When the value is 0 in SR462, SR482, SR502, SR522, SR542, and SR562, it indicates the Pulse+direction output

mode. When the value is 1 in SR462, SR482, SR502, SR522, SR542, and SR562, it indicates the A/B phase

output mode.

Note: you can select the output mode only when D

direction output point.

When the direction outputs are not using the default outputs to output, you can refer to the table below for setting

up the outputting time that pulse outputting goes first before direction outputting does. So that you can be sure the

outputting only happens when switching to the direction outputs. The unit for SR is millisecond and the range is 0-

20 ms. Default is 0, indicating inactive.

Note: the time source here is from PLC scan time. (available for firmware version 1.02.20 or later)

When the output begins, the Busy flag SM is ON. When the output is completed, the Busy flag is automatically

reset to OFF and the Completion flag is not ON.

The following graph shows the output timing diagram. For the Busy flag in the following graph, refer to the Busy

You can modify the target output frequency during instruction execution but you can NOT change the ramp-up or

ramp-down time. When the new target frequency is greater than the previous one, the instruction uses the ramp-up

slope. When the new frequency is less than the previous one, the instruction uses the ramp-down slope.

The instruction sets the ramp-up/down slope through conversion of the set time and target frequency when the

instruction is executed. The slope does not change with the changing target frequency in the output process. For

example, the original target output frequency is 1 kHz and then it is modified to 2 kHz. The actual ramp-down time

uses an even output point and D

uses a recommended
