Minimum Setting Unit
174
The CS1W-MC421 setting window for CX-Motion is shown below.
The MC Unit can manipulate position data ranging from –39,999,999 to
+39,999,999 when the minimum setting unit is set to 1 (the default setting).
The minimum setting unit can be set to 0.1, 0.01, 0.001, or 0.0001 to provide
greater precision but a more limited range, as shown in the following table.
Min. setting unit
1 –39,999,999 to +39,999,999
0.1 –3,999,999.9 to +3,999,999.9
0.01 –399,999.99 to +399,999.99
0.001 –39,999.999 to +39,999.999
0.0001 –3,999.9999 to +3,999.9999
Depending on the pulse rate, the range of command values might be smaller
than the range shown in the table above. Set the maximum command values
based on the following two conditions.
• |Max. command value (C)|
• |Max. command value (C)| £ 39999999(C)
P: Pulse rate ([pulses/pulse], [mm/pulse], [degrees/pulse], [inches/pulse])
C: Minimum setting unit (0.1, 0.01, 0.001, or 0.0001)
For example, when the minimum setting unit is 0.01 and the pulse rate is
0.0001:
1073741823 0.0001 = 107,374.1823 < 399,999.99
Since the minimum setting unit is 0.01, the command value range is
–107,374.18 to +107,374.18.
