1 : Specify Y000, Y001 or Y002
from a high-speed output special adapter
*1. Y002 is not available in 14-point and 24-point type FX
*2. High-speed output special adapters can be connected only to FX
*3. To use Y002 or Y003 with a high-speed output special adapter, connected a second high-speed output
special adapter.
Points
• When using a relay output type or triac output type FX
required.
• Outputs of special high-speed output adapters work as differential line drivers.
→ For explanation of the instruction, refer to the Positioning Control Edition manual.
