Heatsink overheating
detected by thermal
sensor
(> 100°C for 16T and
22T,
> 95°C for other
ratings)
•Cooling fan (for
those fitted with one)
•Ambient temperature
• Check that:
-the fans are rotating
-the cooling intakes
are not obstructed
-the ambient temperature
is less than 50°C
-the space around the
drive is sufficient
• Reduce the switching

Tripping of the motor
thermal sensor
•Terminal 13 • Check the motor load
• Reduce the level of
overload
• Check the motor
ventilation and the
ambient temperature
• Check the sensor wiring
26 O.Ld1
Overload on
the +24V power supply
or logic output
•Terminal 7: +24V
•Terminal 4: 0V
• Check the load circuit
of the +24V, and also
the logic output
CAUTION:
When the checks have
been completed, this
fault can only be
cleared by pressing
.
28 cL
Loss of the current
reference on A2
analogue input
(terminal 5)
•4-20mA or 20-4mA

• Check that the current
reference is > 3mA

Serial link problem
• Check the connection
of the serial link.
31 EEF EEPROM fault
•Control card • Switch off and then
on again
• If the fault persists,
consult LEROY-SOMER
32 PH Phase loss
•Power supply
terminals L1, L2, L3
• Check the mains
supply (this fault
does not exist on the
M/TL versions).
33 rS
Fault during
measurement of the
stator resistance
•Concordance
of the motor power
with the drive power
•Motor connection
• Adapt the drive power
to the motor power
• Check the motor
