CMPx.WIDTH

General Information
Type	NV Parameter
Description	Sets the width for a Compare setpointSetpoint is the target value that an automatic control system, for example PID controller, will aim to reach.
Units	Position counts or microseconds depending on CMPx.WIDTHTYPE. If CMPx.WIDTHTYPE = 0 (position counts), then units depend on CMPx.SOURCE (see table below).
Range	Argument 1: 0 to 7 Argument 2: 0 to 18,446,744,073,709,551,615 (position counts) or 0 to 65,535,000 (microseconds)
Default Value	0
Data Type	Argument 1:Integer Argument 2: Integer
Start Version	M_01-13-00-000

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

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
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

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
