Command - Base Class Dynamic Variables

ID Label Type #Val Min Max Attr Description

12400

Command status word

Uint32

 

 

 

RO

Command generator status word. The following are the bit definitions:

   bit 0 - command generator in progress
   bit 1 - new setpoint is ready
   bit 2 - servo command done
   bit 3 - Cartesian trajectory mode active, keep interpreting setpoints even if "in motion" flag turned off and planned trajectory completed.
   bit 4:31 - (reserved)

NOTE: The "command done" flag simply means that the command generation is complete but does not mean that the motion is complete since the axis may still be in the process of settling to the final position.

12401

Position command, mcnt

Flt64

 

 

 

RO

Trajectory commands. Note that these values may come from different sources depending on the axis operation mode.

12402

Velocity command, mcnt/sec

Flt32

 

 

 

RO

12403

Acceleration command, mcnt/sec^2

Flt32

 

 

 

RO

12404

Torque command, tcnt

Flt32

 

 

 

RO

In the special case when the torque set point is directly commanded, this value represents the total received torque command. For example, if an axis is placed into AIN-torque mode and a torque command also comes from GPL directly, this value will be the sum of DataID 12441 and 12442.

12405

Setpoint time-stamp

Uint32

 

 

 

RO

Time-stamp of the incoming setpoint.

12406

Dynamic feedforward torque command, tcnt

Flt32

 

 

 

RO

For kinematic modules that generate Dynamic Feedforward torques, this parameter indicates the DFF torque command that was received from the Trajectory Generator, in tcnts.  Unlike the "Dynamic feedforward torque" (DataID 12337) that is only valid when a servo is in position control mode, this value is valid in any mode including torque control mode.  It displays the DFF value whether or not this value is added to the motor output.

12407

Command task time-stamp

Uint32

 

 

 

RO

Timestamp for testing the servo command task.
