8.2.2 UL: Overload protection
The devices are equipped with a solid state motor overload protection and a solid state short circuit
protection.
The solid state motor overload protection protects the motor under overload conditions by reducing
current flow to the internal motor output terminals. This protection is achieved through algorithms
based on I
2
t of the current of the motor.
The overload protection circuitry is optimally configured to the specific motor and the specific final
application of the integrated variable speed drive. This is typically 100 % of the full-load current of the
motor.
The solid state short circuit protection acts to suspend current flow to the internal motor output
terminals upon sensing output current and DC-link voltage. The protection of the motor is comprised
of hardware and firmware.
8.2.3 UL: Short Circuit Current Rating
The devices are suitable for use in a circuit capable of delivering no more than 30/100 kA RMS
symmetrical (see also information sign on product). Details can be found in the following table.
The fusing for the short-circuit protection must comply with the requirements in UL248 and additional
to CAN/CSA C22.2 No. 248.
