Motor Protection - YASKAWA VS-606V7 Series Instruction Manual

• Motor Protection

Motor overload detection
The VS-606V7 protects against motor overload with a built-in electronic thermal
overload relay.
• Motor rated current (electronic thermal reference current, n036)
Set to the rated current value shown on the motor nameplate.
Note: Setting to 0.0A disables the motor overload protective function.
• Motor overload protection selection (n037, n038).

The electronic thermal overload function monitors motor temperature, based on
inverter output current and time, to protect the motor from overheating. When
electronic thermal overload relay is enabled, an "
inverter output and preventing excessive overheating in the motor. When operating
