Pr 1.49 and Pr 1.50 then define the reference as follows:
x = any value
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:
Pr 1.49 Pr 1.50 Reference
1 1 Analog reference 1 (Pr 1.36)
1 >1 Preset defined by Pr 1.50 (Pr 1.21 to Pr 1.28)
2 1 Analog reference 2 (Pr 1.37)
2 >1 Preset defined by Pr 1.50 (Pr 1.21 to Pr 1.28)
3 x Preset defined by Pr 1.50 (Pr 1.21 to Pr 1.28)
4 x Keypad reference (Pr 1.17)
5 x Precision reference (Pr 1.18 and Pr 1.19)
6 x Keypad reference only
