CMPx.WIDTH
Description
Use this keyword to set the width for a Compare setpoint. The width defines for how much time or for how many position counts a pulse will be generated once a setpoint is active.
If a pulse width's type is in microseconds, the resolution is as follows:
| Width | Resolution |
|---|---|
| 0 to 65,535 μs | μs |
| 65,536 μs to 65.535 s | ms |
CMPx.WIDTH must be set before CMPx.SETPOINT.
Example
The following example sets the width type of setpoint 7 to microseconds, and the width of setpoint 7 to 1000 microseconds.
-->CMP0.WIDTHTYPE 7 1
-->CMP0.WIDTH 7 1000

Units
If CMPx.WIDTHTYPE = 0 (position counts),determine units with the following table.
| CMPx.SOURCE | Units |
|---|---|
| 0 (FB1) | Depends on FB1.PUNIT or custom units. |
| 1 (FB2) | Depends on FB2.PUNIT or custom units. |
| 2 (FB3) | Depends on FB2.PUNIT or custom units. |
| 3 (PL.FB) | Depends on UNIT.PLINEAR
or UNIT.PROTARY
Rotary: counts, rad, deg, (custom units), 16-bit counts Linear: counts, mm, µm, (custom units), 16-bit counts |

| AKD Type | Hardware Revision Supported |
|---|---|
| AKD | Revision D or higher |
| AKD PDMM | Revision DB or higher |
| AKD-T-IC | Revision DA or higher |
Variants Supported
| Variant | Supported |
|---|---|
| AKD Base | No |
| AKD with Position Indexer | No |
| AKD EtherCAT | Yes |
| AKD CANopen | Yes |
| AKD BASIC | Yes |
| AKD SynqNet | See SynqNet Supported Parameters |
| AKD EtherNet/IP | Yes |
| AKD Profinet | Yes |
| AKD sercos® III | Yes |
| AKD-N | No |
