Parameter-
setting
interface name
Reason for trip Solution
31 EEPROM fail.
Number of write cycles to EEPROM
exceeded (>1,000,000)
• Change the control board
• Check the recurrence of write cycles from the drive
controller
33 Stator resistance Trip during measurement of the
stator resistance
• Check the motor wiring
34 Fieldbus loss Disconnection of the fieldbus during
operation or timing error
• Check the fieldbus connections
• Check that parameter 15.07 is compatible with the timing
of requests from the master
35 STO inputs
Simultaneous opening of both STO (Safe
Torque Off) inputs during operation
Check the remote control link
37 Encoder break One of the encoder feedback data items is
missing
• Check the encoder wiring
• Check the encoder connections
38 Breakdown
Breakdown of synchronous motor in
sensorless closed loop mode
Check the menu 5 parameters are compatible with the values
on the motor nameplate
39 Mains synchro
The rectifier cannot synchronise with the
mains supply
(
POWERDRIVE FX
only)
Check the quality of the power supply (commutation notches
present)

51
DO2 MDX-IO
over ld
The DO2 output load current (MDX-IO
option) is >200 mA
Check that DO2 is not short-circuited
52
DO3 MDX-IO
over ld
The DO3 output load current (MDX-IO
option) is >200 mA
Check that DO2 is not short-circuited
53 MDX-IO link
Communication problem between the
drive and the MDX-IO option
Check the MDX-IO option mounting
54
Internal
serial link
Communication problem between the
drives
Check the setting of 11.66
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
• If
POWERDRIVE MD2:
run power diagnostics
57 IGBT W Internal protection of phase W IGBTs
58
Th
IGBT V
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
