CMPx.WIDTH
Description
Use this keyword to set the width for a Compare setpointSetpoint is the target value that an automatic control system, for example PID controller, will aim to reach. 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 |
Hardware Supported
Compare functionality is supported on hardware revisions D, DB, DA, and higher depending on the drive type. Check the label on the side of the drive to ensure the AKD meets one of the following requirements.
AKD Type | Hardware Revision Supported |
---|---|
AKD | Revision D or higher |
AKD PDMM | Revision DB or higher |
AKD-T-IC"Integrated Circuits" Miniaturized electronic circuits (consisting mainly of semiconductor devices, as well as passive components) that have been manufactured in the surface of a thin substrate of semiconductor material | Revision DA or higher |
Variants Supported
