Main Features and Advantages
Four-Quadrant Operation with V-MOS Technology: The Kollmorgen 04S-M60/8-PB employs a pulse-width modulated transistor stage built with V-MOS transistors, enabling efficient four-quadrant operation of DC motors. This architecture allows the drive to control motor speed and torque in both directions of rotation and in both motoring and generating modes, making the Kollmorgen 04S-M60/8-PB suitable for applications requiring rapid directional changes and regenerative braking capability.
Integrated Ballast Circuit with Soft Characteristic: A distinctive feature of the Kollmorgen 04S-M60/8-PB is its built-in ballast circuit with a “soft” characteristic. When the motor decelerates and feeds energy back into the DC-link, the ballast circuit dissipates excess energy as heat in an external ballast resistor. The “soft” characteristic causes the switch-on threshold to rise from 85V to 90V under repetitive loading, enabling effective power sharing when multiple Kollmorgen 04S-M60/8-PB modules operate in parallel on the same DC-link bus.
Flexible Feedback Configuration with IxR Regulation Option: The Kollmorgen 04S-M60/8-PB supports both tachometer feedback and armature voltage (IxR) regulation, selectable via solder links on the controller board. This flexibility allows the drive to be adapted to different motor types and application requirements without external hardware changes. The tachometer input features a wide adjustment range from 8V to 75V, accommodating various tachogenerator specifications.
PLC-Compatible Isolated Control Interface: All digital control inputs on the Kollmorgen 04S-M60/8-PB are electrically isolated by optocouplers, ensuring compatibility with standard 24V PLC logic systems while protecting the control electronics from ground loops and electrical noise. The enable input, limit-switch inputs, and integral-off input all operate at logic levels of 12V to 30V with a typical current draw of 8mA, facilitating straightforward integration into existing automation architectures.
Comprehensive Protection and Monitoring: The Kollmorgen 04S-M60/8-PB incorporates multiple protective functions including short-circuit and earth-fault protection at the motor terminals, overvoltage monitoring, output stage temperature monitoring, and I²t monitoring for both the amplifier and motor. A system-ready relay with a floating contact enables the drive to participate in the machine‘s safety circuit, ensuring that the operational readiness of the Kollmorgen 04S-M60/8-PB is continuously monitored.
