Hpr Method (4): Data Set Method [Rj010 Mode] - Mitsubishi Electric MELSEC-Q Series User Manual

8.2.6 HPR method (4): Data set method [RJ010 mode]

The following shows an operation outline of the "data set method" HPR method.
The "Data set method" method is effective when a "Proximity dog" is not used.
It can be used with absolute position system.
With the data set method HPR, the position where the machine HPR has been carried
out, is registered into the Simple Motion module as the HP, and the feed current value
and feed machine value is overwritten to an HP address.
Use the JOG or manual pulse generator operation to move the HP.

Precautions during operation
(1) The zero point must have been passed before the HPR is carried out after the
power supply is turned ON. If the HPR is carried out without passing the zero
point even once, the error "HPR zero point not passed" (error code: 210) will
occur. When the error "HPR zero point not passed" (error code: 210) occurs,
perform the JOG or similar operation so that the servomotor makes more than
one revolution after an error reset, before carrying out the machine HPR again.
However, if selecting "1: Not need to pass servo motor Z-phase after power
on" with "Function selection C-4 (PC17)", it is possible to carry out the home
position return (HPR) without passing the zero point.
(2) The HPR data used for the data set method is the "HPR direction" and "HP
address".
The HPR data other than that for the HPR direction and HP address is not
used for the data set method HPR method, but if a value is set the outside the
setting range, an error will occur when the PLC READY signal [Y0] is turned
ON so that the READY signal [X0] is not turned OFF.
With the HPR data other than that for the HPR direction and HP address, set
an arbitrary value (default value can be allowed) within each data setting
range so that an error will not occur upon receiving the PLC READY signal
[Y0] ON.
