1
The brake resistor should be able to endure 10 times the overload capacity.
*
2
The brake resistor should be able to endure 3.3 times the overload capacity.

If you choose other brake resistors instead of Deltas, calculate the maximum power and average power of t he
selected braking power to ensure that they meet the requirements. Maximum power: Vb

The calculation of the brake resistor value and braking power is based on Delta’s brake resistor.
