FAQs for System Design

What does a brake unit do?
It protects frequency inverters by switching excess braking energy from the motor to an external resistor, preventing DC bus overvoltage faults.

How do I select the right brake resistor?
Choose a resistor with a value not less than the "Min. Brake Resistance" (e.g., 18Ω) and a power rating matching your application's braking energy.

Which switching threshold should I use?
Set the threshold on the Lenze EMB9352-E just above your system's normal DC bus voltage to activate braking only when needed.

Can it handle frequent stopping cycles?
For frequent braking, size the external resistor based on the "Continuous Braking Power" rating and duty cycle, not just the peak power.

Where should it be installed in the cabinet?
Mount it near the drive(s) on a well-ventilated panel. The brake resistor must be installed outside the control cabinet due to heat.
