3.3 Analog output
3.3.1 Short description analog output
The KEB COMBIVERT has one programmable analog output (ANOUT1). The variable which shall be output
at the outputs X2A.21 can be selected with An.31. ANOUT 3 and ANOUT 4 (An.41 / 47) can be output as
switching condition 42 or 43 with the digital outputs as PWM signal. The analog signal can be adapted to the
requirements with the characteristic amplifiers ( An.33...35 / 43...45 / 49...51). The ru parameters display the
actual size before and after amplification. The period for the PWM signal can be adjusted with An.46/ 52.

3.3.2 Output signals
ANOUT 1
A voltage of 0...±11,5 VDC displays the selected size in the range of 0...±115 % with a resolution of 10 bit at
the output. In order to compensate load-dependent voltage drops, the limitation at the output of the characte-
ristic amplifier is ±115 %.
