PMM-BA-4804-1
The Sanyo Denki PMM-BA-4804-1 is a high-precision driver in the PM Drivers series designed for micro stepper motor control in demanding industrial automation environments. Its compact enclosure offers robust protection against dilute acids, dilute alkali, and mineral oil, and accommodates installation within switchgear cabinets meeting at least IP54 standards. The unit integrates multiple LED display indicators for real-time monitoring of power status, phase origin, pulse signals, and error conditions. Designed for single-phase power input, the PMM-BA-4804-1 delivers reliable performance with an AC Source Voltage: 100V supply at 50–60Hz, and an adjustable Rated Current: 6A/phase (changeable to 4A/phase) configuration. Critical protection against overheating is provided by a built-in Protection Function: against PM driver overheat, ensuring continuous operation under heavy load.
The driver’s electrical characteristics are precisely defined to optimize motor control. It features Insulation Resistance: 10MΩ or more (DC500V) for enhanced safety and dielectric stability, and supports a Max Input Frequency: 100kpulse/s to accommodate high-speed pulse inputs. The Input Signal Voltage (CW/CCW): H = 4.0 to 5.5V, L = 0 to 0.5V enables compatibility with a range of pulse generator outputs. Ambient operating conditions are well delineated, with an Operating Ambient Temperature: 0 to +50°C tolerance and Operating Ambient Humidity: 35–85% RH (no condensation). For storage, the device withstands a Conservation Temperature: –20 to +70°C range. The wire-wound current capability is specified as Wire-wound Current: 6A/phase, and the mechanical coupling yields a Getaway Torque: 15.1×10−4 kg·m² (rubber coupling).
Operational reliability is further enhanced by features that address power interruptions and overload conditions. The Power Down Function: enabled by signal input allows controlled shutdown sequences to prevent motor runaway. An Automatic Current Down Feature: selectable mode reduces phase current under idle conditions, minimizing heat generation and extending driver life. Vibration resilience is confirmed at Vibration Resistance: 4.9 m/s² (10–55Hz) across all axes, ensuring stable operation in machinery subject to mechanical shock or ambient vibration. The driver’s Alarm Monitor: relay contact output (DC24V, 0.5A or less) provides fault signaling for integration with supervisory control and data acquisition systems.
System integration is streamlined through standardized interface signals and mounting provisions suited for control cabinets in automated assembly, packaging, robotics, and positioning systems. The PMM-BA-4804-1’s adherence to IP54 protection, combined with its compact form factor, makes it ideal for retrofitting existing equipment or designing new machines with space constraints. Engineers benefit from straightforward wiring of CW/CCW pulse inputs and power supply lines, while the driver’s diagnostics outputs facilitate rapid commissioning and maintenance. In summary, the Sanyo Denki PM Drivers series unit offers a balanced combination of precision, durability, and integration flexibility for diverse industrial automation applications.
