1,2,3... 1. Set in A1999. (Use CX-Motion to set 34231201 directly or set it with the
following ladder program.)
2. Select the customized functions. See “Customized Functions” on page 45.
3. Enable output.
Application
Precautions
• The settings in A1999 are read when the IOWR instruction is used to
select the customized functions. Once set, the settings cannot be
changed.
• Changes to the zone parameters are read in real time. The settings in the
negative and positive directions cannot be changed at the same time. If
there is a possibility that unexpected outputs will be produced when a
zone is being changed, turn OFF the General-purpose Output Bits (allo-
cated word n, bits 0 to 3) before changing the zone.
Note With the CX-Motion, both the positive and negative settings can be down-
loaded at the same time. There are, however, subtle differences in the timing
for reading these at the MC Unit, so the above precaution applies even when
downloading zone settings from the CX-Motion.
• The response time for changing zone parameters and General-purpose
Output Bits (allocated word n, bits 0 to 3) depends on Unit status. Approx-
imately 10 ms is required.
