No. Reason for trip Possible cause and corrective actions
14
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
16
18 A stop command has been given during the autotune
phase
Repeat the autotune procedure (see 05.12 )
20 Motor thermal overload
• Make sure that the motor duty cycle does not exceed its
thermal capacity
• Check the setting of
04.15
"Thermal time constant" with
respect to the application
21 Overheating of the 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 limit conditions given in section 1.4.3 have been
complied with
24 Opening of the DI1/CTP input of the PX1 drive terminal
block or T1/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 on the +24V or digital output power supply Check the I/O wiring
28 Loss of the current reference on analog input AI2
Check the input wiring ans source
29 Loss of the current reference on analog input AI3
30 Loss of communication on the P2 connector serial link
• Check the cable connections
• Check the parameter
11.63
is compatible with the timing
of requests from the master
31
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 Problem during measurement of the stator resistance Check the motor wiring
34 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 Simultaneous opening of both STO (Safe Torque Off)
inputs during operation
Check the remote control link
37 Encoder break
• Check the encoder wiring
• Check the encoder connections
38
Breakdown of synchronous motor in sensorless closed
loop mode
Check the menu 5 parameters are compatible with the
values on the motor nameplate
39 The rectifier connot synchronise with the mains supply
Check the quality of the power supply (commutation
notches)
40 Loss of exchanges between the control board and the
MDX-ENCODER module
Check that the MDX-ENCODER module is properly
attached
