Step referencing
It is possible to predefine four step references. The step references are selected with
digital inputs. Step reference activation overrides the external speed reference.
This function operates on a 6 ms time level.
The four step references are based on a combination of three digital inputs, for
example, DI3, DI4 and DI5.
If you need any other combination than three digital inputs, you can use the following
parameters for defining the combination. For example, if you need two-step
references with one digital input, you can set:
• Parameter
STEP REF SEL to STEP POINTER (Speed defined by pointer
selections)
• Parameter
to, for example, 500 rpm
• Parameter
to, for example, 1000 rpm
• Parameter
to, for example, +.001.017.04 (= DI5)
After this:
• If DI5 = 0, step reference 500 rpm is valid by par. 12.02.
• If DI5 = 1, step reference 1000 rpm is valid by par. 12.03.
