Installation Manual –Page 19 / 20
8: Motor overtemp.
The temperature measured by the PTC thermistor on the motor exeed the allowed value.
Shut off the system, wait 1 minute, then try to restart the system. If the error does not go eway,
contact the closest Climma service center.
9: Drive Failure
10: Cpu error
There has been a data loss in inverter memory, contact the closest Climma service center.
11: Param. default
12: DC bus ripple
Check the power supply as there are maybe fluctuations.
Shut off the system, wait 1 minute, then try to restart the system. If the error does not go eway,
contact the closest Climma service center.
13: Data comms fault
Data connection from the board to the inverter was interrupted. Try to reset manually the alarm,
then if it does not go away, shut off the system, wait 1 minute, then try to restart the system. If
the error does not go away, contact the closest Climma service center.
14: Drive thermistor
There has been an internal fault of the inverter, please contact the closest Climma service center.
15: Autotune fault
16: Drive disabled
Cables are disconnected, an external protector maybe has been activated; check the
connections.
Try to reset manually the alarm, then if it does not go away, shut off the system, wait 1 minute,
then try to restart the system. If the error does not go away, contact the closest Climma service
center.
17: Motor phase
Motor cable disconnected, check the cables from the inverter drive to the compressor with
power supply off.
Try to reset manually the alarm, then if it does not go away, shut off the system, wait 1 minute,
then try to restart the system. If the error does not go away, contact the closest Climma service
center.
18: Fan fault
Fan failure, try to reset manually the alarm, then if it does not go away, shut off the system, wait
1 minute, then try to restart the system. If the error does not go eway, contact the closest
Climma service center.
19: Speed fault
Incorrect parameters or unsuitable motor load. Try to reset manually the alarm, then if it does
not go away, shut off the system, wait 1 minute, then try to restart the system. If the error does
not go eway, contact the closest Climma service center.
20: PFC Failure
PFC circuit overcurrent; there may be a problem in the power supply or maybe other circuit
errors, so check also for other errors, then shut off the system, wait 1 minute, then try to restart
the system and reset the alarm. If the error does not go eway, contact the closest Climma service
center.
21: Error code 21
AC input voltage too high, Check line voltage and the presence of inductive loads on the line that
may generate
overvoltage.
22: PFC Undervoltage
AC input voltage too low, Check line voltage and the power cables.
23: STO Survey
internal fault. Try to reset manually the alarm, then if it does not go away, shut off the system,
wait 1 minute, then try to restart the system. If the error does not go eway, contact the closest
Climma service center.
24: STO Survey
25: Ground fault
Drive earth leakage current is too high. Check motor earth insulation and the connection
cables.
26: Internal error 1
CPU overload. Try to reset manually the alarm, then if it does not go away, shut off the system,
wait 1 minute, then try to restart the system. If the error does not go eway, contact the closest
Climma service center.
27: Internal error 2
Data loss in memory. Try to reset manually the alarm, then if it does not go away, shut off the
system, wait 1 minute, then try to restart the system. If the error does not go eway, contact the
closest Climma service center.
28: Drive overload
The current delivered has exceeded the drive’s rated current beyond the maximum time
allowed, check the load, motor sizing and the cables.
30: Error code 30
98 : Unexpected inverter restart
99: Unexpected inverter stop
There is a problem in the data connection between inverter and board. This may be due to a
problem in the power supply that allowed for a communication problem between inverter and
board. Try to reset manually the alarm, then if it does not go away, shut off the system, wait 1
minute, then try to restart the system. If the error does not go eway, contact the closest Climma
service center.
