Cod.
Error
Description
03
Auxiliary voltage out of range
The auxiliary voltage (24VDC) is out of the permitted
range (<20.4V or >28V).
05
NTC motor interrupted
The temperature sensor of the motor is interrupted.
Make sure that the encoder cable is connected
properly.
06
Motor temperature too high
The motor temperature exceeds the limit set in the
parameter [1.4.10]. Make sure that the load applied to
the motor is correct (no obstructions, nor frictions). If
everything is OK or if you are testing the motor and it
has not reached the operating temperature yet, it is
recommended to increase the limit or to cool the
motor. If these hypotheses are all to be discarded, it is
recommended to replace the motor with one of a
larger size.
07
Driver temperature too high
The temperature inside the driver is too high. It is
recommended to increase the ventilation.
08
Intervention of protection
Irretrievable
. This error signals the intervention of
the hardware protection inside the power board. Here
are the main causes:
a) over-current in the output phases
b) simultaneous conduction of IGBT
c) power supply default on the IGBT Gates
d) disturb current impulse
There are several causes for these defects, both inside
and outside the driver: motor cable, motor turning-up,
wrong connections of the earth lines. If the error
persists, it will be necessary to replace the driver.
09
Maximum current overtaken
This error indicates that the current supplied to the
motor exceeds the maximum value permitted; this
value is calculated by choosing the lowest value among
the maximum current accepted by the motor and the
maximum current accepted by the driver.
10
DC BUS voltage exceeding the maximum
limit
This error occurs if the brake resistor can not absorb all
power generated by the motor. It can also indicate that
the mains voltage is higher than the limits permitted or
is considerably fluctuating.
13
Brake resistor temperature too high
The brake resistor temperature exceeds the pre-set
limits. The cause might be a too high voltage or an
excessive mass applied to the motor shaft.
14
DC BUS voltage too low
The mains voltage is not enough or one of the phases
of the main power supply is absent. It is recommended
to check the power supply line and the parameter
[1.7.2].
15
Corrupted data in EEPROM
Irretrievable
. This error occurs due to the EEPROM
memory damaged.
18
Current limit for time limit overtaken
See description of [1.3.9] in the menu VISIO 3000.
26
Ventilation not enough
At least one of the fans is running at insufficient speed.
Check if there are any obstructions that prevent the
fans from operating correctly.
27
Diagnostic problem
The inverter was disabled due to some problems in the
hardware diagnostic. If the problem persists, it is
recommended to replace the device.
