When the regenerative energy exceeds the capacity of the built-in regenerative resistor, you
should use an external regenerative resistor. Pay special attention to the following when using a
regenerative resistor:
1.
Choose the correct resistance value (P1.052) and capacity (P1.053) for the regenerative
resistor; otherwise it might affect the performance.
2.
When using an external regenerative resistor, ensure the total resistance value is greater
than the minimum allowable resistance value of the servo drive. For general applications,
you can connect more than one resistor in series. If the value (from resistors connected in
series) exceeds the rated range, you can reduce the value by connecting the resistors in
parallel. If you want to connect the resistors in parallel to increase the power of the
regenerative resistors, make sure the resistance value meets the requirements.
See the following diagram and settings for connecting the regenerative resistors in series
and parallel.

Normally, if the capacity of the regenerative resistor (the average value) is within the rated
capacity, the temperature can increase to 120°C (248°F) or even higher (under the condition
that the regenerative energy continues to function). For safety reasons, apply forced cooling
to reduce the temperature of the regenerative resistor. Alternatively, you can use
regenerative resistors equipped with thermal switches. Contact the manufacturer for the load
characteristics of the regenerative resistor.
