting (REF1 ±), one programmable differential voltage input (REF2 ±) and two
programmable analog outputs (A1 / A2). Depending on the analog input or output
signal function, offsett and gain can be adjusted.
The analog inputs of an digital filter are smoothed by means of averaging. The digital
signals are now available for the characteric amplifiers. In the characteristic amplifier
the input signals can be influenced in X- and Y-direction as well as in the gain. To
avoid voltage fluctuation and ripple voltages around the zero point the analog signal
can be suppressed up to 10 % around the zero point.
