Product Introduction
BSD0750 is an ABB BSD Series AC servo amplifier with a 750 W capacity, designed for servo motor control in 200–230 VAC electrical systems. ABB documentation identifies BSD0750 as the 0.75 kW amplifier in the BSD family and specifies compatibility with the 750 W BSM servo motor range.
The amplifier supports either single-phase or three-phase 200–230 VAC main power at the 0.75 kW level. ABB specifies a 17-bit incremental serial encoder for feedback, IGBT PWM sine-wave control, a 10 kHz carrier frequency, and 300% overload resistance for approximately three seconds.
For replacement and maintenance requirements involving older BSD motion systems, BSD0750 provides a compact servo-control solution combining position, speed and torque control functions with encoder feedback, regenerative braking capability and configurable control interfaces.
Electrical & Servo Control Characteristics
BSD0750 belongs to the lower-capacity section of the ABB BSD Series and uses Frame 2 construction. ABB's documentation places BSD0750 alongside the BSM0750 motor family, with the corresponding 750 W motor operating at 3000 r/min.
The main power arrangement is particularly important when identifying a replacement. For BSD0750, ABB permits either single-phase or three-phase 200–230 VAC input. Single-phase power is connected through L1/L2, while three-phase power uses L1/L2/L3. The allowable voltage fluctuation differs between the two arrangements.
The control power supply is separately specified as single-phase 200–230 VAC at 50/60 Hz. The servo amplifier uses a 17-bit serial incremental encoder and provides speed-control accuracy of 1:5000 at rated load.
Control Functions
BSD0750 supports three principal servo-control modes:
- Position control
- Speed control
- Torque control
The control architecture includes sequence inputs for switching control functions and analog command inputs for speed and torque. Pulse-train command interfaces are also provided for positioning-related applications.
The amplifier includes functions such as notch filtering, automatic tuning, automatic offset adjustment, anti-vibration filtering and simulated encoder output. ABB documentation also describes an integrated configuration environment with a digitizing oscilloscope function for servo adjustment.

Feedback and Communication
The 17-bit serial encoder provides 131,072 actual pulses per revolution. Simulated encoder output can also be configured for different pulse-per-revolution values.
The RS-485 interface uses a four-wire half-duplex arrangement and supports TTY protocol communication at 9600, 19200 and 38400 bps. Station numbers can be assigned from 1 to 31.
These interfaces allow BSD0750 to participate in established servo control architectures where feedback, command signals and sequence control need to remain compatible with the original installation.
Matching Servo Motors
ABB identifies BSD0750 with the following 750 W BSM motor variants:
- BSM0750CN00 - 750 W servo motor without brake
- BSM0750CB00 - 750 W servo motor with brake
The BSD0750 / BSM0750 combination belongs to the 3000 r/min low-inertia section of the BSD/BSM product family.
When identifying a replacement amplifier, matching the amplifier capacity and the installed motor family is important because the BSD Series uses different amplifier and motor combinations across its 100 W to 2 kW range.
Installation and Environmental Conditions
BSD0750 is designed for indoor installation and uses a Frame 2 enclosure. ABB specifies an operating temperature range of -10 to +55°C with relative humidity from 10% to 90%, without condensation.
The amplifier is intended for 200 V-class commercial power and should be connected according to the applicable BSD wiring arrangement. ABB specifically distinguishes the single-phase and three-phase connection requirements for the 0.75 kW BSD0750.
Lifecycle Information
BSD0750 is identified by current secondary-market product listings as discontinued by the manufacturer.
Because of its discontinued status, the exact model number should be retained when identifying an existing installation. Substituting another BSD model solely because it has a similar power rating may not provide the same electrical, feedback or control characteristics.

Frequently Asked Questions
What is the ABB BSD0750?
BSD0750 is a 750 W servo amplifier from ABB's BSD Series AC Servo System. ABB's product documentation lists it as the 0.75 kW amplifier for the BSM0750 servo motor family.
Is BSD0750 a single-phase or three-phase amplifier?
BSD0750 supports both single-phase and three-phase 200–230 VAC main power. The applicable wiring and voltage tolerance depend on the selected phase arrangement.
What motor is associated with BSD0750?
ABB identifies BSD0750 with the 750 W BSM0750 motor family, including BSM0750CN00 and BSM0750CB00 variants.
What type of encoder does BSD0750 use?
BSD0750 uses a 17-bit serial incremental encoder, corresponding to 131,072 actual pulses per revolution.
What control modes are available on BSD0750?
The BSD Series supports position, speed and torque control. The selected control function can be switched through sequence input functions.
Is BSD0750 still manufactured?
Secondary-market listings identify BSD0750 as discontinued by the manufacturer. For an existing BSD installation, the exact model and electrical characteristics should therefore be checked carefully when sourcing a replacement.
What is the overload capability of BSD0750?
ABB specifies 300% overload resistance for approximately three seconds for the BSD0750 class.
Does BSD0750 have a built-in brake function?
The BSD Series incorporates regenerative braking functionality, and external regenerative resistance can be connected to the DC link when required by the application.
