Additional details: Brake resistor for inverters ATV930U15M3-U22M3, ATV930U55N4-U75N4, ATV950U55N4-U75N4, ATV950U55N4E-U75N4E. Reference values for a light braking cycle. Power VA 0.16 kW, protection class IP20, resistance 60 Ohm at 20 °C. Supply voltage 200-240 V or 380-480 V 50/60 Hz.

Load factor for resistors: The value of the average power that can be dissipated from the resistor into the housing at 50 °C. Determined for a load factor during braking, which corresponds to the majority of common applications.

Standard overload: 0.8 s braking at a braking torque of 1.2 Tn for a cycle of 40 s.
High overload: 0.8 s braking at a braking torque of 1.5 Tn for a cycle of 40 s.
Required number per inverter: 1.

Brake resistors allow Altivar process frequency inverters to operate during braking until standstill by dissipating the braking energy. They enable a maximum transient braking torque. Brake resistors are designed for a defined cycle. Depending on your own applications and cycles, you can use these resistors or define a new value.

Brake resistors for light braking cycles for machines with cycles and mass inertia. The braking power is limited to 1.5 Tn for 0.8 s every 40 s. Brake resistors for medium braking cycles for machines with high mass inertia and conveyor systems. The braking power is limited to 1.35 Tn for 4 s every 40 s.
