Control card A001 develops the IGBT gate pulses. If the power supply part is OK, the
fuses are intact, the temperature watch PTCs are OK and correct set value info is received
from the potentiometer, then the gate pulses should be seen on connectors X10 and X11.
When the machine is idling, one must note that it is actually running intermittently.
