Communication fault between control card and BMC2.
ALARM 38: Internal fault number 1
Flash EEPROM fault on control card.
ALARM 39: Internal fault number 2
RAM fault on control card.
ALARM 40: Internal fault number 3
Calibration constant error in EEPROM.
ALARM 41: Internal fault number 4
Data values error in EEPROM.
ALARM 42: Internal fault number 5
Fault in motor parameter database.
ALARM 43: Internal fault number 6
General power card fault.
ALARM 44: Iinternal fault number 7

NOTE
When restarting after an alarm 38-45,
the VLT adjustable frequency drive will
display an alarm 37. In parameter 615 the
actual alarm code can be read.

ALARMS 50-56: AMT faults
ALARM 50: AMT not possible
One of the following three possibilities can occur:
- The calculated R value falls outside permitted limits.
S
- The motor current in at least one of the
motor phases is too low.
- The motor in use is too small for AMT
calculations to be performed.
ALARM 51: AMT Fault re. nameplate data
There is inconsistency in the registered motor data.
Check the motor data for the relevant setup.
ALARM 52: AMT faulty motor phase
The motor current in at least one of the motor
phases is too low.
ALARM 55: AMT timeout
The calculations are taking too long, possibly
due to noise in the motor cables.
ALARM 56: AMT warning during AMT
An adjustable frequency drive warning is given
while AMT is being performed.
WARNING 99: Locked
The control panel functions have been locked
via parameter 018.
