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

Creating a start program for the JOG operation

To perform the JOG 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 JOG operation is started for the axis 1. ([Cd.17]
JOG speed is set to 100.00 mm/min.)
Control data requiring settings
The following control data must be set to execute the JOG operation. The setting is executed with a program.
Setting item
[Cd.16] Inching movement amount
[Cd.17] JOG speed
For details on the settings, refer to the following.
Page 461 [Cd.16] Inching movement amount
Page 461 [Cd.17] JOG speed
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
I/O signals PLC READY signal
READY signal
Module access flag
Axis stop signal
Start complete signal
BUSY signal
Error detection signal
M code ON signal
External signal Drive unit READY signal
Stop 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
0 Set to "0" for JOG operation.
10000 Set a value that is equal to or larger than the value in
[Pr.7] Bias speed at start and also equal to or smaller
than the one in [Pr.31] JOG speed limit value.
Signal status
ON The CPU module is ready.
ON Positioning module READY.
*1
ON Positioning module buffer memory
access allowed.
OFF Axis stop signal is off.
OFF Start complete signal is off.
OFF Positioning module inactive.
OFF No error has been detected.
