GANTRY.STATE

Description

State  
GANTRY.STATE 0 Each axis is individually controlled.
GANTRY.STATE 1 Gantry is pending successful homing.
GANTRY.STATE 2 Gantry Mode is pending successful re-homing.
GANTRY.STATE 3 Gantry Mode is active, issue commands on Axis 1.

By default, a dual axis drive is configured for each axis to be individually controlled. In this mode, GANTRY.STATE = 0.

When an axis is put into Gantry Mode (AXIS#.CMDSOURCE = 4), the Gantry is configured but full gantry mode cannot occur until both axes have been homed. In this mode GANTRY.STATE = 1. Amp Enable is now controlled through Axis 1, but both axes are running their own trajectories until both axes have been successfully homed.

As soon as both axes have been successfully homed, GANTRY.STATE will be 2 indicating Gantry mode is active and now all motion is controlled through Axis 1 under a single trajectory generator.

If any axis has its home offset cleared (AXIS#.HOME.CLEAR) homing will need to be completed for both axes again.

Fieldbus Information

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 Parameter Index Sub-Index Data Type Float Scale Units Access PDOClosed PDO is a type of protocol frame used in some fieldbuses. A PDO contains one or more object dictionary entries, which define the application data transferred between devices. Mappable
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 GANTRY.STATE 0x300E:5 (no unit scaling, integer) 0x4 INT 1:1 - RW False
