Character: q
Decimal: 113
Hexadecimal: 0x71
Command Value: New Position
Command Value (Resolver): Not used
This command is used to put a quadrature encoder axis into a known state. The COMMAND POSITION, TARGET POSITION and ACTUAL POSITION are set to the value specified in the Command Value register. The axis is placed in the closed loop position control state and error bits in the status word are cleared.
Note: If the axis is in motion or in Open Loop before this command is given, it will come to an immediate stop and hold the specified position. If the axis is controlling pressure, the positions will be reset but the pressure control will not be interrupted.
Resolver Axes
This command will determine the axis absolute position within one turn of the resolver and set the Actual Position to that value. If the position had previously incremented through several turns, all the turns will be unwound (without causing motion). If the axis is moving when this command is issued, the axis will come to a stop and will hold position in closed loop position control.
See the Resolver Overview topic for a description of how the absolute position is determined.
