Feed Rate Parameters
The CS1W-MC421 setting window for CX-Motion is shown below.
Note
Feed Rate Setting Ranges
The following equation provides possible ranges for high-speed feed rates as
well as high- and low-speed feed rates for origin searches.
For example, the equation yields the following at a Vm: 1,000 [r/min], Ep: 300
[pulses/r], Pr: 0.01 [mm/pulse] and Er: ratio of 4.
1000 [r/min]

300 [ppr]

×
0.01 [mm/pulse]
÷
60 = 200 [mm/s]
Therefore, the setting range would be 1 to 200. When the minimum setting
unit is 0.01, the possible setting range would be 0.01 to 200.00.
In the example above, the display unit is mm. The SV unit would be pulses/s if
the display units were pulses.
Feed Rate Relationships
If the following conditions aren’t met, an error will occur when the parameters
are transferred from the CX-Motion.

Maximum Feed Rate/Maximum Interpolation Feed Rate/Maximum Jog Feed Rate
These parameters set the maximum feed rate for PTP operation, interpolation
operation, and jogging. Refer to
Feed Rate Setting Ranges
for more details on
possible ranges. Each axis used must be set individually.
