Power supply mode and networking scheme

(1) Comparison of two power supply modes

table

Advantages and disadvantages of core components in power supply mode, applicable scenarios

Power Supply Unit (G396 series) provides energy feedback to the grid with low power consumption; Support reactive power compensation; The initial investment for stable DC voltage is high; Large space occupation, long-term operation, high regenerative energy scenario

High power AC-AC servo drive module with low cost; Small installation space; Simple wiring for regenerative energy dissipation through braking resistors; Oversized design is required for short-term operation and low regenerative energy scenarios

(2) Key requirements for networking

DC link coupling: Size 1-5 supports pre installed cables (20-193mm, 20mm ² copper bars), Size 6A-7 requires custom cables (35-95mm ²)

Maximum module quantity: A single Power Supply Unit can connect up to 6 DC-AC drive modules

Synchronization performance: Multi axis synchronization is achieved through EtherCAT bus, with synchronization error ≤ 1 μ s

Installation and environmental requirements

(1) Mechanical installation

Installation method: 35mm standard DIN rail vertical installation, backboard needs to be grounded (chrome/galvanized material is preferred)

Installation gap: The side spacing of the air-cooled module is ≥ 2mm, and the spacing of the Size 6A air-cooled module is ≥ 40mm; the liquid cooled module needs to reserve space for the coolant interface
