*The bit Pr 1.41 to Pr 1.44 and Pr 1.52 can be controlled to force the value of Pr 1.49 , as follows:
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
Pr 1.52 = 1 then Pr 1.49 = 6
The bit parameters with lower numbers have priority over those with higher numbers.
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.
