12 CONTROL SUB FUNCTIONS
[2] Precaution during control
(1) The following table shows whether the OPR retry function may be executed
by the "
Pr.43
OPR method".

(2) Always establish upper/lower limit switches at the upper/lower limit positions
of the machine, and connect an QD75 module. If the OPR retry function is
used without hardware stroke limit switches, the motor will continue rotation
until a hardware stroke limit signal is detected.
(3) Always wire QD75 upper/lower limit switches even when the OPR function
is invalidated. Control cannot be carried out with the QD75 unless the wiring
is carried out.
(4) Do not carry out settings so that the servo amplifier power turns OFF by the
upper/lower limit switches connected to the QD75. If the servo amplifier
power is turned OFF, the OPR retry cannot be carried out.
(5) The operation decelerates upon detection of the hardware limit signal, and
the movement starts in the opposite direction. In this case, however, an
error (104, 105) is not produced.
[3] Setting the OPR retry function
To use the "OPR retry function", set the required details in the parameters shown
in the following table, and write them to the QD75.
When the parameters are set, the OPR retry function will be added to the
machine OPR control. The set details are validated at the rising edge (OFF
ON) of the PLC READY signal (Y0). Set "
Pr.57
Dwell time during OPR retry"
according to the user's requirements.

Refer to Section 5.2 "List of parameters" for setting details.
REMARK
•
Parameters are set for each axis.
•
It is recommended that the parameters be set whenever possible with GX
Configurator-QP. Execution by PLC program uses many PLC programs and
devices. The execution becomes complicated, and the scan times will increase.
