• The braking energy must not exceed the energy dissipation capacity of the
selected resistor
• It is highly recommended that the resistor be protected from thermal overload;
see the section

Chopper data / Resistor selection table

The ratings apply at an ambient temperature of 40°C (104°F).

The internal chopper will withstand this continuous braking power. The braking is considered
continuous if the braking time exceeds 30 seconds.
Maximum braking power of the chopper. The chopper will withstand this braking power for 1
second within every 10 seconds. Note: The listed resistors will withstand this braking power
for 1 second within every 120 seconds.
The minimum allowed resistance of the braking resistor.
Resistance of the listed resistor.
Continuous power (heat) dissipation of the listed resistor when cooled naturally in a vertical
position.
