Troubleshooting
•
Cycle power to the frequency converter to
determine if the warning/alarm returns.
WARNING/ALARM 122, Mot. rotat. unexp.
The frequency converter performs a function that requires
the motor to be at standstill, for example DC hold for PM
motors.
WARNING 123, Motor Mod. Changed
The motor selected in
parameter 1-11 Motor Model
is not
correct. Check the motor model.
WARNING/ALARM 157, Power Limit Mot.
The output power exceeds the value defined in
parameter 4-82 Power Limit Motor Mode
.
WARNING/ALARM 158, Power Limit Gen.
The generating power exceeds the value defined in
parameter 4-83 Power Limit Generator Mode
.
WARNING 163, ATEX ETR cur.lim.warning
The frequency converter has run above the characteristic
curve for more than 50 s. The warning is activated at 83%
and deactivated at 65% of the allowed thermal overload.
ALARM 164, ATEX ETR cur.lim.alarm
Operating above the characteristic curve for more than
60 s within a period of 600 s activates the alarm, and the
frequency converter trips.
WARNING 165, ATEX ETR freq.lim.warning
The frequency converter is running for more than 50 s
below the allowed minimum frequency
(
parameter 1-98 ATEX ETR interpol. points freq.
).
ALARM 166, ATEX ETR freq.lim.alarm
The frequency converter has operated for more than 60 s
(in a period of 600 s) below the allowed minimum
frequency (
parameter 1-98 ATEX ETR interpol. points freq.
).
WARNING/ALARM 210, Position tracking
The actual position error exceeds the value in
parameter 4-71 Maximum Position Error
Parameter 4-70 Position Error Function
defines whether this
is a warning or an alarm.
WARNING/ALARM 211, Position limit
The position is outside the limits defined in
parameter 3-06 Minimum Position
and
parameter 3-07 Maximum Position
defines the function for this warning/alarm.
WARNING/ALARM 212, Homing not done
A homing function is selected in
and absolute positioning is executed before
homing is completed.
ALARM 213, Homing timeout
Homing was started but did not finish within the time
defined in
ALARM 214, No sensor input
A homing process with a homing function that requires a
sensor, or touch probe positioning is started with no input
defined for the sensor.
WARNING/ALARM 215, Start Fwd/Rev
One of the hardware end-limit options,
[12] Enable Start
Forward
or
[13] Enable Start Reverse
is active.
WARNING/ALARM 216, Touch Timeout
A touch probe sensor is not found within the time in
. The timeout timer is started
as soon as the touch probe positioning is activated even if
the application is not moving.
WARNING 220, Configuration file version not supported
The frequency converter does not support the current
configuration file version. Customization is aborted.
ALARM 246, Power card supply
This alarm is only for enclosure size F frequency converters.
It is equivalent to
alarm 46, Power card supply
.
The report value in the alarm log indicates which power
module generated the alarm:
1 = Inverter module to the far left.
2 = Middle inverter module in F2 or F4 frequency
converter.
2 = Right inverter module in F1 or F3 frequency
converter.
3 = Right inverter module in F2 or F4 frequency
converter.
5 = Rectifier module.
WARNING 249, Rect. low temperature
The temperature of the rectifier heat sink is lower than
expected.
Troubleshooting
•
Check the temperature sensor.
WARNING 250, New spare part
The power or switch mode supply has been exchanged.
Restore the drive type code in the EEPROM. Select the
correct type code in
parameter 14-23 Typecode Setting
according to the label on the drive. Remember to select
Save to EEPROM at the end.
WARNING 251, New typecode
The power card or other components are replaced, and the
type code has changed.
WARNING 253, Digital output X49/9 overload
Digital output X49/9 is overloaded.
WARNING 254, Digital output X49/11 overload
Digital output X49/11 is overloaded.
WARNING 255, Digital output X49/7 overload
Digital output X49/7 is overloaded.
ALARM 430, PWM Disabled
The PWM on the power card is disabled.
WARNING 128, Enc. Inc/Abs Res
Mismatch between incremental and absolute encoder
channels.
