Danfoss FC 302 VLT Automation Drive

Danfoss VLT AutomationDrive FC 302 series drive is flexible, modular and adaptable

A VLT® AutomationDrive is built on a flexible, modular design to provide an extraordinarily versatile motor control solution. The drive is equipped with a wide range of industry features that enable optimal process control, higher quality output and reduce costs related to spare parts and service.

Free to equip.
The VLT® AutomationDrive can optimally control nearly all standard industrial motor technologies, including Asynchronous, IPM, SPM, Synchronous Reluctance and PM assisted Synchronous Reluctance motors. This means that system designers, OEMs and end users are free to connect the drive to their selected motor and remain confident that the system will perform to the highest possible standards. As an independent manufacturer of AC drive solutions, you can count on Danfoss to support all commonly used motor types and foster ongoing development as new technologies emerge.

Speaks your language.
When it comes to working with advanced technologies, such as AC drives, it is fairly easy to feel lost while navigating through hundreds of parameters. Using a graphical interface makes this process much easier; especially when it lists parameters in your native language. As many as 28 language options are available, including several Cyrillic, Arabic (right to left) and Asian options. Additionally, the ability to save up to 50 user-selectable parameters further simplifies interactions with key parameter settings for your unique application.

690 V.
The 690 V versions of VLT® AutomationDrive FC302 units for the power range from 1.1 kW up to 1400 kW can control motors down to 0.37 kW without stepdown transformer. This enables you to choose from a broad variety of compact, reliable and efficient drives for demanding production facilities operating from 690 V mains networks.

Reduce costs with compact drives.
A compact design and efficient heat management enable the drives to take up less space in control rooms and panels, thereby reducing initial costs. Compact dimensions are also an advantage in applications where drive space is restricted, making it possible for designers to develop smaller applications without being forced to compromise on protection and grid quality. For example, VLT® .
AutomationDrive FC302 in a D or E enclosure size is 25-68% smaller than equivalent drives. Despite the compact dimensions, all units are nevertheless equipped with integrated DC link chokes and EMC filters, which help to reduce grid pollution and reduce cost and efforts for external EMC components and wiring. The IP20 version is optimized for side-by-side mounting in cabinets to 50 °C without derating and features covered power terminals to prevent accidental contact. The AC drive can also be ordered with an optional brake chopper in the same package size. Control and power cables are fed in separately at the bottom. The AC drives combine a flexible system architecture that allows them to be adapted to specific applications, with a uniform user interface across all power classes. This allows you to adapt the drive to the exact needs of your specific application. As a result, project work and costs are subsequently reduced. The easy-to-use interface reduces training requirements. The integrated SmartStart guides users quickly and efficiently through the setup process, resulting in fewer faults due to configuration and parameterization errors.

Danfoss FC 302 series integrated motion controller – for positioning and synchronization applications.

Perform high-precision positioning and synchronization, simply using an AC drive. With the Integrated Motion Controller (IMC) functionality, the VLT® AutomationDrive FC 302 replaces more complex positioning and synchronization controllers, to save time and cost. Positioning and synchronization operations are typically performed using a servo drive or a motion controller. However, many of these applications do not actually require the dynamic performance available from a servo drive. Therefore the FC 302 with IMC is a costeffective, high-performance alternative to servo in single-axis positioning and synchronizing applications. Use IMC for many applications that have been solved with servo drives until now, such as:
- Rotary tables
- Cutting machines
- Packaging machines

Use FC 302 to run an induction or PM motor with or without motor feedback – with no need for additional hardware. With sensorless control (no motor feedback) best performance is achieved with a PM motor. The performance of sensorless control of induction motors is however sufficient for less-demanding applications.

With IMC you save time and cost:
- No advanced programming and fewer components means fewer hours needed for engineering, installation and commissioning
- Save further cost for a feedback device, cabling and installation by using sensorless control
- To save cost for a home sensor and cabling, use the “homing on torque limit” function

The IMC solution provides easy and safe set-up:
- Configuration via parameters, with no advanced programming required. Reduced complexity will minimize the risk of errors
- To add more functionality, use the Smart Logic Controller (SLC), which is fully compatible with IMC
- To realign the home position during operation, use the “home synchronizing” function

Positioning.
In positioning mode, the drive controls movement over a specific distance (relative positioning) or to a specific target (absolute positioning). The drive calculates the motion profile based on target position, speed reference and ramp settings.

There are 3 positioning types using different references for defining the target position:
- Absolute positioning.
Target position is relative to the defined zero point of the machine.
- Relative positioning.
Target position is relative to the actual position of the machine. - Touch probe positioning.
Target position is relative to a signal on a digital input.

Synchronizing.
In synchronizing mode, the drive follows the position of a master; multiple drives can follow the same master. The master signal can be an external signal, for example, from an encoder, a virtual master signal generated by a drive or master positions transferred by fieldbus. Gear ratio and position offset is adjustable by parameter.

Homing.
With sensorless control and closed loop control with an incremental encoder, homing is required to create a reference for the physical position of the machine after power up. There are several home functions with and without sensor to choose from. The home synchronizing function can be used to continuously realign the home position during operation when there is some sort of slip in the system. For example in case of sensorless control with an induction motor or in case of slip in the mechanical transmission.

Danfoss VFD FC 302 series tailored safety.

- VLT® Safety Option MCB150 and MCB 151.
The MCB150 and MCB 151 can be integrated directly in the AC drive and is prepared for future connection to common safety bus systems. The module is certified according to ISO 13849-1 up to PLd as well as IEC61508/ IEC62061 up to SIL 2 and provides SS1 and SLS (SMS) functionality. The option can be used in low and high demand applications. SS1 offers ramp and time based functionality. SLS can be configured both with and without ramp down on activation. When MCB 151 is combined with the built-in VLT® Sensorless Safety MCB 159 option, an external sensor is no longer required for safe speed monitoring.

- VLT® Safety Option MCB152.
The VLT® Safety Option MCB 152 operates the safety functions of an AC drive via the PROFIsafe fieldbus in combination with the VLT® PROFINET MCA 120 fieldbus option. Central and decentral drives located at different machinery cells can easily be interconnected with the PROFIsafe safety fieldbus. This interconnection enables activation of Safe Torque Off (STO) irrespective of where a hazard occurs. The safety functions of the MCB 152 are implemented according to EN IEC61800-5-2. The MCB 152 supports PROFIsafe functionality to activate integrated safety functions of the VLT® AutomationDrive from any PROFIsafe host, up to Safety Integrity Level SIL 2 according to EN IEC 61508 and EN IEC 62061, Performance Level PL d, Category 3 according to EN ISO 13849-1.

- Quick commissioning.
Parameter configuration is fully integrated into the VLT® Motion Control Tool MCT 10 and enables simple start-up and easy maintenance. Visual instructions in MCT 10 ensure both fault-free wiring and that safety parameters are correctly transferred from the PC to the drive. The software also offers easy diagnosis and a dynamic commissioning report which can be used for supplying certification documentation necessary for safety acceptance tests.
