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

General Information

NV Parameter

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

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 Revision DA or higher

Variants Supported

Variant Supported
AKD Base No

*In SynqNet, a parameter may be available in the firmware but have no effect on the system. See SynqNet Supported Parameters.

Fieldbus Information

If your drive type is listed as supported but no index, address, or instance number is listed, then this parameter is accessible through WorkBench, but not over your fieldbus type. For information on SynqNet parameters see SynqNet Supported Parameters.
