SDIR (direction of rotation)
This parameter determines the direction of rotation with which the drilling operation is carried
out in the cycle.
If values other than 3 or 4 (M3/M4) are generated, alarm 61102 "No spindle direction
programmed" is generated and the cycle is aborted.
Programming example: Third boring
CYCLE87 is called at position X0 in the XY plane. The drilling axis is the Z axis. The final
drilling depth is specified as an absolute value. The safety clearance is 2 mm.
