20.6 FNC157 – PLSV / Variable Speed Pulse Output
20.6 FNC157 – PLSV / Variable Speed Pulse Output
Outline
This instruction outputs variable speed pulses with an assigned rotation direction.
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 1, +1 to +32767 (except 0) Hz for 16-bit operation
Following range for 32-bit operation
3. Applicable devices
S1 : 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 FX3U PLC, a special high speed output adapter is required.
Outputs of special high speed output adapters work as differential line drivers.
S2 : When using a special high speed output adapter for the pulse output destination in an FX
3U PLC, the rotation
direction signal must be used by the following table output.
When using a built-in transistor output for the pulse output destination in an FX
3G/FX3U/FX3UC PLC, the rotation
direction signal must use transistor output.
S3:"D.b" is available only in FX
3U and FX3UC PLCs. However, index modifiers (V and Z) are not available.
S4 : This function is supported only in FX
3U/FX3UC PLCs.
