8.3.1 Instruction Format
1. Instruction format
2. Data setting
*1. Setting range : -32,768 to +32,767 for 16-bit operation
: -999,999 to +999,999 for 32-bit operation
*2. Setting range : 10 to 32,767 Hz for 16-bit operation
For 32-bit operation, however, the setting range is as shown in the following table.
3. Devices
1 : Specify Y000, Y001, or Y002
*3
transistor output from the main unit, or specify Y000, Y001, Y002
*5
, or
Y003
*5
from a high-speed output special adapter
*4
.
*3. Y002 is not available in FX
3G PLC (14-point and 24-point type) and FX3S/FX3GC PLC.
*4. High-speed output special adapters can be connected only to the FX
3U PLC.
*5. To use Y002 and Y003 with a high-speed output special adapter, connect a second high-speed output
special adapter.
Caution:
• To use an FX
3U PLC of relay output type or triac 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.
