■Change command generation axis parameters and positioning data
The command generation axis does not store parameters or positioning data in the buffer memory. Therefore, rewrite the
parameters and the positioning data using the following methods.
• When using GX Works3
Set the command generation axis parameters and positioning data using GX Works3. After that, execute writing to the Simple
Motion module or writing to the Motion Module.
• When using command generation axis control data
[Change command generation axis parameters]
Use the following control data. For details, refer to Page 52 Write/read method for command generation axis parameter
and positioning data.
[Cd.300] Command generation axis parameter No. designation
[Cd.301] Command generation axis parameter setting value
[Cd.302] Command generation axis parameter control request
[Change command generation axis positioning data]
Use the following control data. For details, refer to Page 52 Write/read method for command generation axis parameter
and positioning data.
[Cd.303] Command generation axis positioning data No. designation
[Cd.304] Command generation axis positioning data designation
[Cd.305] Command generation axis positioning data setting value
[Cd.306] Command generation axis positioning data control request
■Setting for command generation axis
Set "1: Valid" in "[Pr.340] Command generation axis valid setting" using the methods above. The command generation axis
setting is fetched at the power ON. Therefore, to disconnect the command generation axis, turn ON the Motion module power
supply again after setting "0: Invalid" in "[Pr.340] Command generation axis valid setting".
■Start request
Specify the positioning data No. in "[Cd.3] Positioning start No." and set "1: ON" in "[Cd.184] Positioning start". The start
complete signal ([Md.31] Status: b14) and "[Md.141] BUSY" turn ON, and the positioning operation starts.
■Available data
The buffer memory addresses are different for the data available for servo amplifier axes and command generation axes.
Refer to "List of Buffer Memory Addresses" in the following manual for the buffer memory addresses for servo amplifier axes.
MELSEC iQ-R Motion Module User's Manual (Application for Simple Motion Mode)
For the buffer memory addresses of the command generation axis, refer to the following.
Page 167 List of Buffer Memory Addresses (for Synchronous Control)
■Troubleshooting
Output the axis error and warning which are same as the servo amplifier axis to "[Md.23] Axis error No." and "[Md.24] Axis
warning No." of the command generation axis.
