New Modular System from NORD: Full Compatibility with Decentralized Drive Electronics

[Cengiz Özemli]

NORD DRIVESYSTEMS is introducing a new modular system that includes decentralized drive electronics and efficient motors. This system offers design flexibility because the NORDAC LINK and NORDAC ON frequency inverters share the same communication and safety functions.

### Flexibility and Compatibility in System Design
Large internal logistics operations for e-commerce providers, parcel distribution centers, and airports benefit from space-saving decentralized drive solutions. However, if frequency inverters mounted on walls or motors have different safety and communication features, additional installation is required. NORD's new modular system solves this problem with decentralized drive electronics for consistent use.

### Technical Specifications

• Motor types: IE3 asynchronous and IE5+ synchronous motors
• Frequency inverters: NORDAC ON (0.37-3.7 kW, wall and motor mounting) and NORDAC LINK (0.37-7.5 kW, wall mounting)
• Common communication protocols: PROFINET, EtherCAT
• Safety standards: SIL3 / PLe and SIL2 / PLd levels via PROFIsafe and FSoE
• Safety functions: STO, SS1-t, SS1-r, SLS, SMS, SSM (no encoder required)
• Ethernet connection and integrated safe inputs/outputs

### Performance and Safety
The frequency inverters enable encoderless control of highly efficient IE5+ synchronous motors. The CFC open-loop injection method allows starting with 150% overload and provides rapid accelerations. This method offers high energy efficiency, especially at partial loads, and reduces material and installation costs.

### Ease of Installation and Maintenance
The modular system allows users to easily choose between motor-mounted and wall-mounted frequency inverters. Integrated functions simplify installation and maintenance processes by reducing cabling work. This enables the creation of less complex system architectures with expanded performance.
