■ Preset Value
Set the Preset value Field to the desired preset value. The set value will be
stored in the Preset Value Register.
The following figure shows how the preset value works. In this example, a
fixed frequency is input from the encoder to the counter and the preset value
is set to 1000.
Count
Preset value = 1000
The preset value can be set to between –2,147,483,648 (8000 0000 hex) and
2,147,483,647 (7FFF FFFF hex).
This setting is stored in non-volatile memory. If the setting is changed, the new
value is effective immediately.

A Positioning Unit supports two comparison ranges, one for each digital out-
put. The tab page to set a comparison range is displayed only when the range
is enabled. Click the Range 0 or Range 1 Button on the Positioning Tab Page
to enable using the range and display the Range 0 or Range 1 Tab Page. The
digital output will not be controlled by the comparison function unless the cor-
responding range is set.
The Range 0 Tab Page is used to describe the functionality in this manual, but
the functionality is the same for range 1.
The digital output will be controlled by the corresponding range only when the
Output 0 Control Bits (bits 12 and 13 of word n+2) or Output 1 Control Bits
(bits 14 and 15 of word n+2) are OFF.
