Programmable analog inputs

The drive has two programmable analog voltage/current inputs. The inputs can be
inverted, filtered and the maximum and minimum values can be adjusted. The update
cycle for the analog input is 8 ms (12 ms cycle once per second). The cycle time is
shorter when information is transferred to the application program (8 ms -> 2 ms).
