SD2

The Drive Solution for Multi-Axis Systems and High Powers

How about a second channel? The universal drive amplifier SD2 for machine controls is available as one-channel or as two-channel versions. Linear motors, rotary servo motors, high-pole torque motors as well as synchronous /asynchronous tool spindles with or without sensor can be driven by the SD2. The specialty: Synchronous and asynchronous motors can reach speeds up to 480,000 rpm.

For the connection to a higher-ranking control analog reference values (+/-10 V) or pulse-direction values are processed. Alternatively, a CNC control can be connected via the bus system SERVOLINK 4. SIEB & MEYER offers a SERVOLINK 4 PCI plug-in board for a PC-based control. The used optical fiber technique ensures a troublefree fail-safe connection between the CNC control and the drive amplifiers.

Universal Motor Encoder Interface – SD2 evaluates all common measuring systems for rotary and linear motors, starting with A as absolute value encoders with EnDat, Hiperface or SSI interface, encoder, magnetoresistive sensor, Hall effect sensor, linear Hall sensor, linear scale with 1Vpp or TTL level up to R as resolver.
Safety Integrated – The currently effective safety category 4 can be reached by the integrated restart lock. As external protective circuits can be reduced, system costs are minimized.
Flexible Cooling – The standard version of SD2 is delivered with an integrated heat sink. Optionally, the heat sink can be delivered as cool plate version. This allows using liquid cooling, mounting plug-through heat sinks or installation of air-cooled lamella heat sinks.

SD2 – Multi-Axis Concept

The multi-axis drives in two-channel design are suitable for machines with several moving axes. Energy is supplied to the connected SD2 drives from the power supply module PS2. Together with the SIEB & MEYER servo motors this forms a compact and cost-optimized drive package.

SD2 – Compact Device

The devices with integrated power supply are suited for applications with only a few drives. That way an X-Y table can be operated via just one SD2 drive. This compact device combines power supply and two drives in one housing. This is surely the easiest way to integrate the power electronics into your control.
