By making the intelligent function module switch setting, the QD70 allows you to set
the pulse output mode, external I/O signal logic and rotation direction. (However, you
cannot set the speed-position switching signal (CHG) logic. It is fixed at the negative
logic.)
Make the intelligent function module switch setting in the "I/O assignment setting" PLC
parameter of the QCPU using GX Developer.
• There are intelligent function module switches 1 to 5, which are set with 16-bit data.
• When you do not make the intelligent function module switch setting, switches 1 to 5
default to 0.
The settings made with the intelligent function module switches are made valid after
power-on or programmable controller CPU reset. You cannot change the settings
during operation.
