7.5 Error messages
Error message Cause Remedies
An01: AIN1_I < 4 mA Open-circuit monitoring for analog input 1
has tripped.
• Only if the analog input has been
configured as a current loop of
4 ... 20 (C00034/1 = 2).
• Check wiring of the analog X3/A1I
input terminal for open circuit.
• Check minimum current values of the
signal sources.
Ck16: Time overflow manual control Manual PC control: The connection
monitoring has tripped.
• The online connection between the PC
and the controller has been interrupted
for a longer period of time than the
timeout set in C00464/1.
• Check the communication link
between the PC and the controller.
• Check the voltage supply/function of
the controller.
• Adjust the timeout (C00464/1).
dF10: AutoTrip Reset Too frequent auto-trip reset. • Check the error cause that activates the
auto-trip reset.
• Eliminate error cause and reset
(acknowledge) error manually
afterwards.
dF14: SW/HW invalid Device error Consultation with Lenze required.
dF18: BU RCOM error
dF21: BU Watchdog
dF22: CU watchdog
dF25: CU RCOM error
Mains switching too frequent.
• Cyclic mains switching every 3 min is
permissible.
• After switching the mains 3 times in
one minute, there must be a switching
pause of 9 min.
• If the problem occurs again, you needs
to consult Lenze.
dF50: Retain error An error has occurred when accessing
retain data.
• Either caused by an internal hardware
error or by lack of mains switching after
a firmware download.
Mains switching
• If the problem occurs again, you needs
to consult Lenze.
dH09: EEPROM power section Device error Consultation with Lenze required.
dH10: Fan failure The device fan has failed.
Possible causes:
• The short-circuit check of the fan
connection has tripped.
• The speed monitoring of the fan has
tripped.
• Check the fan for short-circuit.
• Clean the fan.
dH68: Adjustment data error CU Device error Consultation with Lenze required.
dH69: Adjustment data error BU
FC1: Field controller limitation
The output of the field controller has
reached its maximum limit value. The
drive is at the torque limit in the field
weakening range.
• Observe load requirements.
• Correct dimensioning or reduce
setpoint from the field weakening
range if necessary.
FCH1: Switching frequency reduction Load-dependent switching frequency
reduction
• Observe load requirements.
• Correct dimensioning or reduce
setpoint generation dynamics if
necessary.
FCH2: Max. speed for Fchop Maximum speed for chopper frequency
has been reached.
• The maximum speed has been
exceeded depending on the switching
frequency.
Select the correct maximum speed as a
function of the switching frequency.
