P-22 DOOR INTERLOCK FUNCTION
<Restrictions on operations>
1.
With the machine door opened, it is possible to carry out such operations as shaping soft
jaws and measuring the tool offset data by rotating the spindle and indexing the turret head
in the manual mode (handle, jog, rapid traverse, zero return).
1.
Since the rapid traverse rate of the axis which has the fastest rapid traverse rate is
clamped at 5 m/min, the clamp feedrate of other axes may be lower than 5 m/min.
2.
When moving an axis after releasing the door interlock function, if the DOOR
INTERLOCK key-switch is placed in the
NORMAL
position while the axis is moved
at a rate faster than 500 mm/min, the door interlock function becomes valid and the
axis is stopped. In this case, excessive servo error alarm may occur.
This alarm does not occur when the DOOR INTERLOCK key-switch is placed in the
NORMAL
position after axis movement is stopped by releasing the axis feed switch.
2.
With the machine door opened, it is possible to check the program or carry out test cutting in
the memory (tape) mode by making the single block function valid.
If automatic operation is executed with the machine door open and the single block
function set valid, rapid traverse rate is clamped at 5 m/min. For cutting feedrate, no such
restriction applies.
3.
With the machine door opened, it is possible to execute the MDI mode operation.
<Precautions on automatic operation>
If the single block function is made invalid during automatic operation under the following
conditions, the machine is placed in the feed hold mode and the error message is
displayed (EX2029 CYCLE START PERMISSION IMPERFECT).
The machine door is open.
The DOOR INTERLOCK key-switch is placed in the
RELEASE
position.
The single block function is valid.
The machine can restart by pressing the automatic operation (cycle start) after making the
single block function valid.
