This manual includes safety, commissioning of the supply section with ISU, functional description, parameters, fault tracing, and technical data for ACA 635 IGBT Supply Sections and ACS 800-17 Line-side Converter.
This manual covers the ACA 635 IGBT Supply Sections used with the ACS 600 MultiDrive, including safety guidelines, installation, commissioning, and maintenance procedures. It is intended for qualified electricians and service personnel working on the drive and supply units.
The document is organized into chapters on safety instructions, operation basics, hardware description, parameters, fault tracing, and technical data, with appendices containing rating tables and circuit diagrams. Detailed specifications for analogue and digital I/O, relay outputs, and transformer requirements are also provided.
| Analogue input resolution | 0.025 % (12 bit) |
|---|---|
| Digital input logical thresholds | < 8 VDC “0”, > 12 VDC “1” |
| Relay output switching capacity | 8 A at 24 VDC or 250 VAC |
| Rated apparent supply power | 260 kVA to 4728 kVA |
Power must be switched off, wait at least 5 minutes, verify that the voltage between UDC+ / UDC‑ and the frame is near 0 V, and open all switch fuses before any installation or maintenance work.
The analogue inputs are galvanically isolated as a group, with an isolation test voltage of 500 VAC for 1 minute.
A transformer dedicated to drives and motors, or one with two secondary windings where one is dedicated to drives and motors, must be used.
