resistance, refer to Servo Drive Regenerative Energy Absorption Capacity on page 4-47.
Surface temperatures on regeneration resistors can reach 200°C.
Do not place objects that tend to catch fire near the resistors. To prevent
people from touching them, install a type of cover that enables heat
dissipation.
