Protecting the motor and motor cable in short circuits
The drive protects the motor cable and motor in a short-circuit situation when:
• the motor cable is sized correctly
• the motor cable type complies with the motor cable selection guidelines by ABB
• the cable length does not exceed the allowed maximum length specified for the
drive
• the setting of parameter 99.10 Motor nominal power is equal to the value on the
motor rating plate.
The electronic power output short-circuit protection circuitry meets the
requirements of IEC 60364-4-41 2005/AMD1, Clause 411.
