Data Setting Method - Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual

Data setting method

Data setting method is used to set a point at which the workpiece is positioned by a manual feed such as JOG operation as an
OP.
When the machine OPR is performed using the data setting method, Deviation counter clear signal is output to the drive unit
and the current feed value and machine feed value are overwritten with the OP address.

Operation precautions
• If not using the OP shift function, the OPR parameter areas ([Pr.44] to [Pr.57]) other than "[Pr.45] OP address" and "[Pr.55]
Deviation counter clear signal output time are not used for the data setting method. If a value outside the settings range is
set, however, an error occurs when "[Cd.190] PLC READY signal" is turned ON, and the READY signal ([Md.140] Module
status: b0) does not turn ON. To avoid the an error occurring when "[Cd.190] PLC READY signal" is turned ON, set values
within the setting range (or default values) for the unused OPR parameter areas.
• When performing an OPR operation using Data setting method for a device for which the backlash compensation function
is used, perform the manual control beforehand. Otherwise the backlash compensation cannot be properly executed.
