Reason for trip
Solution
52
DO3 MDX-I/O
over ld
The DO3 output load current (MDX-I/O
option) is >200 mA
Check that DO3 is not short-circuited.
53
MDX-I/O link
Communication problem between the drive
and the MDX-I/O option
Check the MDX-I/O option mounting.
54
Not used
55 Unstable DC bus
The drive DC bus oscillates significantly
• Check the balancing of the mains phases.
• Check that all 3 mains phases are present.
56
IGBT V
Internal protection of phase V IGBTs
• Check the motor and cable insulation.
• Run power diagnostics.
57
IGBT W
Internal protection of phase W IGBTs
58
IGBT V
overheating
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 current levels depending on the frequency have been
complied with.
• Check that the switching frequency
05.18
is compatible
with the motor current level.
59
IGBT W
overheating
Overheating of phase W IGBTs
60
Diagnostic
Problem detected during the control and
interface boards test, the power test or
during the self-test
• Check that the STO1 and STO2 inputs are closed.
• See diagnostic error table.
63
STO input
inconsistency
The STO1 and STO2 inputs have had a
different state for more than 100 ms
Check the remote control link for the STO1 and STO2 inputs.
65
10V over ld
Overload on the +10 V power supply
Check the I/O wiring
66
DO1 over ld
The DO1 output load current
is >200 mA
Check that DO1 is not short-circuited.
67
Internal
ventilation
Not used
68
Motor
overcurrent
The current has exceeded the limit
programmed in
05.55
. The load is too high
for the setting.
Check that
05.55
is consistent with the application.
69
24 V MDX-I/O
over ld
The 24 V load current is too high
Check the MDX-I/O option I/O wiring.
70
4 mA loss on
MDX-IO AI4
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
4 mA loss on
MDX-IO AI5
Loss of the current reference on analog
input AI5 of the MDX-I/O option
101
AC mains loss
Loss of AC supply
• Check the input fuses
• Check the quality of the power supply (voltage dips)
102
Rectifier
Not used
