Control Units During Machine Control - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

Control units during machine control

The interpolation control unit specified in the parameter block is checked with the interpolation control unit of the machine at
the Multiple CPU system power supply ON/reset, and at the start of machine program operation. The interpolation control unit
of the parameter block is set according to the specifications of the machine library.
At the Multiple CPU system power supply ON/Reset
When the interpolation control unit of the parameter block set in [Motion Control Parameter]  [Machine Control Parameter]
 [Machine Parameter]  "Machine Speed Setting"  "Parameter Block Designation" and the interpolation control unit of the
machine are different, a moderate error (error code: 30FAH) occurs and the machine does not start.
At the machine program operation start
When the interpolation control unit of the parameter block and interpolation control unit of the machine set in the machine
positioning data are different, a minor error (error code: 1FE0H) occurs and machine program operation does not start.

Starting method
• Starts when interpolation control units of the machine and
parameter block are the same
• Units are not converted when the interpolation control units
are different.
Does not start when interpolation control units of the machine
and parameter block are different.
