Example
Connection
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 FX
3G/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.

.b is available only in FX3U and FX3UC PLCs. However, index modifiers (V and Z) are not available.
4 : Only available for FX
3U and FX3UC PLCs.
8.3.2 List of Related Devices
1. Special auxiliary relays
The following table shows the related special auxiliary relays. Note that Y000, Y001, Y002, and Y003 are
devices that determine the pulse output destinations.
*1. Y002 is not available in 14-point and 24-point type FX3G PLC.
*2. Devices related to Y003 (pulse output destination) are only valid if two FX
3U-2HSY-ADP adapters are
connected to the FX
3U PLC.
*3. Cleared when the PLC switches from RUN to STOP.
