3.LASER SEQUENCE CONTROL LASER FUNCTION B-64663EN/01
- 52 -
The signal becomes 0 under the following conditions:
- When the discharge start signal (HVON) is set to 1 while the
discharge start ready signal (LRDY) is set to 1
- When the oscillator start signal (RUN) is set to 0 while the discharge
start ready signal (LRDY) is set to 1
- Discharge start signal
HVON<G222#7>
[Classification] Input signal
[Function] This signal starts discharge for the oscillator, thus readying the
oscillator for operation.
[Operation] When starting the oscillator
When the discharge start signal (HVON) is set to 1 while the
discharge start ready signal (LRDY) is set to 1, the CNC turns on
the laser power supply to achieve the reference discharge state
(simmer discharge for the Y series).
When stopping the oscillator
When the discharge start signal (HVON) is set to 0 while the
oscillator is operating, the CNC turns off the laser power supply
to stop discharge, and sets the discharge start ready signal
(LRDY) to 1.
- Reference discharge signal
RFHV<F221#5>
[Classification] Output signal
[Function] This signal notifies the PMC that discharge by the oscillator has been
started to achieve the reference discharge state (simmer discharge state
for the Y series).
[Output condition] The reference discharge signal becomes 1 under the following
condition:
- When the discharge start signal (HVON) is set to 1 while the
discharge start ready signal (LRDY) is set to 1
The reference discharge signal becomes 0 under the following
condition:
- When the RF power supply is turned on, reference discharge start
processing is performed, then calculation of the output compensation
coefficient is completed
- Oscillator signal
LSTR<F221#6>
[Classification] Output signal
[Function] This signal notifies the PMC that the oscillator is ready for output.
[Output condition] When the oscillator signal (LSTR) is set to 1, laser output can be
specified for machining.
The LSTR signal becomes "1" under the following condition.
- When the oscillator enters the reference discharge state (for the C
series) or the simmer discharge state (for the Y series)
The LSTR signal becomes "0" under the following conditions.
- When the discharge start signal (HVON) becomes 0.
- When the oscillator start signal (RUN) becomes 0.
- When a laser alarm occurs.
- When an emergency stop occurs.
