S Phase Voltage High Warning (Vs High Warn)
Warning Definition: Indicates that the S Phase Voltage connected to the terminal “24”, which is defined as “S”, is
higher than the value entered to the “P146 Mains Voltage High Warn” parameter. It is just a warning message. Does
not stop the motor.
Possible Causes and required actions: There may be a voltage rise in the system. The value that is entered to the
parameter may have been wrong for the application.
S Phase Voltage High Fault (Vs High Alarm)
Fault Definition: Indicates that the S Phase Voltage connected to the terminal “24”, which is defined as “S”, is higher
than the value entered to the “P145 Mains Voltage High Alarm” parameter. It is a malfunction that stops the
compressor rapidly.
Possible Causes and required actions: There may be a voltage rise in the system. The value that is entered to the
parameter may have been wrong for the application.
T Phase Voltage High Warning (Vt High Warn)
Warning Definition: Indicates that the T Phase Voltage connected to the terminal “23”, which is defined as “T”, is
higher than the value entered to the “P146 Mains Voltage High Warn” parameter. It is just a warning message. Does
not stop the motor.
Possible Causes and required actions: There may be a voltage rise in the system. The value that is entered to the
parameter may have been wrong for the application.
T Phase Voltage High Fault (Vt High Alarm)
Fault Definition: Indicates that the T Phase Voltage connected to the terminal “23”, which is defined as “T”, is higher
than the value entered to the “P145 Mains Voltage High Alarm” parameter. It is a malfunction that stops the
compressor rapidly.
Possible Causes and required actions: There may be a voltage rise in the system. The value that is entered to the
parameter may have been wrong for the application.
R Phase Voltage Low Warning (Vr Low Warn)
Warning 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 “P144 Mains Voltage Low Warn” parameter. It is just a warning message. Does
not stop the motor.
