– 290 –
(a) Turret clamp signal (TCLP)
[Classification]
Output signal
[Function] Directs the PMC to mechanically clamp the turret with a shot pin or the like. For the output
conditions and procedure, see the descriptions of the four procedures above.
(b) Turret clamp completion signal (TECLP)
[Classification]
Input signal
[Function] Notifies the control unit that the turret has been mechanically clamped with a shot pin or the
like. For the output conditions and procedure, see the descriptions of the four procedures
above.
(c) Turret unclamp signal (TUCLP)
[Classification]
Output signal
[Function] Directs the PMC to mechanically unclamp the turret with a shot pin or the like. For the output
conditions and procedure, see the descriptions of the four procedures above.
(d) Turret unclamp completion signal (TEUCL)
[Classification]
Input signal
[Function] Notifies the control unit that the turret has been mechanically unclamped. For the output
conditions and procedure, see the descriptions of the four procedures above.
(e) Turret rotation direction selection signals (TDIR1, TDIR2)
[Classification]
Input signals
[Function] Notify the control unit which direction to turn the turret when the turret is to be rotated in auto-
matic operation to select a specified tool number.
TDIR2
TDIR1 Turret axis moving direction.
LOW LOW Short cut
LOW HIGH
Forward direction (Turret turns counterclockwise)
HIGH LOW
Reverse direction (Turret turns clockwise)
HIGH HIGH Short cut
