The VFX 2.0 is available in either NEMA 1 or NEMA 12 configurations. The robust steel construction of the NEMA 12 version provides the ability to install the drive close to the application, eliminating the cost of cabinets and long motor cables.

Built-in load monitoring and unique Load Curve Protection functionality protect your process by immediately detecting any situation that could cause inefficiency or damage. Early warnings and safety stops for over- and underloads allow preventative action.

A crane I/O expansion board offers efficient hoist and travel drive and a safety system that activates the mechanical brakes should dangerous loads be detected. Also provides load dependent field weakening functions for hoist drives.

Communication options include Fieldbus communication via Profibus and DeviceNet, Industrial Ethernet communication via Modbus/TCP, EtherCAT and Profinet, and serial communication via RS232 or RS485 with Modbus RTU.

PTC and PT100 sensors can be connected to control motor temperature and give process feedback without using a transmitter.

This option board offers protection from unexpected start during mechanical maintenance, in accordance to the EN954-1 Category 3 standard. No contactor is required.

Units from 90A can be provided with liquid cooling. This allows for reduced operating and maintenance costs, and the cabinet can have a protection class higher than IP54/NEMA 12.

A 1st environment category 2 EMC filter is available as a factory-mounted option.

A 12-pulse rectifier offers a cost-efficient reduction of harmonic current distortions. It reduces power losses in equipment such as transformers and conductors, and eliminates the need to over-size these components.

A standby supply makes it possible to supply the control circuits via an external 24 VAC/DC supply to maintain communication and set up the system when 3-phase mains is not connected. Provides communication backup if 3-phase main power supply fails.

A top cover drip protection available for IP20/NEMA 1 units 11-132 kW if units are wall mounted in an electrical room.

An HTL or TTL encoder can be connected for more accurate speed control or for increased safety through deviation control in crane applications.

For short braking time, our continuous braking chopper is available as a factory-installed option. It is used in combination with brake resistor dimensions according to the specific application demand.
