FNC158 – DRVI / Drive to Increment
Outline
This instruction executes one-speed positioning by incremental drive. The movement distance from the present
position can be specified, positive or negative.
→
For explanation of the instruction, refer to the Positioning Control Edition manual.
→
For cautions on using special high-speed output adapters,
refer to the Positioning Control Edition manual.
1. Instruction format
2. Set data
*1.
Setting range:
−
32768 to +32767 (except 0) for 16-bit operation
−
999,999 to +999,999 (except 0) for 32-bit operation
*2.
Setting range: 10 to 32767 Hz for 16-bit operation
Following range for 32-bit operation
3. Applicable devices
S
1 : Specify Y000, Y001 or Y002
*1
transistor output from the main unit, or specify Y000, Y001, Y002
*3
, or Y003
*3
from a high-speed output special adapter
*2
.
*1.
Y002 is not available in 14-point and 24-point type FX
3G
PLC.
*2.
High-speed output special adapters can be connected only to FX
3U
PLC.
*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
3U
PLC, a special high-speed output adapter is
required.
• Outputs of special high-speed output adapters work as differential line drivers.
