4.13.1 Minimum resistances and power ratings for the braking resistor at 40 °C (104 °F)
Table 4-20 Braking resistor resistance and power rating (200 V)
Table 4-21 Braking resistor resistance and power rating (400 V)
* Resistor tolerance: ±10 %
Overload protection
When an external braking resistor is used, it is essential that an overload protection device is incorporated in the braking resistor circuit;
this is described in Figure 4-23 Typical protection circuit for a braking resistor on page 110.
