Pr
21.03
defines how the value of Pr
1.49
is derived as follows:
*The bit Pr
1.41
to Pr
1.44
can be controlled to force the value of Pr
1.49
:
all bits equal to zero gives 1,
Pr
1.41
= 1 then Pr
1.49
= 2
Pr
1.42
= 1 then Pr
1.49
= 3
Pr
1.43
= 1 then Pr
1.49
= 4
Pr
1.44
= 1 then Pr
1.49
= 5
The bit parameters with lower numbers have priority over those with higher numbers.
Pr
1.49
and Pr
1.50
then define the reference as follows:
Keypad reference
If Keypad reference is selected the drive sequencer is controlled directly by the keypad keys and the keypad reference parameter (Pr
1.17
) is
selected. The sequencing bits, Pr
6.30
to Pr
6.34
, have no effect and jog is disabled.
Reference selected by timer
The presets are selected automatically in turn. Pr
1.16
defines the time between each change.
