OM 1190-1 • MD4 VFD
CAUSE
Output current has exceeded trip
level .
Excessive intermediate circuit DC
voltage . DC overvoltage trip limit is
420 V for 200 V drives and 840 V
for 400 V drives .
Drive IGBT temperature is
excessive . Fault trip limit is 135 °C .
Short circuit in motor cable(s) or
motor
Intermediate circuit DC voltage is
not sufficient due to missing input
power line phase, blown fuse,
rectifier bridge internal fault or too
low input power .
Analog input AI1 signal has fallen
below limit defined by parameter
3021 AI1 FAULT LIMIT .
Analog input AI2 signal has fallen
below limit defined by parameter
3022 AI2 FAULT LIMIT .
Motor temperature is too high (or
appears to be too high) due to
excessive load, insufficient motor
power, inadequate cooling or
incorrect start-up data .
Measured motor temperature
has exceeded fault limit set by
parameter 3504 FAULT LIMIT .
Control panel selected as active
control location for drive has
ceased communicating .
Motor is operating in stall region
due to e .g . excessive load or
insufficient motor power.
External fault 1 Check external
devices for faults .
External fault 2 Check external
devices for faults .
Drive has detected earth (ground)
fault in motor or motor cable .

WHAT TO DO
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 .
Check that overvoltage controller is on (parameter 2505 OVERVOLT CTRL) .
Check input power line for static or transient overvoltage .
Check deceleration time (2203, 2206) .
Check ambient conditions . See also section Derating on page 103 .
Check air flow and fan operation.
Check motor power against unit power .
Check motor and motor cable .
Check that undervoltage controller is on (parameter 2006 UNDERVOLT CTRL) .
Check input power supply and fuses .
Check fault function parameter settings .
Check for proper analog control signal levels .
Check connections .
Check fault function parameter settings .
Check for proper analog control signal levels . Check connections .
Check motor ratings, load and cooling .
Check start-up data .
Check fault function parameters .
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 .
Check panel connection .
Check fault function parameters .
Check control panel connector. Refit 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
Check motor load and drive ratings .
Check fault function parameters .
Check parameter 3003 EXTERNAL FAULT 1 setting .
Check parameter 3004 EXTERNAL FAULT 2 setting .
Check motor .
Check fault function parameters .
Check motor cable . Motor cable length must not exceed maximum
specifications.
See section Motor connection data on page 104 .
