Engineered for high-performance multi-axis synchronization, the Mitsubishi Electric LD77MS16 provides advanced motion control capabilities directly integrated into the MELSEC L Series PLC platform. This module controls up to 16 axes through high-speed optical fiber communications, minimizing wiring complexity while ensuring immune response against industrial electromagnetic noise. Ideal for applications requiring synchronized speed, positioning, and complex electronic cam profiling, it serves as a central hub for complex motion paths in compact automation systems.
| Parameter | Specification |
|---|---|
| Manufacturer | Mitsubishi Electric |
| Model Number | LD77MS16 |
| Product Series | MELSEC L Series |
| Control Axes | Up to 16 axes |
| Servo Amplifier Connection | SSCNET III/H (1 system) |
| Control Cycle | 0.88 ms / 1.77 ms (configurable based on axes) |
| External Inputs | FLS (Upper limit), RLS (Lower limit), DOG (Near-point), STOP |
| Internal Current Consumption | 0.85 A at 5 VDC |
| Operating Temperature | 0 to 55 degC |
| Country of Origin | Japan |
| Shipping Weight (Calculated) | 0.35 kg |
| Port / Connector | Interface Function |
|---|---|
| CN1 (Optical Connector) | SSCNET III/H loop connection to servo drives (MR-J4-B / MR-J3-B) |
| Front Multi-pin Connector | Manual pulse generator, external inputs (FLS, RLS, DOG, STOP) |
While migrating from legacy rack-based platforms like the QD77MS16 (Q Series) to the LD77MS16, key programming architectures remain compatible within GX Works2. However, consider physical module layout differences; the L Series utilizes a rack-free bus connector. Ensure the base system has end covers installed on the final block to prevent communication line instability.
Pay strict attention to the 5VDC internal current budget. With a high draws of 0.85A, adding multiple motion or network units onto a single L Series CPU stack can easily overload standard power supplies, leading to intermittent CPU restarts or bus errors. Ensure the power calculation includes all connected expansion modules.
Keep SSCNET III/H optical fiber cables within their recommended minimum bending radius (typically 25mm to 30mm depending on cable class). Excessively tight bends attenuate optical signals, causing random network disconnects and "SSCNET communication error" faults on startup. Always clean the optical fiber ends with an approved swab before insertion.
