The Nordac Pro SK 500E series is the frequency inverter for all drive applications. It offers a wide power range, and its functionality can be extended with plug-in option modules. For heat removal this inverter uses variable cooling concepts that allow the heat to be dissipated outside the control cabinet. With a wide power range up to 160 kW and high quality torque regulation, the inverters can be operated where top performance and safety are required. The scalable functionality of our technology allows it to be used in many applications for the operation of both asynchronous and synchronous motors. Issues regarding installation and maintenance are quickly and easily resolved by the intuitive Nord CON tools and parameter structures.
- High precision regulation with current vector control
- 4-quadrant operation
- PLC function for functions close to the motor (PLC on Board)
- Energy-saving function for partial load operation
- Control and parameterisation tools and simple parameter structure
- Integrated line filter for compliance with EMC regulations
- Operation with synchronous and asynchronous motors
- Control and closed loop regulation
- POSICON – Integrated positioning mode and synchronisation
- STO and SS1 – Integrated functional safety
- Integrated brake rectifier for motor brake control
