CMPx.WIDTH

Description

Use this keyword to set the width for a Compare setpointClosed Setpoint 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

General Information

Type

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

Start Version

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-ICClosed "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

*In SynqNetClosed SynqNet is a digital machine control network. Built on the 100BT physical layer, SynqNet provides a synchronous real-time connection between motion controllers, servo drives, stepper drives, I/O modules, and custom devices, a parameter may be available in the firmware but have no effect on the system. See SynqNet Supported Parameters.

FieldbusClosed A Fieldbus is an industrial network system for real-time distributed control (e.g. CAN or Profibus). It is a way of connecting instruments in a plant design Index/Subindex Object Start Version

EtherCATClosed ***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs COE and CANopen
