CMPx.ADVANCE

Description

Use this keyword to compensate for slow output devices such as relays or mechanical devices. The value of this parameter determines how long in advance the compare engine will trigger to compensate for a slow output.

For example, if CMP0.ADVANCE = 10, and CMPx.SETPOINT = 1,000,000 counts while the source is moving at 100,000 counts/sec (positive direction), then the compare will trigger when the source value crosses 999,000 counts. This will be 1000 counts early, or 0.01 seconds of 100,000 counts/sec.

CMPx.ADVANCE has a 0.001 ms resolution.

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
FieldbusClosedA 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

EtherCATClosedEtherCAT 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
