1 : Specify Y000, Y001, or Y002 transistor output from the main unit, or specify Y000, Y001, Y002*2, or

Y003*2 from a high-speed output special adapter*1.

*1. A high-speed input/output special adapter cannot be connected to the FX3UC PLC.

*2. To use Y002 and Y003 with a high-speed output special adapter, connect a second high-speed output

special adapter.

Point:

• To use an FX3U Series main unit of relay output type, be sure to connect a high-speed output special

adapter. Differential line drive type outputs will be used for the outputs of the high-speed output special

adapter.

2 : When a high-speed output special adapter is used as a destination for pulse output on a FX3U PLC,

use the output shown in the following table for rotation direction signals.

When a built-in transistor output is used as a destination for pulse output on a FX3U/FX3UC PLC, use

transistor output for signals rotation direction.

→ For the outputs applicable with a High-speed output special adapter, refer to Section 4.9.

3:D.b cannot be indexed by index registers (V and Z).
