Yaskawa JANCD-MMOIC-02 Circuit Board for Drives and PLC Chassis
The Yaskawa JANCD-MMOIC-02 is a versatile circuit board that serves as an interface and control module within Yaskawa drive systems and PLC chassis. It is engineered to manage digital and analog I/O signals, encoder feedback, and communication between the main controller and peripheral devices. This board is a key element in achieving precise motion control in servo and inverter applications.
Hardware Architecture
The board features a 32-bit RISC processor with integrated memory, capable of handling high-speed interrupt routines. It includes 16 digital inputs (24 VDC, sink/source), 16 digital outputs (transistor, 0.5 A), and 2 analog inputs (0-10 V) for current or voltage monitoring. Additionally, it has an incremental encoder interface supporting TTL and differential signals, with up to 10 MHz counting frequency.
Communication Capabilities
Onboard communication ports include a CAN-based MECHATROLINK interface for connection to Yaskawa servo drives, as well as RS-232 and RS-422 for general-purpose serial communication. The board can also interface with EtherCAT via an optional adapter, enabling real-time motion control networks.
Functionality in PLC Chassis
When installed in a Yaskawa PLC rack, the JANCD-MMOIC-02 acts as a coprocessor, offloading motion calculations and I/O scanning from the main CPU. It supports cyclic data exchange with the PLC backplane, allowing shared memory access for rapid data transfer. This architecture improves overall system throughput and determinism.
Configuration and Programming
Configuration is performed through Yaskawa's MotionWorks or SigmaWin+ software. Users can set input filtering, output default states, and scaling factors for analog channels. The board's firmware includes a library of motion function blocks, such as homing, interpolation, and cam profiling, which can be called from the main PLC program.
Applications
Typical uses include robotic axes, CNC machinery, packaging equipment, and web processing lines. The board's ability to handle both I/O and encoder signals makes it ideal for closed-loop position control systems. It is also employed in test stands and inspection machines requiring synchronized motion.
Protection and Diagnostics
Each I/O channel is protected against overcurrent and ESD. The board provides LED status indicators for power, communication, and error conditions. Built-in self-test routines check memory, analog references, and encoder signal integrity upon power-up.
Environmental Specifications
Operating temperature is 0 to 55°C, with humidity up to 90% non-condensing. The board is certified for CE and UL standards, and it conforms to RoHS directives. Vibration resistance is up to 5G at 10-500 Hz.
Installation and Maintenance
Installation requires careful handling of the board's edge connectors and alignment with chassis slots. Maintenance is limited to periodic visual inspection and firmware updates. The board's long-term reliability is supported by Yaskawa's quality manufacturing processes.
In summary, the Yaskawa JANCD-MMOIC-02 circuit board offers a robust, feature-rich solution for integrating I/O and motion control within a unified architecture, enhancing both flexibility and performance in advanced automation systems.
