Function and operation explanation
1. 16-bit operation (PLSR)
Pulses are output from output (Y) specified by by the number of output pulses specified by with
acceleration/deceleration to the maximum frequency specified by over the time (ms) specified by .
Refer to "Cautions" for setting , , and
.
2. 32-bit operation (DPLSR)
Pulses are output from output (Y) specified by by the number of output pulses specified by with
acceleration/deceleration to the maximum frequency specified by over the time (ms) specified by .
Refer to "Cautions" for setting , , and .
3. Pulse output specifications
• Simple positioning (with the acceleration/deceleration function)
The operation pattern is as shown below:
• Output processing
The pulse output is controlled by the dedicated hardware regardless of the operation cycle.
• Data change while the instruction is executed
Even if operands are overwritten while the instruction is executed, such changes are not reflected
immediately. The changes become valid the next time the instruction is driven.
