these
incidents. This section mainly describes the resolutions that the system is capable of
under the
emergency situation. Please see the relative explanation on these resolutions under the
emergency
by machine manufacturer.
2.4.1 Reset
Press key to resetTAC-1002T system when there are abnormal output and axis
operations:
1 All axes motion stops;
2 M, S function output is inactive (the parameter sets whether the system automatically
cuts off
signals of spindle rotation, lubricating, cooling by pressing key, defined by PLC
ladder);
3 Automatic run ends, modal function and state remain.
2.4.2 Emergency stop
During machine running, if the emergency button is pressed under the dangerous or
emergent
situation (external SP signal active), the CNC system enters into emergency status and
the machine
movement is stopped immediately. All the outputs such as the spindle running, cooling are
cut off. If
the emergency button is released, the emergency alarm is cancelled and the CNC resets.
Its circuit
wiring is shown in Section 2.3.1 of the Chapter.
Note 1: Ensure the fault is eliminated before the emergency alarm is cancelled.
Note 2: Pressing down the Emergency button prior to power on or off may alleviate the electric
shock to the
machine system.
Note 3: Re-perform the machine zero return to get the correct position coordinate after the
emergency alarm
is cancelled (machine zero return is forbidden if there is no machine zero on the machine.).
Note 4: Only Bit3 of the bit parameter No.172 is set to 0, is the external emergency stop active.
2.4.3 Feed hold
Press key during the machine running to make the running pause. However, in threading
cutting, tapping cycle state, the function cannot stop the running immediately.
2.4.4 Power-off
Under the dangerous or emergency situations during the machine running, the machine
power
