7. AUXILIARY FUNCTION

7.6.4 Interrupt processing example

Write the interrupt signal

clear register (Note 2)

Set an event for the interrupt

service routine (ISR)

Interrupt Handler

CH number S 1

Yes

CH number S S 1

Is the maximum number

of CH S?

Finish

Capture of system interrupt factors

and interrupt factors for each axis

Execution of processing for each

cause for interrupt (Note 3)

Yes

Turn on the interrupt processing

complete signal (ITE)

Waiting for setting of event

from interrupt handler

Interrupt service routine

(ISR)

Is the outputting with

factor of interrupt (ITO) OFF?

Is the during

interrupt output signal

(Note1) for CH number

S ON?

Note 1. Confirm the bit(s) for the during interrupt output signal (address 20004h on the dual port memory).

(If the bit(s) are on: a current interrupt is being output, while if the bit(s) are OFF: there is not a current interrupt)

2. When 1 is written in the interrupt signal clear register (address 20008h (CH1) on the dual port memory), the output of the

interrupt is cancelled.

3. Implement processing necessary for the different causes of interrupts, such as for completion of operation and generation of an

operation alarm.
(example) When an operation alarm occurs, send a stop request to other axes that are in operation.

API LIBRARY

This interrupt processing example is processed by the device driver thus

processing by user program is unnecessary.
