Chapter 1 Detailed Drive Operation

Point to Point Reference Setup:

• Link parameter 758 [Pt-Pt Posit Ref ] to parameter 1046 [SelSwtch

DIntOut]. The point to point reference comes from the output of the
selector switch.

• Program parameters 1029 [SelSwtch In00] through parameter 1032

[SelSwtch In03] for the 4 positions desired.

Bit Swap 1 Setup:

• Set parameter 860 [BitSwap 1A Data] = 0. Parameter 860 [BitSwap 1A

Data] sets up any data you would like to pass through to the result.

• Set parameter 861 [BitSwap 1A Bit] = 0. Parameter 861 [BitSwap 1A Bit]

sets the bit that you would like to turn on in the result and is set to bit 0 in
order to use bit swap 1 to turn on bit 0 of parameter 1022 [Sel Switch
Ctrl].

• Link parameter 862 [Bit Swap 1B Data] to parameter 824 [Local I/O

Status]. Parameter 862 [Bit Swap 1B Data] sets the data to compare.

• Set Parameter 863 [BitSwap 1B Bit] = 3. [BitSwap 1B Bit] sets which bit

of parameter 824 [Local I/O Status] is used. Bit 3 of parameter 824
indicates that digital input 3 has turned on.

• The overall function of BitSwap 1 is that when digital input 3 turns on, bit

0 is turned on as the result, which is eventually passed through to control
bit 0 “SSW DataPass” of parameter 1022 [Sel Switch Ctrl].
