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,
insufficient 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.
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: Start/Stop/Dir and
Group 11: Reference select settings.
0012 MOTOR STALL
(7121)
0305 bit 11
(programmable fault
function
3010…3012)
Motor is operating in
stall region due to eg
excessive load or
insufficient 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 a
ground fault in motor
or motor cable.
Check motor.
Check fault function parameters.
Check motor cable. Motor cable length
must not exceed maximum
specifications. See section Motor
connection data on page 395.
