GDM Info Description
PLL Unlocked The phase lock loop is not
locked to the input voltage.
This usually occurs when
the supply to the Rectifier
is switched off.
Control Model control loop
Model parameters out of range.
Unstable
Contactor Second contactor
Recharge activation before recharge
Error delay has timed out.
Bus Not Softcharge error if the DCV
Charging < 0.15 PU after 200 ms, bus
not charging.
FPGA Reset Either the FPGA (Field-
Programmable Gate Array):
- has not been reset, or
- did not initialize.
Bypass Error Errors indicated by bypass
manager.
Bypass Bypass SCRs enabled too
Contactor long before bypass
Forced contactor, detected in
hardware and contactor
forced closed.
SCR On Bypass SCRs on too long
Timeout when contactor remains
open (in AUTO BYPASS
mode).
SCR Not Off Bypass SCRs remain on too
Timeout long (not turned off) after
contactor opened from
STOP to RUN transition.
Bypass Open With bypass open the
Error current in inverter and
bypass CT are not the
same.
Bypass Close With bypass closed, the
Error inverter CT still carries
current.
