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.
R Phase Voltage Low Fault (Vr Low Alarm)
Fault Definition:
Indicates that the R Phase Voltage connected to the terminal “25”, which is defined as “R”, 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.
S Phase Voltage Low Warning (Vs Low Warn)
Warning Definition:
Indicates that the S Phase Voltage connected to the terminal “24”, which is defined as “S”, is
lower than the value entered to the “
P144 Mains Voltage Low Warn
” parameter. It
is just a warning message. Does
not stop the motor.
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.
S Phase Voltage Low Fault (Vs Low Alarm)
Fault Definition:
Indicates t
hat the S Phase Voltage connected to the terminal “24”, which is defined as “S”, 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.
T Phase Voltage Low Warning (Vt Low Warn)
Warning Definition:
Indicates that the T Phase Voltage connected to the terminal “23”, which is defined as “T”, is
lower t
han the value entered to the “
P144 Mains Voltage Low Warn
” parameter. It is just a warning message. Does
not stop the motor.
