NSK EXEA1-0010A01-03 AC Servo Drive | Megatorque Motor System Controller | EXEA1 Series
Engineering Background: The NSK EXEA1 Series represents NSK’s dedicated servo drive platform engineered specifically for the Megatorque Motor direct-drive system — a high-torque, zero-backlash rotary actuator widely deployed in precision indexing, semiconductor handling, and multi-axis robotic applications. The EXEA1-0010A01-03 is the 1.0 kW rated controller variant within this series, providing closed-loop torque, velocity, and position control with full digital parameter management.
Product Positioning: Designed for OEM machine builders and system integrators requiring deterministic motion performance without mechanical transmission losses. This drive pairs exclusively with NSK Megatorque Motor assemblies and communicates via NSK’s proprietary serial interface, making it the authoritative replacement or expansion unit for existing EXEA1-based installations.

System Architecture & Signal Flow
The EXEA1-0010A01-03 operates as the central motion node in an NSK Megatorque Motor system. The host controller (PLC / motion card) issues position or velocity commands via pulse train or serial link → the EXEA1 drive executes real-time current loop control at the power stage → encoder feedback from the Megatorque Motor rotor closes the position loop → fault and status signals are returned to the host via dedicated I/O or serial status frames. Regenerative braking energy is dissipated through the internal resistor circuit (external resistor option available for high-duty-cycle applications).

Technical FAQ
Q: Is EXEA1-0010A01-03 compatible with all NSK Megatorque Motors?
A: The EXEA1 series is designed for NSK Megatorque Motors. Compatibility depends on the motor’s rated current and encoder type. Please provide your motor model number for confirmation before ordering.
Q: Can this drive be used as a standalone replacement without re-parameterization?
A: If replacing an identical EXEA1-0010A01-03 unit, parameter backup from the original drive (via NSK EXEA1 setup software) is strongly recommended before swapping. Default factory parameters may not match your machine tuning.
Q: What communication cable is required between the drive and host PLC?
A: NSK specifies a shielded RS-422 cable for the serial interface. Maximum recommended cable length is 10 m. Refer to NSK EXEA1 Series User Manual (Doc. No. RA-TM-0001) for wiring diagrams.
Q: Is an external regenerative resistor required?
A: For standard duty cycles, the internal resistor is sufficient. High-inertia loads or rapid deceleration cycles may require the optional external resistor — consult NSK application guidelines or contact Konmask technical support.
Q: Do you provide the NSK EXEA1 parameter setup software?
A: Yes, setup software and the English user manual can be provided upon request with purchase. Contact support@konmask.com.
