4.1.2 Special Data Registers

The following table shows the related special data registers. Note that Y000, Y001, Y002, and Y003 are

devices that determine the pulse output destinations.

*1. Devices related to Y003 (pulse output destination) are only valid if two FX3U-2HSY-ADP adapters are connected to the

FX3U PLC.

*2. Only available for FX3U/FX3UC PLC Ver. 1.30 or later.

However, the user interrupt input command can be specified only if the FX3U/FX3UC PLC Ver.2.20 or later is used.

*3. This instruction is valid only during acceleration/deceleration supported in the FX3U/FX3UC PLC Ver. 2.20 or later and

FX3G PLC.

*4. Only available for FX3U/FX3UC PLC Ver. 2.20 or later and FX3G PLC.

*5. Y002 (pulse output destination) cannot be specified when the 14-point or 24-point type FX3G PLC is connected.
