 Example
The drive runs a conveyor line. It is speed controlled but the line tension also needs
to be taken into account: If the measured tension exceeds the tension setpoint, the
speed will be slightly decreased, and vice versa.
To accomplish the desired speed correction, the user
• activates the trimming function and connects the tension setpoint and the
measured tension to it.
• tunes the trimming to a suitable level.
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).
