• The PLC SGEs for selecting gear ratios are described in
Chapter 4.3, "Interface signals".
• The motor encoder system is parameterized the same in the drive machine
data and in the NCK machine data.
• The example should be applicable for the 1st drive.
• Enabled SI function SBH/SG.

• Definition of SGEs/SGAs in the NCK monitoring channel
– for 840D
Logical slot for the terminal block: 5
Slot number of the sub-module for SGEs: 3
I/O number for the signal "gear ratio selection bit 0": 1
I/O number for the signal "gear ratio selection bit 1": 2
Note
The SGEs/SGAs used in the NCK monitoring channel must also be supplied
by the machine manufacturer in the drive monitoring channel.
Parameter set changes via SGEs must be coupled to a parameter set change
in the NC.
