7.1.1.1 Main set-value
The speed is determing via via the set-value
set
(C046)and related to the adjustable
value n
max
(C011). The set-value can be selected as analog value using the input
X1/8, as dig. frequency using X5 or X9, as well as via keypad or LECOM interface.
Which input is activated depends on the operating mode set under C001 and the
signal priority set under C145/C147. The set-value channel is determined via the
configuration. A change to other signal sources is possible via the codes C145 /
C146.
7.1.1.2 Additional set-value
Also with keypad or interface operation, the additional analog set-value can be set
via the input X1/6 (or another signal source). The additional set-value (C049 /
set-value 2)is internally sent to a ramp function generator before it is combined with
the main set-value in a ”fixed” arithmetic block.The additional set-value can be
switched off via X2/E3 (C280).
With this function it is possible, forinstance, to deactivateacorrectionsignalduring
set-up (dancer position, etc.).

7.1.1.3 JOG set-values
If you need certain fixed settings as main set-values, it is possible to retrieve
set-values, which can be parameterised, from the memory using the JOG inputs.
JOG set-values replace the main set-value. Enter JOG set-values as relative values
in % of n
max
.
Parameter setting for JOG set-values
JOG set-values are set in two steps:
( Select a JOG set-value under C038.
( Enter the value selected for the JOG set-value under C039.
Repeat these two steps if you need several JOG set-values. Up to max. 15 JOG
set-values can be programmed.
