5.4.2 Power-Up
After the power supply has been connected, the control system powers up. The
HMI Embedded/HMI Advanced system software is installed on the PCU when
the system is delivered, but it can also be installed via a PCMCIA card.
Note
The use of modules via L2-DP and certain CP modules means that the power
up time is longer than a standard configuration.
To bring the control system into a defined initial state, initialization (NCK general
reset) is required when the power is first connected. To do this, turn the start-up
switch S3 on the NCU/CCU to position “1” and switch the control on. The control
then powers up, the SRAM memory is erased and the machine data are preset
to the default values.
Table 5-1 For the significance of the NCK start-up switch S3 (see Fig. 5-1)
Setting Meaning
0 Normal mode: Power-up with the set data.
1 Start-up MODE: The data in the buffered RAM (SRAM) is cleared and the
default machine data is loaded.
2–7 Reserved
Once the NCK has powered up correctly, the number “6” appears on the NCU
status display. The LEDs “+5V” and “SF” (SINUMERIK READY) light up.
Now switch NC start-up switch S3 back to the “0” position.
During power-up, the various power-up phases appear on the status display
(7-segment display) on the NCU module.
