1.3.2 Unit of Increment Systems
In different increment system, the least input/output increment varies with metric/inch system. The
specific data is shown as follows:

Least input increment (for input) is metric or inch can be set by G20 or G21.
Least command increment (for output) is metric or inch is determined by machine tool and set by bit
SCW of parameter NO.004.
1.3.3 Data Ranges of Increment System
Limited by pulse output frequency, the data ranges may vary due to different increment system.
