Servo Amplifier SD4S
The product version SD4S - S for Stand-alone - is the first device of the new product series SD4x. The SD4S devices are designed for stationary use in control cabinets of machine tools, turbo compressors and turbo blowers. No matter if linear motor, rotary servo motor, high-pole torque motor or synchronous/asynchronous tool spindle with or without sensor, the SD4S masters all these drive types.
Analog reference signals (+/-10 V), CANopen, EtherCAT (CoE) signals / protocols are processed for connection to the higher-level controller.
Highlights
Better Performance and New Control Functions
The first available unit type is designed for small high-speed spindles or motors in the power range from a few hundred watts to 1 kW. Application areas are e.g. dental milling machines or machines for super finishing as those required in watchmaking. Since small spindles do not come with a sufficient insulation resistance in the motors, SD4S now features a galvanic isolation of the thermal contact.
An absolute novelty is the design width of 40 mm only. Particularly in applications with many axes and a low performance, the demand for highly compact drive systems is great. Thus, the construction volume has been further reduced. The parameterization is realized via a default Ethernet interface that replaces the USB interface, which in industrial environments is prone to failure.
Moreover, SD4S comes with programmable digital measuring system interfaces such as Biss-C, EnDat2.2 and TTL. Via a Webserver, technicians can display device information without the need of additional parameterization software. Thanks to the real-time clock, a time synchronization of an incident is possible: Users can figure out whether a failure has been caused for example by a thunderstorm.
The optimized performance, higher speeds as well as the lower motor heating without sine-wave filter are substantial advantages of SD4S.

Drive Functions and Safety Functions
Software for Initial Operation and Parameterization: drivemaster4
The parameterization, simulation and diagnostic software drivemaster4 enables the user to commission drive systems easily and quickly. With the integrated simulation tool Motor Analyzer, the user can already prove at the time of system design that the desired system characteristics in terms of operating points and harmonics can be realized. The basis for this is suitable electrical motor data.
Simulation:
- Electrical operating points
- Influence of PWM frequency/converter topology
- FFT analysis including THDi/THDu calculation
- Export of simulation data
Start-up:
- Parameterization of the motor data/interfaces
- Optimization by means of oscilloscope
- Commissioning tool
Monitoring:
- Data logger
- Real-time clock
- Error memory
- Operating hours counter
