Hpr Method (5): Scale Origin Signal Detection Method [Rj010 Mode] - Mitsubishi Electric MELSEC-Q Series User Manual

8.2.7 HPR method (5): Scale origin signal detection method [RJ010 mode]

The machine HPR is started.
(The machine begins the acceleration designated in "[Pr.51] HPR acceleration time selection", in the
1)
direction designated in "[Pr.44] HPR direction". It then moves at the "[Pr.46] HPR speed" when the
acceleration is completed.)
2) The machine begins decelerating when the proximity dog ON is detected.
After deceleration stop, the machine moves in the opposite direction against of HPR at the "[Pr.46] HPR
3)
speed".
4) During movement, the machine begins decelerating when the first zero signal is detected.
After deceleration stop, the operation moves in direction of HPR at the "[Pr.47] Creep speed", and then
5)
stops at the detected nearest zero signal.
The HPR complete flag ([Md.31] Status: b4) turns from OFF to ON, and the HPR request flag ([Md.31]
6)
Status: b3) turns from ON to OFF.

The following shows an operation outline of the "scale origin signal detection method"
HPR method.
POINT
Set "0: Need to pass servo motor Z-phase after power on" in "Function selection C-
4 (PC17)". If "1: Not need to pass servo motor Z-phase after power on" is set, the
error "Z-phase passing parameter invalid" (error code: 231) will occur at the start of
scale origin signal detection method HPR.

After 3), when the zero signal is in the proximity dog
position, deceleration stop (4)) is started at the zero signal
without waiting for the proximity dog OFF.
