WARNING/ALARM: 34
HPFB communication fault
(HPFB COMM. FAULT)
The serial communication on the communication
option card is not working.
ALARM: 37
Inverter fault (GATE DRIVE FAULT):
IGBT or the power card is defective. Contact
your Danfoss supplier.
Auto-optimisation warnings 39-42
Automatic motor adaptation has stopped, since
some parameters have probably been set wrongly,
or the motor used in too big/small for AMA to be
carried out. A choice must thus be made by pressing
[CHANGE DATA] and choosing ‘Continue
’
+ [OK] or
‘Stop
’
+ [OK]. If parameters need to be changed,
select ‘Stop
’
; start up AMA all over.
WARNING: 39
CHECK PAR. 104, 106
Parameters 104
Motor frequency f
M,N
, or 106
Rated
motor speed n
M,N
, have probably not been set correctly.
Check the setting and select ‘Continue
’
or [STOP].
WARNING: 40
CHECK PAR. 103, 105
Parameter 103
Motor voltage, U
M,N
or 105
Motor
current, I
M,N
has not been set correctly. Correct
the setting and restart AMA.
WARNING: 41
MOTOR TOO BIG (MOTOR TOO BIG)
The motor used is probably too big for AMA to be
carried out. The setting in parameter 102
Motor
power, P
M,N
may not match the motor. Check the
motor and choose ‘Continue
’
or [STOP].
WARNING: 42
MOTOR TOO SMALL (MOTOR TOO SMALL)
The motor used is probably too small for AMA to
be carried out. The setting in parameter 102
Motor
power, P
M,N
may not match the motor. Check the
motor and select ‘Continue
’
or [STOP].
ALARM: 60
Safety stop (EXTERNAL FAULT)
Terminal 27 (parameter 304 Digital inputs) has been
programmed for a
Safety interlock
[3] and is a logic ‘0
’
.
WARNING: 61
Output frequency low (FOUT < FLOW)
The output frequency is lower than parameter 223
Warning: Low frequency, f
LOW
.
WARNING: 62
Output frequency high (FOUT > FHIGH)
The output frequency is higher than parameter
224
Warning: High frequency, f
HIGH
.
WARNING/ALARM: 63
Output current low (I MOTOR < I LOW)
The output current is lower than parameter 221
Warning: Low current, I
LOW
. Select the required
function in parameter 409
Function in case of no load
.
WARNING: 64
Output current high (I MOTOR > I HIGH)
The output current is higher than parameter 222
Warning: High current, I
HIGH
.
WARNING: 65
Feedback low (FEEDBACK < FDB LOW)
The resulting feedback value is lower than parameter
227
Warning: Low feedback, FB
LOW
.
WARNING: 66
Feedback high (FEEDBACK > FDB HIGH)
The resulting feedback value is higher than parameter
228
Warning: High feedback, FB
HIGH
.
WARNING: 67
Remote reference low (REF. < REF LOW)
The remote reference is lower than parameter 225
Warning: Low reference, RE
FLOW
.
WARNING: 68
Remote reference high (REF. > REF HIGH)
The remote reference is higher than parameter 226
Warning: High reference, REF
HIGH
.
WARNING: 69
Temperature auto derate (TEMP.AUTO DERATE)
The heat sink temperature has exceeded the maximum
value and the auto derating function (par. 411) is
active.
Warning: Temp. Auto derate.
WARNING: 99
