8 OPR CONTROL
8.2.2 Machine OPR method
The method by which the machine OP is established (method for judging the OP position and
machine OPR completion) is designated in the machine OPR according to the configuration
and application of the positioning method.
The following table shows the methods that can be used for this OPR method.
(The OPR method is one of the items set in the OPR parameters. It is set in "
Pr.43
OPR
method" of the basic parameters for OPR.)
Pr.43
OPR method
Operation details
Near-point dog method
Deceleration starts by the OFF
ON of the near-point dog. (Speed is reduced to
" Pr.47 Creep speed".)
The operation stops once after the near-point dog turns ON and then OFF. Later the
operation restarts and then stops at the first zero signal to complete the OPR.
Count method 1)
The deceleration starts by the OFF
ON of the near-point dog, and the machine moves
at the " Pr.47 Creep speed".
The machine stops once after moving the distance set in the " Pr.50 Setting for the
movement amount after near-point dog ON" from the OFF
ON position. Later the
operation restarts and then stops at the first zero signal to complete the machine OPR.
Count method 2)
The deceleration starts by the OFF
ON of the near-point dog, and the machine moves
at the " Pr.47 Creep speed.
The machine moves the distance set in the " Pr.50 Setting for the movement amount
after near-point dog ON" from the near-point dog OFF
ON position, and stops at that
position. The machine OPR is then regarded as completed.
Data set method
The position where the machine OPR has been performed becomes an OP.
The current feed value and feed machine value are overwritten to the OP address.
REMARK
Creep speed
The stopping accuracy is poor when the machine suddenly stops from fast speeds. To
improve the machine's stopping accuracy, its must change over to a slow speed before
stopping. This speed is set in the "
Pr.47
Creep speed".
