220V Fieldbus Linear Motor Drive 5.5A - JALD7502-20B-EC General Series

A 220 V General Drive for Fast Linear Axes

The JALD7502-20B-EC is a 220 V fieldbus linear motor drive with a 5.5 A output, part of the JALD general series. Its ARM+FPGA current loop delivers high dynamic response, which matters on axes that must accelerate quickly and settle without overshoot.

How the Loop Stays Tight

The internal disturbance observer rejects external disturbances so the position loop sees a cleaner error signal. Multi-mode control covers different motion profiles, and auto-tune adapts the loop to the actual attached inertia rather than relying on nameplate values.

Application Scenarios

This drive suits fast, short-stroke axes where response speed sets the cycle time:

• CNC machine tools: rapid positioning and tool-setting axes on machining and measuring machines.
• Semiconductor equipment: high-speed pick-and-place and inspection stages.
• Battery manufacturing: indexing and stacking axes that must settle quickly between cycles.
• Laboratory equipment: automated sample stages that shuttle between workstations.

Selection and Commissioning Advice

Match dynamic response to the load

5.5 A supports moderate linear motors; for heavier loads, move up the JASNLD flagship line rather than pushing this drive beyond its current rating.

Commission on site with microUSB

The microUSB port simplifies on-site commissioning, and FOE allows firmware upgrades over the network, so distributed machines can be updated without a technician visit.

Plan the feedback and I/O

Configure the I/O for the machine’s sensors before tuning, and use the disturbance observer to verify the axis rejects external load changes during production.
