Fault messages

Fault message indication
Display Cause Description
E01 Overcurrent in the output stage in
static operation
If the output current reaches an excessive level, the output voltage is switched off. This happens
when
• the frequency inverter’s output is short-circuited,
• the motor is blocked,
• an excessive load is suddenly applied to the output.
E02
Overcurrent in the output stage
during deceleration
E03
Overcurrent in the output stage
during acceleration
E04
Overcurrent in the output stage at
standstill
E05
Overload The internal electronic motor protection has switched off the output voltage because the motor was
overloaded.
E06
Overload If the duty factor of the built-in braking transistor of the DF6 is too great, the braking transistor is
switched off (the generated overvoltage disconnects the output voltage).
E07
Overvoltage The output voltage has been switched off because the motor was operating regeneratively.
E08
EEPROM fault If the program memory does not operate reliably due to radio frequency interference or excessive
temperature, the output voltage is switched off.
If the supply voltage is switched off while the RST input is active, an EEPROM fault occurs when the
supply voltage is reapplied.
E09
Undervoltage If the DC voltage is too low, the output voltage is switched off (fault-free function of electronics no
longer possible; any problems, such as overheating of motor and insufficient torque).
E10
Fault in current transformer The output voltage is disconnected when a fault occurs in the built-in current transformer of the DF6.
E11
Processor malfunction The processor does not operate correctly. The output voltage is switched off.
E12
External fault message The output voltage is switched off due to an external fault message which is present on a digital
input configured as an EXT input.
E13
Restart inhibit activated The mains voltage was switched on or an intermittent interruption in the supply voltage has occurred
while unattended start protection (input USP) was active.
E14
Earth fault Earth faults between the U, V or W terminals and earth are being reliably detected. A protective
circuit prevents destruction of the frequency inverter, but does not protect the operating personnel.
E15
Mains overvoltage If the supply voltage is higher than permitted, the output voltage is switched off 100 seconds after
the voltage supply has been switched on.
E16
Intermittent mains failure An intermittent mains failure of at least 15 ms has occurred. This message appears when the
duration of the mains failure is longer than the time entered under PNU b002 (a page 134)
E21
Overtemperature If the temperature sensor installed in the power section records an operating temperature above the
permissible limit value, the output voltage is switched off.
E23
Gate array fault Internal communication error between CPU and gate array
E24
Mains phase failure One of the three mains phases has failed.
E30
IGBT fault If an excessive current is applied at an IGBT (transistor in the power end stage), the output voltage
is switched off to protect the transistor.
E35
Thermistor fault signal If the resistance of the external PTC thermistor connected to the PTC input (terminals TH and CM1)
is too high, the output voltage is switched off.
----
Undervoltage Because the input voltage is too low, the frequency inverter attempts a restart. If the restart fails, a
fault message is triggered to save the undervoltage fault and the frequency inverter switches off.
E60 to
E69
Fault, expansion module 1 A fault has occurred in expansion modules 1 or 2 and their connections. For further information, refer
to the manuals for the affected expansion module.
