Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a B&R Industrial Automation part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These series from our supply network is the closest match on published figures.
A dual-axis low-voltage Kinco drive for AGV differential-drive wheels, with RS + CANopen or RS + pulse variants and built-in brake output.

A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
What a multi-axis servo drive is
A multi-axis servo drive controls two or more servo motors from one unit, usually sharing a power supply, DC bus and communication interface. Formats include compact two- to four-axis drives in one housing and modular systems with a common supply module and separate axis modules. Sharing the bus lets energy from a decelerating axis be used by others, reducing braking losses. Most connect to a motion controller or PLC over EtherCAT or another industrial Ethernet network.
When engineers choose a multi-axis servo drive
Choose a multi-axis drive for machines with several coordinated servo axes in one cabinet, such as robots, packaging machines and gantries. It saves space, wiring and cost per axis compared with single drives. The trade-offs are flexibility and fault isolation: axes share the supply, so a supply fault affects all axes, and replacing one module may need specific spare strategy. Mixing very different power levels can be limited by module ranges.
How to specify the B&R Industrial Automation ACOPOS P3
Send these with your enquiry and an engineer can confirm the right ACOPOS P3 variant or an equivalent:
- Number of axes and power per axis (A, kW)
- Supply voltage (V AC or DC)
- Network interface and cycle time
- Motor and feedback types
- Shared bus and regenerative energy handling
- Safety functions per axis
- Cabinet size and cooling
Common mistakes to avoid
- Sizing supply module for the sum of peaks without considering simultaneous demand
- Ignoring how one fault affects all axes
- Choosing modules without room for future axes
- Overlooking network cycle time with many axes
B&R Industrial Automation ACOPOS P3: frequently asked questions
What is the B&R Industrial Automation ACOPOS P3?
Compact 1-, 2- and 3-axis servo drives from 0.7 kW to 80 kW per module with a 50 µs sampling time, available with SafeMOTION. Published series figures include power 700 W, power 80,000 W. It is made by ABB; Specify Motion can help source it or propose an equivalent.
Who makes the B&R Industrial Automation ACOPOS P3?
The B&R Industrial Automation ACOPOS P3 is made by B&R Industrial Automation (ABB) and is listed here for engineers comparing options. Specify Motion is not affiliated with ABB; brand names are used only to identify the product.
What is the power of the B&R Industrial Automation ACOPOS P3?
The published series minimum power is 700 W. Individual models and sizes in the ACOPOS P3 range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the B&R Industrial Automation ACOPOS P3?
Yes. On published figures, Kinco FDS Two-in-One Low-Voltage DC Servo Drive (FDS-AB/CB/LB-D) is the closest match from our supply network. An engineer confirms the fit against your application before recommending anything.
What are the benefits of a shared DC bus?
On a shared DC bus, energy regenerated by a decelerating axis can be used by other axes that are accelerating, reducing the energy dissipated in braking resistors. It also reduces wiring and supply components. Sizing must consider simultaneous peak demand on the shared supply.
Are multi-axis drives cheaper than single-axis drives?
Typically, per axis, multi-axis drives cost less and take less cabinet space, because the supply, communication and housing are shared. The saving grows with the number of axes. For machines with only one or two axes, or widely separated axes, single drives can be simpler.
