Danfoss VLT 6000 HVAC Series User Manual

ALARM: 32
Motor phase W missing
(MISSING MOT.PHASE U):
Motor phase W between frequency converter and mo-
tor is missing.
Turn off the frequency converter and check motor
phase W.
WARNING/ALARM: 34
HPFB communication fault
(HPFB COMM. FAULT)
The serial communication on the communication op-
tion 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 cor-
rectly. Check the setting and select ‘Continue’ or
[STOP].
WARNING: 40
CHECK PAR. 103, 105
Parameter 103 Motor voltage, U
M,N
or 105 Motor cur-
rent, 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 car-
ried 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 Warn-
ing: 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 Warn-
ing: 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 maxi-
mum value and the auto derating function (par. 411) is
active. Warning: Temp. Auto derate.
