The figure below shows the compensation frequency when the inverter
output current is equal to the motor rated current.

• Motor Protection
J Motor overload detection J
The VS mini protects against motor overload with a built-in electronic
thermal overload relay.
• Electronic thermal reference current (n31 )
Set to the rated current value shown on the motor nameplate.
Note : Setting to O.OAdisables the motor overloadprotective function.
• Motor overload protection selection (n32)
Setlin_l Electronic Thermal Characteristics
O Applied to general-purpose motor, standard ratings
1 Applied to general-purpose motor, short-term ratings
2 Applied to inverter motor, standard ratings
3 Applied to inverter motor, short-term ratings
4 Electronic thermal overload protection not provided
The electronic thermal overload function monitors motor temperature,
based on inverter output ciarrent and time, to protect the motor from
overheating. When electronic thermal overload relay is enabled, an
"oL.' l" error occurs, shutting OFF the inverter output and preventing
excessive overheating in the motor. When operating with one inverter
connected to one motor, an external thermal relay is not needed. When
operating several motors with one inverter, instal! a thermal relay on each
motor.
