Write/Read Method For Command Generation Axis Parameter And Positioning Data - Mitsubishi Electric MELSEC iQ-F FX5 Series User Manual

Write/read method for command generation axis parameter and
positioning data
The command generation axis parameter and positioning data are not stored in the buffer memory, so that each setting value
changes by the control data. The fetch timing of each parameter and positioning data is in accordance with each specification.
Therefore, some parameter is not used for control until PLC READY ON or the power supply ON.
• Execute the writing of the parameter and positioning data by the write method procedure shown below. If
the writing order is wrong, an unpredictable value might be set.
• The command generation axis control data and positioning data written by this method are erased at the
power supply OFF. When it is necessary to save the data, write to the flash ROM of the Simple Motion
module/Motion module by "[Cd.1] Flash ROM write request".
Write method for command generation axis parameter
1.
Specify the command generation axis parameter No. to "[Cd.300] Command generation axis parameter No.
designation".
2.
When "340" is set, "[Pr.340] Command generation axis valid setting" is specified. When "1" is set, "[Pr.1] Unit setting" is
specified.
3.
Specify the setting value to the command generation axis parameter with 2 words in "[Cd.301] Command generation axis
parameter setting value".
4.
Set "1: Write request" to "[Cd.302] Command generation axis parameter control request".
5.
"[Cd.301] Command generation axis parameter setting value" is written to the command generation axis parameter No.
specified in "[Cd.300] Command generation axis parameter No. designation". When the writing is succeeded, "0: Not
request" is set in "[Cd.302] Command generation axis parameter control request".
6.
When the parameter No. which is not defined to the command generation axis is specified, "FFFFH: Write/read error" is
set in "[Cd.302] Command generation axis parameter control request". "[Cd.302] Command generation axis parameter
control request" is detected always. It is not required to return to "0: Not request" from "FFFFH: Write/read error"
manually.
7.
The command generation axis control data and positioning data written by this method are erased at the power supply
OFF. When it is necessary to save the data, write to the flash ROM of the Simple Motion module/Motion module by
"[Cd.1] Flash ROM write request".
The timing that the command generation axis parameter to be written becomes valid is common with the servo amplifier axis.
For specification details, refer to "MAJOR POSITIONING CONTROL" in the following manual.
