[Pr.43] HPR method
Set the "HPR method" for carrying out machine HPR.
0: Proximity dog method [RJ010 mode]
...... After decelerating at the proximity dog ON, stop at the zero signal and
complete the machine HPR.
4: Count method 1) [RJ010 mode]
...... After decelerating at the proximity dog ON, move the designated distance,
and complete the machine HPR with the zero signal.
5: Count method 2) [RJ010 mode]
...... After decelerating at the proximity dog ON, move the designated distance,
and complete the machine HPR.
6: Data set method [RJ010 mode]
...... The position where the machine HPR has been made will be the HP.
7: Scale origin signal detection method [RJ010 mode]
...... After deceleration stop at the proximity dog ON, move to the opposite
direction against the HPR direction, and move to the HPR direction after
deceleration stop once at the detection of the first zero signal. Then, it
stops at the detected nearest zero signal, and completes the machine
HPR.
8: Driver HPR method [CiA402 mode]
...... Carry out the HPR operation on the driver side. The HPR operation and
parameters depend on the specifications of the driver.
Refer to Section 8.2.8 "Driver HPR method" for details.
When HPR method that cannot be executed is set, the error "HPR method invalid"
(error code: 232) occurs and the HPR is not executed.
Note) Refer to Section 8.2 "Machine HPR" for details on the HPR methods.
