Main Features
The SDB Series is a digital converter designed for sinusoidal brushless motors, offering high dynamic response suitable for various applications. Key features include resolver auto phasing, automatic current loop gain calibration, and resolver resolution self-adjustment for precision across speed ranges. It supports configurable simulated encoder output and includes a monitor software for parameter setting and monitoring.

Fieldbus and Special Functions
The drive includes electrical gearing, master/slave functions, and a multipositioner with 12 programmable positions. It offers programmable profiles, a digital potentiometer for frequency input, and step motor function with position loop control. Communication is facilitated through RS485/RS232 serial interface with Modbus protocol.

Options
Available options include CAN BUS and PROFIBUS DP interfaces, opto-isolated simulated encoder output, RS232/485 adapter for PC, remote keypad for parameter setting, and clamping resistors.

Power Specifications
The drive features a built-in clamping circuit, output frequency range of 0 to 400 Hz, and diagnostic capabilities via display or serial line. It includes a soft-start circuit and supports an AC voltage supply range of 3 x 200 Vac to 440 Vac ±10%.

Control and Regulation
The SDB Series offers full digital regulation with independent ramps in four quadrants, eight opto-isolated configurable digital inputs, and three programmable speed references. It supports analog and digital inputs for speed, torque, and current limit references, along with four opto-isolated digital outputs and two programmable analog outputs.

Technical Data
