No.
Description
55 W Offset in current measuring
circuit (I_wr) too large in self-
test
56 W Offset in current measuring
circuit (I_wr_neg) too large in
self-test
57 W Actual speed of motor too
high
58 E BLDC motor does not start.
The inverter attempts to start
the motor depending on
P51-
t_start
; after 3 unsuccessful
start attempts or after 15 se-
conds, the start procedure is
terminated.
60 E Communication of the control
panel to the motor control bro-
ken
61 E Automatic test on switching
on, program memory
62 E Automatic test on switching
on, data memory of control
circuit board
63 W Error while loading a parame-
ter from the EEPROM data
memory
64 W Error while loading a calibration
value from the EEPROM data
memory
65 E No program in flash memory
of motor control circuit board
66 E Software versions of control
circuit board and of motor
control circuit board do not
correspond
67 W Watchdog reset on control cir-
cuit board
Cause
Electronics for measuring the inter-
mediate circuit voltage are faulty
Electronics for measuring the inter-
mediate circuit voltage are faulty
Actual motor speed is 10% above
the nominal speed. Motor cannot
follow the nominal speed, motor
driven externally.
Motor blocked or incorrect start
parameters.
Hardware or software interruption of
communication
Flash memory on control circuit
board faulty
EEPROM on control circuit board
faulty
Loss of data, EEPROM on control
circuit board faulty
Loss of data, EEPROM on control
circuit board faulty
Loss of data, flash on motor control
circuit board faulty
Internal communication of control
circuit board to motor control circuit
board broken since protocols do not
match one another.
Strong EMC interference on control
circuit board
Rectification
If the error persists in spite of re-
peated resetting, a hardware error
is present and the inverter should
be sent for repair.
If the error persists in spite of re-
peated resetting, a hardware error
is present and the inverter should
be sent for repair.
Decrease nominal speed more
slowly or increase power of brake
resistance.
Check motor, check parameters
P51 ... P54.
If the error persists in spite of re-
peatedly switching on and off or
resetting, a hardware error is present
and the inverter should be sent for
repair.
If the error persists in spite of re-
peatedly switching on and off or
resetting, a hardware error is present
and the inverter should be sent for
repair
If the error persists in spite of re-
peatedly switching on and off or re-
setting, a hardware error is present
and the inverter should be sent for
repair
Input the corresponding parameters
again; if the error occurs repeatedly,
the inverter should be sent for re-
pair.
The inverter is still ready for operation
in the uncalibrated state; if the error
persists in spite of repeated resetting,
the inverter should be sent for repair.
Send inverter for repair or request
the flash programming software
from KaVo.

Warning display is automatically
reset after 10 seconds, motor
continues to run.
