Digital MMC-D4 by Kollmorgen

The Digital MMC-D4 from Kollmorgen is a high-performance controller in the MMC Standalone Smart Drives series, engineered to manage up to four motion axes with precision and reliability. Equipped with a 32-bit RISC CPU and integrated numeric coprocessor, it delivers accelerated execution of complex control algorithms. The module features 1 MB of memory for program storage and a 2 MB flash disk for firmware updates and data logging. Designed for industrial automation, its sourcing-only DC inputs conform to IEC Type 1 (IEC 1131-2) standards, ensuring robust and flexible integration with standard 24 VDC power systems.

This smart drive controller offers versatile connectivity options to support demanding automation networks. The secured RS232 PICPRO port operates at up to 115 200 baud with RTS/CTS handshaking, while the RS232/RS485 user port provides flexible serial communications for peripheral devices. An IEEE 802.3/802.3u-10/100Base-TX half-duplex Ethernet port enables seamless integration into plant LAN infrastructures for remote diagnostics and control. The eight DC outputs deliver nominal 24 VDC (30 VDC max) at 0.25 A per channel, suitable for direct actuation of sensors and actuators. MMC/SD drive inputs accept 20–30 VDC at 250 mA, simplifying field wiring and ensuring consistent operation under varied load conditions.

For reliable operation in industrial environments, the Digital MMC-D4 is powered by a 3 V BR2032 lithium coin cell that sustains the real-time clock, which maintains ±1 s/day accuracy at 25 °C and ±2 s/day across ambient conditions. The controller’s sourcing-only inputs and outputs offer high noise immunity and durable performance in electrically noisy settings. Compliance with IEC Type 1 input classifications underscores its adherence to recognized safety and quality standards. By combining advanced processing capabilities, extensive memory, and flexible I/O interfaces, the Digital MMC-D4 optimizes synchronization and responsiveness in multi-axis automation, enhancing throughput and reducing system complexity in industrial applications.
