Troubleshooting
WARNING 64, Voltage limit
The load and speed combination demands a motor
voltage higher than the actual DC link voltage.
WARNING/ALARM/TRIP 65, Control card over
temperature
Control card over temperature: The cutout tempera-
ture of the control card is 80° C.
WARNING 66, Heatsink temperature low
This warning is based on the temperature sensor in
the IGBT module.
Troubleshooting:
ALARM 67, Option module configuration has
changed
One or more options have either been added or re-
moved since the last power-down.
ALARM 68, Safe stop activated
Safe stop has been activated. To resume normal op-
eration, apply 24 Vdc to terminal 37, then send a reset
signal (via Bus, Digital I/O, or by pressing the reset
key. See par. .
ALARM 69, Power card temperature
The temperature sensor on the power card is either
too hot or too cold.
Troubleshooting:
Check the operation of the door fans.
Check that the filters for the door fans are not
blocked.
Check that the gland plate is properly installed on
IP 21 and IP 54 (NEMA 1 and NEMA 12) drives.
ALARM 70, Illegal FC Configuration
Actual combination of control board and power
board is illegal.
ALARM 72, Dangerous failure
Safe stop with trip lock. Unexpected signal levels on
safe stop.
Warning 76, Power Unit Setup
The required number of power units does not match
the detected number of active power units.
Troubleshooting:
Warning 73, Safe stop auto restart
Safe stopped. Note that with automatic restart ena-
bled, the motor may start when the fault is cleared.
WARNING 77, Reduced power mode:
This warning indicates that the drive is operating in
reduced power mode (i.e. less than the allowed num-
ber of inverter sections). This warning will be gener-
ated on power cycle when the drive is set to run with
fewer inverters and will remain on.

ALARM 79, Illegal power section configuration
The scaling card is the incorrect t number or not in-
stalled. 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.
ALARM 91, Analog input 54 wrong settings
Switch S202 has to be set in position OFF (voltage
input) when a KTY sensor is connected to analog in-
put terminal 54.
ALARM 92, No flow
A no-load situation has been detected in the system.
See parameter group 22-2.
ALARM 93, Dry pump
A no-flow situation and high speed indicates that the
pump has run dry. See parameter group 22-2.
ALARM 94, End of curve
Feedback stays lower than the set point which may
indicate leakage in the pipe system.
ALARM 95, Broken belt
Torque is below the torque level set for no load, in-
dicating a broken belt. See parameter group 22-6.
ALARM 96, Start delayed
Motor start has been delayed due to short-cycle pro-
tection active. See parameter group 22-7.
WARNING 97, Stop delayed
Stopping the motor has been delayed due to short
cycle protection is active. See parameter group 22-7.
WARNING 98, Clock fault
Clock Fault. Time is not set or RTC clock (if mounted)
has failed. See parameter group 0-7.
WARNING 201, Fire M was Active
Fire Mode has been active.
WARNING 202, Fire M Limits Exceeded
Fire Mode has suppressed one or more warranty
voiding alarms.
WARNING 203, Missing Motor
A multi-motor under-load situation was detected, this
could be due to e.g. a missing motor.
WARNING 204, Locked Rotor
A multi-motor overload situation was detected, this
could be due to e.g. a locked rotor.
