Product Description:
The PA5000 indexer driver is produced by Kollmorgen within the 5000 Indexer Drivers series. It serves as both a power stage and a motion coordinator for servo axes used in automated assembly cells, packaging lines, and material-handling stations. The unit rectifies incoming mains power for the motor bus and generates the pulse commands needed to control axis position during programmed machine cycles.
The unit accepts a 230 VAC three-phase input with an apparent power demand of up to 20 kVA and converts the supply to a 310 VDC bus. During continuous operation, output current is limited to 50 A. Temporary overloads are supported by peak currents of 75 A for 2 seconds and 100 A for 50 milliseconds, allowing the drive to accelerate large inertial loads without immediately entering current limiting. Internal power dissipation is 200 W, and regenerative energy can be routed to an external 4.5 Ω shunt when the capacitor network reaches its 390 VDC activation threshold. The regenerative capacitor network has a capacitance of 0.00392 F, and regeneration stops after the bus voltage falls below 370 VDC. A fault contact closes within 250 milliseconds and can switch 1 A at 115 VAC, providing a hardwired status signal for a safety relay or PLC input.
The driver provides an output capability of 15.5 kW, supplying the mechanical system with substantial power for coordinated motion. An overtemperature trip activates at 90 °C to protect the power semiconductors from excessive heat. Startup inrush is controlled by a soft-start network that limits capacitor charging current for 0.75 seconds, reducing electrical stress on supply breakers and internal components. Cabinet ventilation must accommodate the heat generated during sustained operation, while the external dump circuit must have sufficient thermal capacity for surplus kinetic energy returned by decelerating loads. The dedicated fault signal gives the surrounding control system a direct indication when drive operation is interrupted, allowing the machine sequence to respond through its configured interlocks.
