Note
1. The drive of 75kW or below have internal brake units. The user only needs to configure external braking
resistor when the dynamic braking is required. The recommended resistor specification for 22kW drive is 3kW,
20Ω.
2. Please refer to Attached Table 2-2 when configuring the braking unit of 90kW or above.
4. Wring and use
1) Wiring of the built-in brake units of the drive
Please connect the brake resistor to the P/B1 and B2 terminals of drive main circuit.
2) External wiring diagram of external brake unit DBU-4030/4045
