specified.
M-code listed below is commanded in same block with T-code or previous block with
T-code. Rotating direction M-code commanded once is valid in only one T-code. In
case of commanding T-code again after turret rotating, turret will be rotates in the
direction of the short distance normally. And rotating direction determination function
by M-code is only valid in automatic mode.

Above M-code can be used in case that interference occurs when special tool
attached to tool holder and turret is rotated in the specific direction.
Example → Current tool no. is 5.
