3U PLC.
*3. This instruction is not supported in the FX
3S PLC.
*4. Only available for FX
3U 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
FX
3UC 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 FX
3UC 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 FX
3UC PLC below Ver. 2.20 is used, the
PLSV instruction will not use this item even if it is set.
