66 Configuring Axis Use
Transducer Resolution
Conversion Constant (K)
To allow axis position to be displayed and motion to be programmed in
the position units specified in the Units Tab, a conversion constant must
be entered for each axis. The conversion constant (K) lets you convert
your position units into encoder (feedback) counts and vice versa. For
physical and virtual axes, enter a value for K which is the number of
encoder (feedback) counts per position unit using up to 10 digits.
The S-Class motion controllers use 4X encoder decoding (both edges of
Channel A and B are counted). The count direction is determined from
both the direction of the edge and the state of the opposite channel.
Channel A leads Channel B for increasing count. This is the most
commonly used decode mode with incremental encoders, since it
provides the highest resolution.
