Fault Messages Generated by the Drive
Table 70: Fault Messages Generated by the Drive
CODE FAULT CAUSE WHAT TO DO
0001 OVERCURRENT (2310) 0305 bit 0
Output current has exceeded trip
level.
Check motor load.
Check acceleration time (2202 and 2505).
Check motor and motor cable (including phasing).
Check ambient conditions. Load capacity decreases if installation site ambient
temperature exceeds 40 °C.
See section Derating on page 350.
0002 DC OVERVOLT (3210) 0305 bit 1
Excessive intermediate circuit DC
voltage. DC overvoltage trip limit is
420 V for 200 V drives and 840 V
for 400 V drives.
Check that overvoltage controller is on (parameter 2505 OVERVOLT CTRL).
Check input power line for static or transient overvoltage.
Check deceleration time (2203, 2206).
0003
DEV OVERTEMP (4210)
0305 bit 2
Drive IGBT temperature is
excessive. Fault trip limit is 135 °C.
Check ambient conditions. See also section Derating on page 103.
Check air ow and fan operation.
Check motor power against unit power.
0004
SHORT CIRC (2340)
0305 bit 3
Short circuit in motor cable(s) or
motor
Check motor and motor cable.
0006
DC UNDERVOLT (3220)
0305 bit 5
Intermediate circuit DC voltage is
not sufcient due to missing input
power line phase, blown fuse,
rectier bridge internal fault or too
low input power.
Check that undervoltage controller is on (parameter 2006 UNDERVOLT CTRL).
Check input power supply and fuses.
0007
AI1 LOSS (8110) 0305 bit 6
(programmable fault function 3001,
3021)
Analog input AI1 signal has fallen
below limit dened by parameter
3021 AI1 FAULT LIMIT.
Check fault function parameter settings.
Check for proper analog control signal levels.
Check connections.
0008
AI2 LOSS (8110) 0305 bit 7
(programmable fault function 3001,
3022)
Analog input AI2 signal has fallen
below limit dened by parameter
3022 AI2 FAULT LIMIT.
Check fault function parameter settings.
Check for proper analog control signal levels. Check connections.
0009
MOT OVERTEMP (4310)
0305 bit 8 (programmable fault
function 0305…3009 / 3504)
Motor temperature is too high (or
appears to be too high) due to
excessive load, insufcient motor
power, inadequate cooling or
incorrect start-up data.
Check motor ratings, load and cooling.
Check start-up data.
Check fault function parameters.
Measured motor temperature
has exceeded fault limit set by
parameter 3504 FAULT LIMIT.
Check value of fault limit.
Check that actual number of sensors corresponds to value set by parameter
(3501 SENSOR TYPE).
Let motor cool down. Ensure proper motor cooling:
Check cooling fan, clean cooling surfaces, etc.
0010
PANEL LOSS (5300) 0305 bit 9
(programmable fault function 3002)
Control panel selected as active
control location for drive has
ceased communicating.
Check panel connection.
Check fault function parameters.
Check control panel connector. Ret control panel in mounting platform.
If drive is in external control mode (REM) and is set to accept start/stop,
direction commands or references via control panel:
Check Group 10: AcStart/Stop/Dir and Group 11: Reference Select settings.
0012
0012
MOTOR STALL (7121)
0305 bit 11 (programmable fault
function 3010…3012)
Motor is operating in stall region
due to e.g. excessive load or
insufcient motor power.
Check motor load and drive ratings.
Check fault function parameters.
0014
EXT FAULT 1 (9000) 0305 bit 13
(programmable fault function 3003)
External fault 1 Check external
devices for faults.
Check parameter 3003 EXTERNAL FAULT 1 setting.
0015
EXT FAULT 2 (9001) 0305 bit 14
(programmable fault function 3004)
External fault 2 Check external
devices for faults.
Check parameter 3004 EXTERNAL FAULT 2 setting.
0016
EARTH FAULT (2330) 0305 bit 15
(programmable fault function 3017)
Drive has detected earth (ground)
fault in motor or motor cable.
Check motor.
Check fault function parameters.
Check motor cable. Motor cable length must not exceed maximum
specications.
See section Motor connection data on page 104.
