Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Mitsubishi Electric part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 3 series from our supply network are the closest match on published figures.
A four-axis EtherCAT servo drive in one housing, 400-1500 W per axis on 220 or 400 VAC, with two STO circuits shared across the axes.
View series →A dual-axis EtherCAT version of the EL6, 400-1500 W per axis with two encoder inputs.
View 2EL6-EC Two-Axis EtherCAT AC Servo Drive →A dual-axis version of the ELD2 for 24-70 VDC systems: 20 or 30 Arms per axis (750 W or 1.2 kW per axis), gantry synchronisation and STO, saving around 30% installed volume versus two single drives.
View 2ELD2 Two-Axis DC Servo Drives →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.
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 Mitsubishi Electric MELSERVO-J5 MR-J5D drive units
Send these with your enquiry and an engineer can confirm the right MELSERVO-J5 MR-J5D drive units 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
Mitsubishi Electric MELSERVO-J5 MR-J5D drive units: frequently asked questions
What is the Mitsubishi Electric MELSERVO-J5 MR-J5D drive units?
Multi-axis servo drive units with one, two or three axes on a common DC link, paired with the MR-CV regenerative converter unit, for CC-Link IE TSN systems. It is made by Mitsubishi Electric Corporation; Specify Motion can help source it or propose an equivalent.
Who makes the Mitsubishi Electric MELSERVO-J5 MR-J5D drive units?
The Mitsubishi Electric MELSERVO-J5 MR-J5D drive units is made by Mitsubishi Electric (Mitsubishi Electric Corporation) and is listed here for engineers comparing options. Specify Motion is not affiliated with Mitsubishi Electric Corporation; brand names are used only to identify the product.
Is there an alternative to the Mitsubishi Electric MELSERVO-J5 MR-J5D drive units?
Yes. On published figures, Leadshine 4EL7-EC Four-Axis EtherCAT AC Servo Drive and Leadshine 2EL6-EC Two-Axis EtherCAT AC Servo Drive are 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.
