Dual Positioning
perform a positioning using two different velocities. The
first motion is done with the specified Vmin and Vmax
velocities in the SetDualPosition command, with the
acceleration (deceleration) parameter already in RAM, to a
position
SetDualPosition.
Remark: This operation cannot be interrupted or influenced by any further command unless the occurrence of the conditions
driving to a motor shutdown or by a HardStop command. Sending a SetDualPosition command while a motion is
already ongoing is not recommended. After dual positioning is executed the internal flag “Reference done” is set.
A SetDualPosition command allows the user to
1. The priority encoder is describing the management of states and commands.
2. If a SetPosition(Short) command issued during a DualPosition sequence, it will be kept in position buffer memory
3. Commands such as GetActualPos or GetStatus will be executed while a dual positioning is running. This applies also
4. A DualPosition sequence starts by setting TagPos buffer register to SecPos value, provided secure position is enabled
5. The acceleration/deceleration value applied during a DualPosition sequence is the one stored in RAM before the
6. The Pos1, Pos2, Vmax and Vmin values programmed in a SetDualPosition command apply only for this
7. Commands ResetPosition, SetDualPosition and SoftStop will be ignored while a DualPosition sequence is ongoing,
8. A SetMotorParam command should not be sent during a SetDualPosition sequence.
9. If for some reason ActPos equals Pos1[15:0] at the moment the SetDualPosition command is issued, the
