Control precautions
• Even if the same interrupt factor occurs again while [Md.65] Interrupt factor detection flag is 1: Interrupt factor detected, no
interrupt request is sent to the CPU module.
• While [Cd.50] Interrupt factor mask is 0: Mask, no interrupt request is sent to the CPU module.
• After the power is switched on or the CPU module is reset, no interrupt request is sent to the CPU module because the
interrupt parameter in the RD75 is set to the initial value. Turn off and on PLC READY signal [Y0] to validate the interrupt
parameter.
• Starting "Positioning Test" of the engineering tool validates the interrupt parameter at a start.
• If a parameter error occurs when PLC READY signal [Y0] is turned off and on or "Positioning Test" of the engineering tool is
started, the interrupt parameter is invalidated. No interrupt request is sent to the CPU module.
Operation example
The following shows an example of the interrupt factor setting and the operation in which the interrupt program of the interrupt
pointer I50 is executed if the interrupt factor is detected.
For details on the interrupt pointer I50, refer to the following.

[Pr.900] Interrupt factor setting

[Pr.901] Axis No. for interrupt factor 1 1: Axis 1 55259
(1) Configure the interrupt setting using an engineering tool and create the processing for Axis 1 command in-position in the I50 program. Write the project
and validate the setting.
(2) In the normal control program, set [Cd.50] Interrupt factor mask (address: 55067) to 1: Clear mask.
(3) When the remaining distance of the axis 1 falls within the range specified by the command in-position width setting value, [Md.65] Interrupt factor
detection flag (address: 55003) of setting 4 turns to 1: Interrupt factor detected at the same time when b2: Command in-position of [Md.31] Status turns
on.
(4) The interrupt pointer I50 program of the CPU module is started.
(5) When [Cd.51] Interrupt factor reset request of setting 4 (address: 55131) is set to 1: Reset request, the interrupt factor is cleared and 0: Interrupt factor
not detected is stored in [Md.65] Interrupt factor detection flag of setting 4 (address: 55003).
