Description
NEW FIRMWARE DOWNLOADED
This marks the point when the controller has just received new
code. When new firmware is downloaded, older events may not be
interpreted correctly in this listing. Always save the Event Log to a
text file before downloading new firmware.
Real Date marker ofReal Time marker of These mark the point when a date marker or a time marker were
inserted. It shows the date in year/month/day format, and the time
in hours:minutes:seconds format.
Inverter Fault ON
Inverter Fault OFF
These events mark when an inverter fault occurred that affects the
inverter’s power switches. Over large motor phase currents or high
temperatures can endanger the power switches.
Forced open loop ON
Forced open loop OFF
These events mark when the controller has had to go into forced
open loop because of sensor measurement problems.
Over mechanical danger speed
Under mechanical danger speed
Over speed occurred
Over speed problem OFF
These events mark when speed problems have occurred.
Over Inverter Voltage ON
Over Inverter Voltage OFF
Over battery voltage
Under battery voltage
These events mark when bus voltage problems occurred. Over
inverter voltage means the inverter had to enter forced voltage
control.
Untrustworthy voltage measurement
occurred
The bus voltage measurement is suspect and the inverter shut
down.
Sensor voltage invalid
Sensor voltage good
These events mark when the voltage that powers the controller’s
sensors is not at an acceptable level and subsequently when the
voltage has become good again.
CTFault safety ON
This event marks when a problem was detected with the current
sensors of the controller.
Leg sums not zero
Over Leg Current
Leg significantly over current
Leg dangerously over current
Leg Current Separation ONCE
These events mark errors on the motor’s phase legs.
Over Inverter Temperature ON
Over Inverter Temperature OFF
Over Stator Temperature ON
Over Stator Temperature OFF
Over Rotor Temperature ON
Over Rotor Temperature OFF
These events mark when the temperatures reached unacceptable
levels, and when they subsequently reached an acceptable level.
