User Manual R0.2
Possible Causes and required actions:
There may be a voltage drop in the system. The value that is entered to the
parameter may have been wrong for the application. If the mains voltage is not connected to the device, the
parameter "P153 Mains Failure Control" should be set to "0". If the connection is made, make sure that the "P151
Mains Connection Type" parameter is set correctly.
T Phase Voltage Low Fault (Vt Low Alarm)
Fault Definition:
Indicates that the T Phase Voltage connected to the terminal “23”, which is defined as “T”, is lower
than the value entered to the
“P14
3 Mains Voltage Low Alarm
”
parameter. It is a malfunction that stops the
compressor rapidly.
Possible Causes and required actions:
There may be a voltage drop in the system. The value that is entered to the
parameter may have been wrong for the application. If the mains voltage is not connected to the device, the
parameter "P153 Mains Failure Control" should be set to "0". If the connection is made, make sure that the "P151
Mains Connection Type" parameter is set correctly.
High Frequency Warning (Freq High Warn)
Warning Definition:
Indicates that the 3 Phase Frequency connected to the terminals “25
-24-
23”, which are defi
ned
as “R
-S-
T” is higher than the value entered to the “P150
Mains Frequency High Warn
” parameter. It is just a warning
message. Does not stop the motor.
Possible Causes and required actions:
There may be an increase in the frequency of mains voltage. The value that is
entered to the parameter may have been wrong for the application.
High Frequency Fault (Freq High Alarm)
Fault Definition:
Indicates that the 3 Phase Frequency connected to the terminals “25
-24-
23”, which are defined as
“R
-S-
T” is higher than the value entered to the “P149
Mains Frequency High Alarm
” parameter. It is a malfunction
that stops the compressor rapidly.
Possible Causes and required actions:
There may be an increase in the frequency of mains voltage. The value that is
entered to the parameter may have been wrong for the application.
Low Frequency Warning (Freq Low Warn)
Warning Definition:
Indicates that the 3 Phase Frequency connected to
the terminals “25
-24-
23”, which are defined
as “R
-S-
T” is lower than the value entered to the “P148 Mains Frequency Low Warning” parameter. It is just a
warning message. Does not stop the motor.
Possible Causes and required actions:
There may be a decrease in the frequency of mains voltage. The value that is
entered to the parameter may have been wrong for the application.
