Data Setting Method - Mitsubishi Electric MELSEC iQ-R-RD75P4 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
• The OPR parameter areas ([Pr.43] 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. However, if a set value is outside the setting range and PLC READY
signal [Y0] is turned on, an error occurs and RD75 READY signal [X0] does not turn on. To avoid the occurrence of an error
when PLC READY signal [Y0] is turned on, Set values within the setting range (or initial 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.
