As can be seen  above, if EtherNet/IP is used it will overwrite any of the other protocols in a write operation. The other protocols can still be used for read operations and diagnostics.

TargetPositionP14102940-730-3

The target position the motor will move to.

  • Used as an absolute position
  • Used as an incremental position in a relative control(1) move
  • Not used in speed control(1)

(1) See the Controlword for switching to speed or relative control.

TargetSpeedS14103184-1174-7

The maximum speed of the profile trajectory.

  • the sign of S1 is ignored in a position control move.
  • +ve S1 in speed control will run the motor in a +ve direction (typically CW)
  • -ve S1 in speed control will run the motor in a -ve direction (typically CCW)
TargetTorqueN141033128-1398-9The maximum torque the motor will use.
TargetAccelerationA1410351410-151110-11

Acceleration is used when the profile is accelerating to the target speed.
This is regardless of whether the target speed will be reached or not

TargetDecelerationA2410371612-171312-13Deceleration is used when the profile is decelerating to the target position.

Torque Mode
Anchor
Torque
Torque

Torque mode would be used where there is no target position but the motor is required to continuously hold or move at a required maximum torque. In this mode the toque set is a maximum torque and the torque will only be reached if required.

Torque mode uses some specific bits in the Controlword

BITNameValueDescription
B0Start/New Set Point

0

  • Do not follow the N1 target torque
  • Target Speed S1 is still executed
  • Do not start a new torque move
0 → 1
  • Start a torque move defined by the torque registers
  • 0 → 1 transition is required to start a torque move after
    • an error has been cleared
    • a home has been completed
    • a stop command has been given from CML or an input.
1

Following N1 target torque

B1Halt0Do nothing
1
  • Halt all motion and inhibit further motion
  • Halt all torque related parameters (torque & speed)
B3-B2N/A
B7-B4See Controlword

The interaction of the halt bit and the new set point (nsp) bit is quite specific. See the table below for additional important interaction.

B0 (nsp) B1 (Halt)Description
10Motion profile follows torque and speed values
10 → 1

All motion stops

11

Motion is inhibited

  • Changes in speed are NOT followed
  • Changes in torque are NOT followed
01Operation is the same as above.
00

Motion may resume based on values

  • Torque will NOT be updated
  • Motion will continue if speed > 0


Note

It is important to understand that the halt bit temporarily halts operation. It does not interrupt motion. This means that a rising edge (0 → 1) is not required on B0 to continue operation. To keep prohibiting motion the following could be use

  • Keep the halt bit at 1
  • Set target velocity = 0
  • Move out of torque mode
