Signal: ASIC-
DTR. If a caused
defect, the fault
might be on the
power board, in
the power mod-
ule, in the IGBT
or in the internal
cables. Some-
times short cir-
cuit fault
appears simulta-
neously with F7.
- If there is a brake
chopper in use, check
the isolation resistance
and resistance on the
brake resistor.
- FR4-FR8: measure the
power module directly
from its terminals.
Check the capasitors.
