Creating A Start Program For The Inching Operation - Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual

Creating a start program for the inching operation

To perform the inching operation, create a program. When creating a program, consider Control data requiring settings, Start
condition, and Start time chart. The following shows an example when the inching operation is started for the axis 1. ([Cd.16]
Inching movement amount is set to 10.0 μm.)
Control data requiring settings
The following control data must be set to execute the inching operation. The setting is executed with a program.
Setting item
[Cd.16] Inching movement amount
For details on the settings, refer to the following.
Page 461 [Cd.16] Inching movement amount
Start condition
Satisfy the following conditions to start a program. In addition, set the required conditions in the program to prevent an
operation from starting if the conditions are not satisfied.
Signal name
Interface signal PLC READY signal
READY signal
Module access flag
Axis stop signal
Start complete signal
BUSY signal
Positioning complete signal
Error detection signal
M code ON signal
External signal Drive unit READY signal

Upper limit (FLS)
Lower limit (RLS)
*1 To access the buffer memory, the interlock must be provided so that the buffer memory can be accessed after Module access flag
([Md.140] Module status: b1) turns on. When no interlock is provided, the buffer memory may be accessed while the module parameter
and module extension parameter that are sent from the CPU module are updated. If the buffer memory is accessed during the update,
an unexpected value may be read or written.
Setting Setting detail
value
100 Set a setting value so that the command pulse is not
larger than the maximum output pulse.
Maximum output pulses: 200 kpulse/s
