This servo amplifier is mounted vertically onto the backplane of a switchgear cabinet. The product should not be operated with the doors of its cabinet in the open state. This device uses a standard industrial Ethernet cable and connectors for the Profinet expansion card. The unit comprises a RS 232 serial interface for its connection to a PC. It is controlled by a secondary feedback system when the electronic gearing functionality is implemented. This amplifier is parameterized using the DRIVEGUI.EXE setup software.

The product comes along with a shielding plate and shield clamps, a copy of the product safety guide, and a CD-ROM with the setup software and online documentation. The device associated cables and mating SubD connectors have to be ordered separately. This unit is designed to be exclusively used in industrial environments. Its nameplate encompasses a 2D barcode and certification details apart from technical data.

The servo amplifier does not contain hazardous substances like CMR, vPvB, and CMR substances that have an adverse effect on the environment. This product comes fitted with five mating connectors. The device comes with a safe stop STO function and a position controller onboard. The unit features a large supply voltage range of 3 x 208 to 480 VAC with +/-10% tolerance. Its memory card slot is located on its top. This amplifier has a power section that supports a single-phase supply operation.
