Key Technical Notes
- Absolute Encoder: As part of the "KA" series, it features a 17-bit absolute encoder. This allows the motor to retain its position without needing to home after a power reset.
- Medium Inertia: Designed for applications where the load is prone to vibration or is significantly heavier than the motors rotor. The medium inertia provides better tuning stability.
- Voltage: This is a 400V class motor, typically used in large industrial plants with three-phase power.
- Protection: Rated IP65 with a built-in oil seal and keyway shaft, making it suitable for environments with cutting fluids or dust.
- Brake Status: The "RS" suffix indicates this model does not have an electromagnetic brake.
The Delta ECMA-KA1315RS is a high-stability, absolute-type actuator designed for 400V industrial networks. Its primary function is to provide precise, high-torque motion while maintaining position memory and mechanical stability under heavy loads.
Core Functions
- Absolute Position Memory: The 17-bit absolute encoder acts as a digital log of the motors physical location. It functions so that the machine knows its exact coordinates immediately upon power-up, eliminating the need for time-consuming "homing" cycles.
- Mechanical Dampening (Medium Inertia): Specifically designed to handle loads that are prone to vibration. The medium-inertia rotor acts as a buffer, ensuring the motor doesn't "jitter" or oscillate when moving mechanical parts with high friction or varying weight.
- Constant High-Torque Delivery: It provides a steady 7.16 Nm of torque at 2000 RPM. This makes it the "workhorse" for axes that need to push or lift steadily rather than just rotate at high speeds.
- Environmental Protection: The integrated oil seal and IP65 rating allow it to function reliably in harsh environments where it may be exposed to cutting oil, coolants, or heavy dust (common in CNC and textile factories).
Typical Applications
- CNC Feed Axes: Moving the X or Y table on a milling machine where cutting force is high.
- Automated Tool Changers: Where knowing the exact location of the tool holder is critical for safety and speed.
- Textile & Paper Winding: Maintaining constant tension in machines that roll up material.
