Deflection Measurement Start (4000-series) (Sequence No. 435)

This sequence starts a deflection measurement.

Send Data Word Allocation (2nd Operand of PMCR)

None.

Receive Data Word Allocation (3rd Operand of PMCR)

None.

Note The deflection measurement keeps measuring until sequence No. 438 (Measurement Termination) is executed.

Continuous Measurement Start (Scan) (4000-series) (Sequence No. 436)

This sequence starts a continuous measurement. The scan notification method is used for the receive data.

Send Data Word Allocation (2nd Operand of PMCR)

None.

Receive Data Word Allocation (3rd Operand of PMCR)

The receive data word allocation is similar to that of sequence No. 434 (Single Run Measurement Start).

Note 1. Since this sequence repeats itself within the sequence, once it is executed, it remains in the execution state until cancelled.

2.Even if execution is cancelled, the Laser Micrometer still keeps measuring. Execute sequence No. 438 (Measurement Termination) to end the sequence.

Continuous Measurement Start (Interrupt) (4000-series) (Sequence No. 437)

This sequence starts a continuous measurement. The interrupt notification method is used for the receive data and the interrupt No. is 101.

Send Data Word Allocation (2nd Operand of PMCR)

None.

Receive Data Word Allocation (3rd Operand of PMCR)

The receive data word allocation is similar to that of sequence No. 434 (Single Run Measurement Start).

Note 1. Since this sequence repeats itself within the sequence, once it is executed, it remains in the execution state until cancelled.

2.Even if execution is cancelled, the Laser Micrometer still keeps measuring. Execute sequence No. 438 (Measurement Termination) to end the sequence.
