Chapter 4 Parameters Example 3: The whole scale of the potentiometer may be used as desired. In addition to the signals 0 to 10V and 4 to 20mA, other popular voltage signals include 0 to 5V, 20 to 4mA or that under 10V. Max.

As an option, you also could set Pr. 03 =120Hz. Max. Output Pr.03 Freq. 60Hz Gain adjustment 30Hz 0Hz 0V Revision Aug. 2015, ME16, SW V3.13 5V 30 Factory Settings Pr.03=60Hz--Max. output Freq.
