COSMOS DRIVER SERIES 3000 - USE AND MAINTENANCE MANUAL
10
DC bus voltage exceeding the maximum
limits
This error may occur if the braking resistor can not
absorb all power generated by the motor or is
interrupted. It can also indicate that the mains voltage
is higher than the limits permitted or is considerably
fluctuating.
If an external brake resistor is not available, make sure
there is a jumper to use the internal resistor.
11
Hall sensors code not correct
This error occurs if the motor encoder cable is not
connected or if the wiring is not correct. It can also
occur in case of break-down of the motor encoder or of
the hardware inside the driver.
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. It is recommended
to check the power supply line and the parameter
VnomDrv.
15
Corrupted data in EEPROM
Irretrievable
. It occurs due to EEPROM memory
damaged.
16
Too high speed
This error occurs when the parameter
VelmotMAX is
not properly installed or when a too high integrative
gain implies an excessive adjustment, which leads the
motor out of the limits permitted.
17
SW non longer under control
Irretrievable
. The microprocessor does not execute
the main programme.
18
Torque time limit overtaken
This error occurs when the time set in parameter
Tclim
is inferior to the time when the motor torque overtakes
the pre-set maximum torque value.
When the torque level exceeds the pre-set limit (*), a
timer is increased. When the torque returns below the
maximum level, the timer is decreased. If the timer
exceeds the pre-set value (**), an error is signalled.
This is a safety function available for the user, in order
to protect the application.
21
Motor voltage different from driver
voltage
The rated voltage set for the driver is different from
the motor voltage. This problem causes an excessive
power supply to the motor windings.
22
Excessive current for disabled driver
Irretrievable
. While the driver was disabled, the
sensors detected too high current. This problem is due
to the hardware malfunction.
23
SERCON chip hardware error
Irretrievable
. During the HW test on the SERCON
chip, some reading/writing errors occurred. The
specific error code is indicated in the SERCOS error list.
Make sure the SERCOS module has been
properly connected.
