- 111 -
1820 Command multiplier for each axis (CMR)
NOTE
When this parameter has been set, the power must
be turned off before operation is continued.
[Data type] Byte axis
Set a command multiplier indicating the ratio of the least
command increment to the detection unit for each axis.
Least command increment = detection unit × command multiplier
