3.3 Fixed setpoints
This function can be used to specify preset speed setpoints. These fixed setpoints are
defined using parameters and selected via binector inputs. Both the individual fixed setpoints
and the effective fixed setpoint are available for further interconnection via a connector
output (e.g. to connector input p1070 - CI: Main setpoint).
Properties
● Number of fixed setpoints: Fixed setpoint 1 to 15
● Selection of fixed setpoints: Binector input bits 0 to 3
–
Binector input bits 0, 1, 2 and 3 = 0 → setpoint = 0 active
– Unused binector inputs have the same effect as a "0" signal
Parameterization with STARTER
In the STARTER commissioning tool, the "Fixed setpoints" parameterizing screen form in the
project navigator under the relevant drive is called by double-clicking "Setpoint channel" >
"Fixed setpoints".
