*1. Y002 is not available in FX3G PLC (14-point and 24-point type) and FX3S/FX3GC PLC.

*2. Y003 is available only when two high-speed output special adapters are connected to the FX3U PLC.

*3. This instruction is not supported in the FX3S PLC.

*4. Only available for FX3U and FX3UC PLCs.

*5. 32 bits are used for the maximum speed setting device and the zero return speed setting device.

*6. Set this item by selecting "PLC Parameter" → "Positioning Instruction Settings" of GX Works2 in the FX3UC PLC Ver. 2.20 or later or FX3G/FX3GC/FX3U PLC.

The data set by the parameter will be stored in the corresponding setting device.

*7. To accelerate or decelerate the operation using the variable speed pulse output (PLSV) instruction with an FX3UC PLC Ver. 2.20 or later and FX3S/FX3G/FX3GC/FX3U PLC, it is necessary to set this item.

If the operation is not accelerated or decelerated, or if an FX3UC PLC below Ver. 2.20 is used, the PLSV instruction will not use this item even if it is set.

*8. The ZRN instruction will not use any zero return direction setting devices. Using the program, adjust the rotation direction output to the zero return direction.

*9. This item can be set using an FX3UC PLC Ver. 2.20 or later and FX3S/FX3G/FX3GC/FX3U PLC.

*10. Only available for FX3UC PLC Ver. 1.30 or later and FX3U PLC.

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

*11. Use this function only if immediate stop is absolutely needed to avoid danger.
