The BTUNE command is a motion buffer command that starts a 2-axis circular interpolation motion.  Circles can be drawn using 2 axes in either the CW or CCW direction.  All circular moves are interpreted as absolute moves.

Applies to: V300+ CMD-4CR, CMD-4EX-SA

Syntax

Write

       CIR[A1][A2]P[C1]:[C2]         for CW motion

CIR[A1][A2]N[C1]:[C2]         for CCW motion

Where:        [A1][A2]   specifies axis 1 and axis 2 (X, Y, Z, U),
               N is CCW motion, P is CW motion,
               [C1]:[C2] specifies the circle coordinate center of [A1],[A2] (32-bit value)

Command cannot be processed

       An error message is returned. See Error Codes

Example 

Write

CIRXYP1000:0        * Circular interpolation of X and Y axis, center X = 1000, Y = 0 move in CW direction

Write

       CIRN1000:0        * Circular interpolation of X and Y axis, center X = 1000, Y = 0 move in CCW direction

Notes

  • Any axis can be used for circular interpolation operations.
  • Other conditions:

Joystick operation is disabled

Manual pulse generator (MPG) operation is disabled

Current operations are stopped

Error status is off
