Warnings and Alarms
Instruction Manual High Power
ALARM 70, Illegal adjustable frequency drive configuration
The control card and power card are incompatible. Contact
your supplier with the type code of the unit from the
nameplate and the part numbers of the cards to check
compatibility.
ALARM 71, PTC 1 safe stop
Safe Stop has been activated from the PTC Thermistor
Card (motor too warm). Normal operation can be resumed
when the applies 24 V DC to T-37 again (when the motor
temperature reaches an acceptable level) and when the
Digital Input from the is deactivated. When that happens, a
reset signal must be is be sent (via Bus, Digital I/O, or by
pressing [Reset]). Note that if automatic restart is enabled,
the motor may start when the fault is cleared.
ALARM 72, Dangerous failure
Safe Stop with Trip Lock. Unexpected signal levels on safe
stop and digital input from the PTC thermistor card.
WARNING 73, Safe stop auto restart
Safe stopped. With automatic restart enabled, the motor
may start when the fault is cleared.
WARNING 76, Power unit set-up
The required number of power units does not match the
detected number of active power units.
Troubleshooting:
When replacing an F-frame module, this will occur if the
power specific data in the module power card does not
match the rest of the adjustable frequency drive. Please
confirm the spare part and its power card are the correct
part number.
77 WARNING, Reduced power mode
This warning indicates that the adjustable frequency drive
is operating in reduced power mode (i.e., less than the
allowed number of inverter sections). This warning will be
generated on power cycle when the adjustable frequency
drive is set to run with fewer inverters and will remain on.
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 initialized to default value
Parameter settings are initialized 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 par. err.
CSIV failed to init a parameter.
ALARM 85, Dang fail PB:
Profibus/Profisafe Error.

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 analog input terminal
54.
ALARM 243, Brake IGBT
This alarm is only for F Frame adjustable frequency drives.
It is equivalent to Alarm 27. The report value in the alarm
log indicates which power module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in F12 or F13 frame
sizes.
2 = right inverter module in F10 or F11 frame
sizes.
2 = second drive from the left inverter module in
F14 frame size.
3 = right inverter module in F12 or F13 frame
sizes.
3 = third drive from the left inverter module in
F14 frame size.
4 = far right inverter module in F14 frame size.
5 = rectifier module.
6 = right rectifier module in F14 frame size.
ALARM 244, Heatsink temperature
This alarm is only for F Frame adjustable frequency drives.
It is equivalent to Alarm 29. The report value in the alarm
log indicates which power module generated the alarm.
1 = left most inverter module.
2 = middle inverter module in F12 or F13 frame
sizes.
2 = right inverter module in F10 or F11 frame
sizes.
2 = second drive from the left inverter module in
F14 frame size.
3 = right inverter module in F12 or F13 frame
sizes.
3 = third drive from the left inverter module in
F14 frame size.
4 = far right inverter module in F14 frame size.
5 = rectifier module.
6 = right rectifier module in F14 frame size.
ALARM 245, Heatsink sensor
This alarm is only for F Frame adjustable frequency drives.
It is equivalent to Alarm 39. The report value in the alarm
log indicates which power module generated the alarm.
