The external 24V DC power supply must meet the following requirements: maximum voltage ≤ 30VDC, maximum current ≤ 8A

Braking system: For elevator applications, rapid braking response requirements, and in CFC/SERVO mode, both the AC and DC sides of the brake must be simultaneously disconnected

General technical requirements (common to 5 series)

Key wiring configuration

Classification of Core Wiring Diagrams

Key rules for wiring type coverage content

Power supply section+brake L1/L2/L3 connection, PE grounding, brake AC/DC side cut-off. The brake rectifier needs to be independently powered, and motor voltage supply is prohibited

DC link connection between MDR series and inverter DC link anti reverse connection to avoid equipment damage

When the brake resistors (BW series) BW…, BW… – T (built-in temperature switch), BW… – P (auxiliary contact) trigger protection, the K11 contactor needs to be disconnected without interrupting the resistance circuit

Key points for wiring safety

Size 1/2/2S models: The power terminal (X1) and motor terminal (X2) do not have PE interfaces and require the use of PE terminals next to the DC link (X4)

Brake connector: Strictly follow the wiring sequence, incorrect connections can cause irreversible damage to the brake

Wiring of brake rectifier: When installing in the control cabinet, the connecting wire should be separated from other power cables and only allowed to follow the same path as the shielded power cable
