5 Common Command Instructions

Function

• When Execute changes to TRUE, the MC_ReadAxisParameter instruction reads the axis parameters
of the axis specified with Axis and outputs them to AxisParameter (Axis Parameters).
• You can use this instruction to read the axis parameters regardless of the status of the Cfg.AxEnable
(Axis Use) axis variable.
Precautions for Correct Use Precautions for Correct Use
• This instruction reads the values of the axis parameters that are valid when the instruction is
executed, and not the values that are saved in the non-volatile memory of the CPU Unit.
For example, if you write the axis parameters with the MC_Write (Write MC Setting) instruc-
tion, the written axis parameters are read.
• If you use this instruction together with the MC_WriteAxisParameter (Write Axis Parameters)
instruction, check Done from the MC_WriteAxisParameter (Write Axis Parameters) before you
read the axis parameters.
• The values of the axis parameters are output to AxisParameter (Axis Parameters) only at the
completion of instruction execution. They are not written to AxisParameter (Axis Parameters)
after that. Therefore, if you write values to AxisParameter (Axis Parameters), the previous val-
ues are overwritten.
Axis Parameters That Are Read
Refer to Axis Parameters That Are Written and Read on page 5-58 for the parameters that are read by
this instruction.
