How Do I Achieve A Motor Overload Protection In Accordance With Iec/Ul 61800-5-1 - Siemens SINAMICS G110M Operating Instructions Manual

8.25 How do I achieve a motor overload protection in accordance with
IEC/UL 61800-5-1?
Overview
The thermal motor model of the converter fulfills motor overload protection according to IEC/
UL 61800‑5‑1.
For motor overload protection according to IEC/UL 61800‑5‑1, some parameters of the thermal
motor model may also need to be adjusted.
Requirement
You have correctly entered the motor data during quick commissioning.
NOTICE
Thermal overload of third-party motors due to a trip threshold that is too high
With a Siemens motor, the converter sets the trip threshold of the thermal motor model to
match the motor. With a third-party motor, the converter cannot ensure in every case that the
trip threshold is exactly right for the motor. A trip threshold that is set too high can lead to a
thermal overload, thus causing damage to the motor.
• If required for a third-party motor, reduce the corresponding trip threshold p0605, p0615,
Procedure
1. Set p0610 = 12.
2. Set the following parameters depending on the motor:
– Induction motor:
– Synchronous motor
The trip threshold p0605, p0615 or p5391 parameterized in the motor data set may not be
increased.
Changing additional parameters of the thermal motor model can lead to the converter no longer
satisfying the motor overload protection in accordance with IEC/UL 61800‑5‑1.

or p5391.
p0612.1 = 1
p0612.9 = 1
For a motor without temperature sensor: p0625 = 40 °C
p0612.0 = 1
p0612.8 = 1
For a motor without temperature sensor: p0613 = 40 °C
