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.
Pr 1.15 defines how the value of Pr 1.50 is derived as follows:
*Pr 1.45 to Pr 1.47 can be controlled by digital inputs to define the value of Pr 1.50 as follows:
**The presets are selected automatically in turn. Pr 1.16 defines the time between each change.
Pr 1.49 and Pr 1.50 then define the reference as follows:
This parameter defines the time between preset reference changes when Pr 1.15 is set to 9. If Pr 1.48 is set to 1 then the preset counter and timer are
reset and preset 1 will be selected.
