Description
E24-Power
module
interference
Control board interference fault. Possible cause is incorrect converter installation or
a strong electromagnetic interference from surrounding devices. Test of this fault
can be turned off in service parameters.
E25-Interrupted AIN1
For the defined AIN Type 2 to 10 V (4 to 20mA) the AIN1 value dropped under the
1V or 2mA limit. Indicates the analog input interruption or a control board electronics
fault. For the duration of the fault, the value of AIN1 [256] (page 18) is displayed in
FAULTS window.
E26-Interrupted AIN2
For the defined AIN Type 2 to 10 V (4 to 20mA) the AIN2 value dropped under the
1V or. 2mA limit. Indicates the analog input interruption or a control board
electronics fault. For the duration of the fault, the value of AIN2 [280] (page 18) is
displayed in FAULTS window.
E27-Interrupted AIN3
For the defined AIN Type 2 to 10 V (4 to 20mA) the AIN3 value dropped under the
1V or 2mA limit. Indicates the analog input interruption or a control board electronics
fault. For the duration of the fault, the value of AIN3 [281] (page 18) is displayed in
FAULTS window.
E28-Interrupted AIN4
For the defined AIN Type 2 to 10 V (4 to 20mA) the AIN4 value dropped under the
1V or 2mA limit. Indicates the analog input interruption or a control board electronics
fault. For the duration of the fault, the value of AIN4 [282] (page 18) is displayed in
FAULTS window.
E29-Motor overload
Excessive thermal overload of the motor. High temperature of the motor evaluation
method is set by the parameter Motor overloading [27] (page 108). Actual status of
the motor temperature integral is in Thermal integral MT [33] (page 24). For the
duration of the fault, the value of Thermal integral MT [33] (page 24) is displayed in
FAULTS window.
E30-Current leak/Sum
I
Current leak in the motor cable or HW failure of the control board - current
measurement fault. It is recommended to measure leaks in the motor cable. It is
possible that the control board is impure by conductive impurities. Please, contact
VONSCH company. For the duration of the fault, the sum of phase currents is
displayed in FAULTS window.
E31-Too many faults
More faults occurred that specified by the parameter Max. fault count [431] (page
110) in a time period shorter than Min. fault period [432] (page 110). For the
duration of the fault, the value of number of faults is displayed in FAULTS window.
E32-IRC fault
IRC outage. Please, check the IRC cable first. IRC fault testing can be turned off in
Encoder fault mode [535] (page 109). For the duration of the fault, the value of
Freq. IRC1-IRC2 gear [1086] (page 19) is displayed in FAULTS window.
E33-Reserved
Reserved
E34-Reserved
Reserved
E35-Reserved
Reserved
E36-FLASH error
Data could not be written into the FLASH memory. The converter control board
might be damaged.
E37-Profibus Timeout
Profibus master does not communicate with the Profibus module, or the Profibus
module does not communicate with the converter for a defined period of time PB
Fault timeout [814] (page 116).
E38-ETP temperature
Temperature on the external temperature sensor ETP Temperature [869] (page 23)
exceeded the value defined by the parameter ETP Fault [866] (page 105). For the
duration of the fault, the value of ETP Temperature [869] (page 23) is displayed in
FAULTS window.
E39-Settings restored
Converter configuration was not valid (long or improper storage of the converter or
incorrect write to the RAM memory), so the parameters were restored from the
automatic backup. For the duration of the fault, the date of the last automatic setting
backup is displayed in FAULTS window.
E40-Blocked
converter.
Converter is blocked, or has invalid settings. If possible, use the restore point to
restore settings, otherwise call the VONSCH service.
E41-Pantograph
outage
Voltage drop or outage of the pantograph voltage of the trolley vehicle. For the
duration of the fault, the value of Pantograph voltage [113] (page 23) is displayed in
FAULTS window. For special converters only!
E42-Modbus Timeout
Modbus master does not communicate with the converter longer than defined period
of time MB Fault timeout [659] (page 113). For the duration of the fault, the value of
Slave count [801] (page 25) is displayed in FAULTS window.
