Figures are the highest published for each series and are not always measured the same way. 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.
Typical applications
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 Inovance SV660ND dual-axis
Send these with your enquiry and an engineer can confirm the right SV660ND dual-axis 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
Inovance SV660ND dual-axis: frequently asked questions
Can you help replace Inovance SV660ND dual-axis or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Inovance SV660ND dual-axis?
Dual-axis EtherCAT servo drive for single-phase 200–240 V AC supplies, 0.4–0.75 kW per axis, with 23-bit encoders and selectable SIL 3 STO. Published series figures include power 750 W, axes 2, resolution 23 bit. It is made by Shenzhen Inovance Technology Co., Ltd.; Specify Motion can help source it or propose an equivalent.
Who makes the Inovance SV660ND dual-axis?
The Inovance SV660ND dual-axis is made by Inovance (Shenzhen Inovance Technology Co., Ltd.) and is listed here for engineers comparing options. Specify Motion is not affiliated with Shenzhen Inovance Technology Co., Ltd.; brand names are used only to identify the product.
What is the power of the Inovance SV660ND dual-axis?
The published series maximum power is 750 W. Individual models and sizes in the SV660ND dual-axis 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 Inovance SV660ND dual-axis?
We can assess suitable replacement options. On published figures, Leadshine 2EL6-EC Two-Axis EtherCAT AC Servo Drive and Leadshine 2ELD2 Two-Axis DC Servo Drives are options to assess 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.
