Parameter
Type/Unit Description
6 = Reserved
5 = IPM FAULT: Indicates the inverter power stage
Integrated Power Module (6 IGBT switches) is faulty.
4 = UNDERT: Indicates an excessively low
temperature or a temperature sensor failure
condition (Bit set if the instantaneous state of
UNDERT_MON signal is low.) [May be reset via
TRIP_RESET if the hardware trip source has cleared]
3 = OVERT: Indicates an OVER-TEMPERATURE
condition (Bit set if the instantaneous state of
OVERT_MON signal is low.) [May be reset via
TRIP_RESET if the hardware trip source has cleared]
2 = OVERI: Indicates an OVER-CURRENT condition
(Bit set if the instantaneous state of OVERI_MON
signal is low.) [May be reset via TRIP_RESET if the
hardware trip source has cleared]
1 = OVERV: Indicates an OVER-VOLTAGE condition.
(Bit set if the instantaneous state of OVERV_MON
signal is low.) [May be reset via TRIP_RESET if the
hardware trip source has cleared]
0(LSB) = OVERF: Indicates an OVER-SPEED
condition. (Bit set if the instantaneous state of
OVERF_MON signal is low.) [May be reset via
TRIP_RESET if the hardware trip source has cleared]
0x0066 Diagnostic
Register 01
Bit eld 15(MSB)= Reserved
14 = INRUSH_THERMISTOR_ NOT_BYPASSED
Inrush circuit has over-heated due to repeated power
cycling so the drive cannot start, or pre-charge relay
open for some other reason. The self-test warning
will be set, possibly following a delay. The self-test
fault bit will be set if this condition prevents the drive
from running. Power should be removed and the
drive left to cool down for 5 minutes before re-
applying the power. Note that the raw state of the
pre-charge relay output is set in the Digital Output
Register at 0x1CA1. Non-resettable after fault
indicated.
13 = WATCHDOG TIMEOUT
Power on self-test warning – generates fault log and
then automatically clears the fault and restarts. Self-
resetting fault
12= Reserved
11= EEPROM_LOW_VCC_ WRITE_DISABLE
Resettable Warning. EEPROM write access blocked
because internal 15 V rail voltage is below the
threshold.
