Write an ON pulse width value to the D register in the table below. The data type is
integer.

(2)

After writing that value, write 1 to the pulse output writing status register, D0211.

NOTE

When the value to be set for the ON pulse width is greater than the value calculated by the
following equation, the value cannot be set:

are validated)

Effective Range

Unit:

ϫ

10 ms

If other than 1: Invalid
If 1: Writing is executed

Initial value of ON pulse width: 5 (50 ms)

[Example]

To set the ON pulse width to 100 ms, write “000A.”

For station number 01, use PC link communication (without checksum) and the random
write command as shown below:

[Command]

[STX] 01010WRW02D0210, 000A, D0211, 0001 [ETX] [CR]

[Response]

[STX] 0101OK [ETX] [CR]

NOTE

An ON pulse width value can be set for the PR300 with pulse output.

To set the ON pulse width value via communication, set it to 1/10 the value of the
displayed (true) value (e.g., set it to 5 when setting the ON pulse width value to 50
ms).
