Troubleshooting
•
Select motor feedback function in
parameter 4-30 Motor Feedback Loss Function.
•
Adjust the tracking error band in
parameter 4-35 Tracking Error and
parameter 4-37 Tracking Error Ramping.
ALARM 79, Illegal power section configuration
The scaling card has an incorrect part number or is not
installed. The MK102 connector on the power card could
not be installed.
ALARM 80, Drive initialized
Parameter settings are initialized to default settings after a
manual reset. To clear the alarm, reset the unit.
ALARM 81, CSIV corrupt
6 6
CSIV file has syntax errors.
ALARM 82, CSIV parameter error
CSIV failed to initialize a parameter.
ALARM 83, Illegal option combination
The mounted options are incompatible.
ALARM 84, No safety option
The safety option was removed without applying a general
reset. Reconnect the safety option.
ALARM 88, Option detection
A change in the option layout is detected.
Parameter 14-89 Option Detection is set to [0] Frozen config-
uration and the option layout has been changed.
•
To apply the change, enable option layout
changes in parameter 14-89 Option Detection.
•
Alternatively, restore the correct option configu-
ration.
WARNING 89, Mechanical brake sliding
The hoist brake monitor detects a motor speed exceeding
10 RPM.
ALARM 90, Feedback monitor
Check the connection to encoder/resolver option and, if
necessary, replace VLT
Resolver Input MCB 103.
ALARM 91, Analog input 54 wrong settings
Set switch S202 in position OFF (voltage input) when a
KTY sensor is connected to analog input terminal 54.
ALARM 99, Locked rotor
The rotor is blocked.
WARNING/ALARM 101, Speed monitor
The motor speed monitor value is out of range. See
parameter 4-43 Motor Speed Monitor Function.
WARNING/ALARM 104, Mixing fan fault
The fan is not operating. The fan monitor checks that the
fan is spinning at power-up or whenever the mixing fan is
turned on. The mixing-fan fault can be configured as a
warning or an alarm trip in parameter 14-53 Fan Monitor.

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. Parameter 4-73 Position
Limit Function defines the function for this warning/alarm.
WARNING/ALARM 212, Homing not done
A homing function is selected in parameter 17-80 Homing
Function 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 parameter 17-85 Homing Timout.
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.
