7.5.4 Control methods
Table 7. Three different control methods:
1
EP
Electronic potentiometer function.
Stepless control using a 2-step controller.
2
MS
Multistep control (2 steps)
Requires programmable digital inputs for speed reference steps
3
AU
Automation control for any control device with an output in the range of 0 –
10V
E.g. radio controls, process computers.
All control methods are available without any changes in the hardware or software.
The control mode is selected by parameter P1.1.11 Input set. The parameter assigns digital inputs S1, S2
and DID3-DID5. It is not possible to change the functions of the inputs separately. The state of inputs can be
checked from parameter V2.3.
