Reason for trip
Solution
This trip cannot be reset for a period of 10 seconds.
5 I IMBALANCED
Motor current imbalance:
vectorial sum of the 3 motor
currents is not zero
• Check the motor insulation
• Check the cable insulation
6
Loss of a
motor phase Loss of a motor phase
Check the motor cable and resistance values between
motor phases
7
Overspeed
The speed is higher than (1.3 x
01.06
) or
(
01.06
+ 1000 rpm)
• Check the drive settings
• When the flying restart function is not being used, check that
06.09
is at «Disabled»
8
Drive overload
Ixt
The drive overload level exceeds the
conditions defined in section 1.4.2 of the
installation manual
• Check the drive is suitable for the motor current cycle
• Check the ambient temperature
9
IGBT U
Internal protection of phase U IGBTs
• Check the motor and cable insulation
POWERDRIVE MD2 only:
• Run power diagnostics
10
Th rectifier
Rectifier heatsink temperature too high
• Clean the cabinet dust filters
• Check the drive external and internal fans are
working correctly
• Check that the product air inlet temperature is not outside
the limits
11
Encoder rot
The measured position does not vary
(only if the MDX-ENCODER option
is present)
• Check the encoder wiring
• Check that the motor shaft turns
13
UVW invert
The encoder U, V, W signals are reversed
(only if encoder option is present)
Check the conformity of the encoder wiring
14 TUNE U Encod During the autotune phase, one of the
encoder U, V or W commutation channels
is not present
• Check the encoder wiring
• Check the encoder connections
• Change the encoder
15 TUNE V Encod
16 TUNE W Encod
18
Autotune
A stop command has been given during
the autotune phase.
Repeat the autotune procedure (see
05.12
)
19
Brak. resist.
Parameter
10.39
«Braking energy
overload accumulator» has reached
100%
• Check the settings of
10.30
and
10.31
• Check the resistor is compatible with the application
requirements
21
Th
IGBT U
Overheating of phase U 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
24
Motor PTC
Opening of the PTC input of the PX1
terminal block or T1 and T2 inputs of the
MDX-ENCODER option
• Check the ambient temperature around the motor
Check that the motor current is less than the stated current
• Check the thermal sensor wiring
26
Overload
+ 24V
Overload on the +24 V power supply or
digital outputs
Check the I/O wiring
28
AI2 loss
Loss of the current reference on
analog input AI2
Check the input wiring and source
29
AI3 loss
Loss of the current reference on
analog input AI3
30
COM loss
Loss of communication on the P2
connector serial link
• Check the cable connections
• Check that parameter
11.63
is compatible with the timing
of requests from the master
