Braking resistor, for ATV930D18M3 - D22M3, ATV930D75N4 - D90N4, ATV950D75N4 - D90N4, ATV950D75N4E - D90N4E drives. Reference values for a light braking cycle. Power VA 1.9 kW, protection class IP23, resistance 5 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 that 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 drive 1. Braking resistors allow Altivar Process drives to operate during braking to a standstill by dissipating the braking energy. They enable maximum transient braking torque. Braking resistors are designed for a defined cycle. Depending on your own applications and cycles, you can use these resistors or define a new value. Braking resistors for light braking cycles for machines with cycles and inertia. The braking power is limited to 1.5Tn for 0.8s every 40s. Braking resistors for medium braking cycles for machines with high inertia and conveyor systems. The braking power is limited to 1.35Tn for 4s every 40s.
