No. Reason for trip Possible cause and corrective actions
49 User trip 9 triggered by the serial link 10.38 = 49
-
50 User trip 10 triggered by the serial link
10.38
= 50
51 The DO2 output load current (MDX-I/O option) is > 200 mA Check that DO2 is not short-circuited
52 The DO3 output load current (MDX-I/O option) is > 200 mA Check that DO3 is not short-circuited
53
Communication problem between the drive and the
MDX-I/O option
Check the MDX-I/O option mounting
54 Communication problem between the drives -
56 Internal protection of phase V IGBTs
Check the motor and cable insulation
57 Internal protection of phase W IGBTs
58 Overheating of phase V IGBTs
• Clean the cabinet dust filters
• Check the drive ventilation units are working correctly
• Check that the product air inlet temperature is not outside
the limits
• If the trip appears at frequencies lower than 10 Hz, check
that the limit conditions given in section1.4.3 have been
complied with
59 Overheating of phase W IGBTs
60
A problem is detected during the control board and
interface test
Refer to parameters 17.05 , 17.08 and 17.09 in the
diagnostics menu in commissioning manual ref. 4617
63 The STO-1 and STO-2 inputs have had a different state for
more than 100 ms.
Check the remote control link for the STO-1 and STO-2
inputs
65 Overload on the +10 V power supply Check the I/O wiring
66 The DO1 output load current is > 200 mA Check that DO1 is not short-circuited
67 The internal ventilation is not working (50T and 100T only) Get in touch with your usual LEROY-SOMER contact
68
The current has exceeded the limit programmed in 05.55 .
The load is too high for the setting
-
69 The 24V load current is too high Check the MDX-I/O option I/O wiring
70 Loss of the current reference on analog input AI4 of the
MDX-I/O option
Check the input wiring and source of the MDX-I/O option
71
Loss of the current reference on analog input AI5 of the
MDX-I/O option
Check the input wiring and source of the MDX-I/O option
101 Mains loss
• Check the input fuses
• Check the quality of the power supply (voltage dips)
102 Loss of rectifier synchronisation with the mains
Check the quality of the power supply (commutation
notches)
