Chapter 6 - Parameter Description [FU1]
6-19
FUN-57: No Motor Sel
FUN-58: No Motor Level
FUN-59: No Motor Time
These functions can be used to generate Trip in the
situation such that there is no actual inverter output
but the Main Controller of its hardware does not
recognize it. (Damage of SPS for Gate and Damage
of Gate, etc.)
When FU1-57 [No Motor Sel] is set to ‘Yes’, the
current below FU1-58 [No Motor Level] set value
flows, and FU1-59 [No Motor Time] set time is
passed, HW-Diag Trip is occurred and the message
‘No Motor Trip’ is displayed on the LCD for this trip.
(The current level is based on the set Motor rated
current.)
Trip occurs when the inverter is operated without
wiring a motor.

FU1-61: Electronic Thermal Level for 1 Minute
FU1-62: Electronic Thermal Level for Continuous
FU1-63: Electronic Thermal Characteristic (Motor
type) selection
These functions protect the motor from overheating
without using external thermal relay. Inverter
calculates the temperature rise in a motor based on
several parameters and determines whether or not the
motor is overheated from load current. Inverter will
turn off its output and display a trip message when
the electronic thermal feature is activated.
This function activates the ETH parameters by setting
‘Yes’. ETH level is set as the percentage of FU2-43
[Motor rated current].
This is the reference current when the inverter
determines the motor has overheated. For example, it
trips in one minute when 150% of rated motor current
in FU2-43 flows for one minute.
Note: The set value is the percentage of FU2-43
[Rated Motor Current].
This is the current at which the motor can run
continuously. Generally, this value is set to ‘100%’,
which means the motor rated current set in FU2-43.
This value must be set less than FU1-61 [ETH 1min].
Note: The set value is the percentage of FU2-43
[Rated Motor Current].
