ALARM 79, Illegal power section configuration
The scaling card is the incorrect part number or not installed.
Also MK102 connector on the power card could not be
installed.
ALARM 80, Drive initialised to default value
Parameter settings are initialised to default settings after a
manual reset. Reset the unit to clear the alarm.
ALARM 81, CSIV corrupt
CSIV file has syntax errors.
ALARM 82, CSIV parameter error
CSIV failed to init a parameter.
ALARM 83, Illegal option combination
The mounted options are not supported to work together.
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 has been detected. This alarm
occurs when
14-89 Option Detection
is set to [0]
Frozen config-
uration
and the option layout for some reason has changed.
An option layout change has to be enabled in
14-89 Option
Detection
before the change is accepted. If the change of
configuration is not accepted, it is only possible to reset
Alarm 88 (Trip-lock) when the option configuration has been
re-established/corrected.
WARNING 89, Mechanical brake sliding
The hoist brake monitor has detected a motor speed >
10rpm.
ALARM 90, Feedback monitor
Check the connection to encoder/ resolver option and
eventually replace the MCB 102 or MCB 103.
ALARM 91, Analogue input 54 wrong settings
Switch S202 has to be set in position OFF (voltage input)
when a KTY sensor is connected to analogue input terminal
54.
ALARM 92, No flow
A no-flow condition has been detected in the system.
22-23 No-Flow Function
is set for alarm. Troubleshoot the
system and reset the frequency converter after the fault has
been cleared.
ALARM 93, Dry pump
A no-flow condition in the system with the frequency
converter operating at high speed may indicate a dry pump.
22-26 Dry Pump Function
is set for alarm. Troubleshoot the
system and reset the frequency converter after the fault has
been cleared.
ALARM 94, End of curve
Feedback is lower than the set point. This may indicate
leakage in the system.
22-50 End of Curve Function
is set for
alarm. Troubleshoot the system and reset the frequency
converter after the fault has been cleared.
ALARM 95, Broken belt
Torque is below the torque level set for no load, indicating a
broken belt.
22-60 Broken Belt Function
is set for alarm.
Troubleshoot the system and reset the frequency converter
after the fault has been cleared.
ALARM 96, Start delayed
Motor start has been delayed due to short-cycle protection.
22-76 Interval between Starts
is enabled. Troubleshoot the
system and reset the frequency converter after the fault has
been cleared.
WARNING 97, Stop delayed
Stopping the motor has been delayed due to short cycle
protection.
22-76 Interval between Starts
is enabled.
Troubleshoot the system and reset the frequency converter
after the fault has been cleared.
WARNING 98, Clock fault
Time is not set or the RTC clock has failed. Reset the clock in
0-70 Date and Time
.
WARNING 163, ATEX ETR cur.lim.warning
The warning limit of ATEX ETR rated current curve has been
reached. The warning is activated at 83% and de-activated at
65% of the permitted thermal overload.
ALARM 164, ATEX ETR cur.lim.alarm
The ATEX ETR permitted thermal overload has been
exceeded.
WARNING 165, ATEX ETR freq.lim.warning
The frequency converter is running more than 50 seconds
below the permitted minimum frequency (
1-98 ATEX ETR
interpol. points freq.
[0]).
ALARM 166, ATEX ETR freq.lim.alarm
The frequency converter has operated more than 60 second
(in a period of 600 seconds) below the permitted minimum
frequency (
1-98 ATEX ETR interpol. points freq.
[0]).
ALARM 243, Brake IGBT
This alarm is only for F Frame drives. It is equivalent to Alarm
27. The report value in the alarm log indicates which power
module generated the alarm:
ALARM 244, Heatsink temperature
This alarm is only for F Frame frequency converters. It is
equivalent to Alarm 29. The report value in the alarm log
indicates which power module generated the alarm:
ALARM 245, Heatsink sensor
This alarm is only for F Frame frequency converters. It is
equivalent to Alarm 39. The report value in the alarm log
indicates which power module generated the alarm
1 = left most inverter module.
2 = middle inverter module in F2 or F4 frequency
converter.
2 = right inverter module in F1 or F3 frequency
convertere.
3 = right inverter module in F2 or F4 frequency
converter.
