Mains filter
Mains filters are used to comply with the EMC requirements for variable speed drive systems. The requirements are defined in the product standard EN 61800-3. The standard differentiates the requirements according to the installation site:
- First environment
- Residential buildings and sites where the control cabinet is connected directly, without a transformer, to the public low-voltage network.
- Second environment
- Industrial areas connected to the medium voltage network via a transformer.
The required category is then derived from this:
- Category C2
- Stationary drive systems for operation in the first and second environments.
- Category C3
- Drive systems for operation in the second environment.
The power supply modules of the AX8000 servo system are designed with integrated mains filters for compliance with category C3. Optional mains filters are available for use in the first environment. In addition, a mains choke must be used. The following dependencies on the total motor cable length must be observed:
Power supply module | Category C3 | Max. total motor cable length |
|---|---|---|
AX8620 1-phase | Integrated mains filter | up to 300 m without mains choke up to 500 m with optional mains choke AX2090-ND80-00xx |
AX8620 3-phase | Integrated mains filter | |
AX8640 | Integrated mains filter | |
AX8525 and AX8540 | Integrated mains filter |
Power supply module | Category C2 | Max. total motor cable length |
|---|---|---|
AX8620 1-phase | with mains filter | up to 300 m |
AX8620 3-phase | with mains filter | up to 500 m |
AX8640 | with mains filter | |
AX8525 and AX8540 | with mains filter |
