PMM-BA-5612 by Sanyo Denki

The Sanyo Denki PMM-BA-5612 servo drive represents a compact and efficient solution within the PMM PentaSYN Servo Drives series, providing precise motor control in industrial automation environments. This lightweight unit weighs just 45 g and measures 56 x 12 mm, enabling integration into space-constrained control cabinets without compromising performance. Its robust aluminum alloy construction with an anodized finish ensures mechanical durability and resistance to surface wear in demanding applications. Designed to handle a maximum mechanical load of 500 N, the PMM-BA-5612 facilitates reliable torque translation between controller and motor. The drive operates seamlessly across wide temperature extremes, delivering dependable service across varied industrial settings.

Detailed engineering specifications define the PMM-BA-5612’s capabilities. Critical structural parameters include a mounting type: bolt-on interface with M6 thread size and dimensional tolerance of ±0.05 mm, guaranteeing repeatable installation accuracy. The drive’s enclosure incorporates corrosion-resistant surfaces, denoted by Corrosion Resistance: Yes, to guard against harsh environmental conditions. Thermal operating limits span from –40°C to 85°C, enabling prolonged duty cycles in both cold storage and high-temperature production areas. With an input voltage range of 100 to 115 VAC and support for 50-60 Hz line frequencies, this unit accommodates international power standards without additional converters.

Operational features emphasize real-time status monitoring and thermal management. A vertically mounted LED bar on the front panel provides clear indication of power state (POWER) and normal operation (MON) in green, while fault conditions such as position error (P.E), overload fault (O.F), and overheat (O.H) are flagged in red. Integrated ventilation slots on top and side panels, combined with a rear-mounted cooling fan, facilitate efficient heat dissipation during continuous operation. The drive’s low mass and compact profile reduce inertia on motion axes, enhancing dynamic response and repeatability in high-precision positioning tasks. Front-accessible wiring terminals streamline field installation and serviceability, minimizing machine downtime in maintenance cycles.

System integration of the PMM-BA-5612 is achieved through a structured front terminal block, where motor windings connect via U, V, W outputs and status lines interface through labeled points such as ALM (alarm), RDY (ready), and MON (monitor). Signal routing is color-coded for BLACK, RED, and ORANGE leads, simplifying configuration of feedback sensors and encoder inputs. Compact flange mounting and universal input compatibility make this drive ideal for robotics, packaging machinery, CNC auxiliary axes, and other industrial automation platforms requiring precise, low-profile servo solutions. Its combination of robust mechanical design and streamlined electrical interfacing ensures rapid integration into existing control architectures.
