Product Description:

The CB03561-MZ is a servo amplifier produced by Kollmorgen and offered in the CD Servostar CD Drives series. As part of the Compact Drive product family, it conditions bus commands, monitors feedback, and modulates phase current so that a matched motor tracks programmed motion profiles in factory automation cells. By integrating the control loops into a slim panel module, the unit simplifies axis wiring for packaging, printing, and material-handling equipment. Its compact format also helps when multiple axes must be mounted close together in a control cabinet.

This drive exchanges setpoints and status over the SERCOS fiber-optic bus, giving deterministic cyclic data for multi-axis systems. The single differential analog channel uses 14-bit resolution, which is sufficient for precise torque override commands. Current regulation is refreshed at 16 kHz, and six opto-isolated digital inputs latch index, limit, or homing events with sub-microsecond latency. The inner velocity loop achieves a closed-loop bandwidth of 400 Hz, enabling stiff tracking during rapid profile changes without overshoot. One open-collector digital output can flag servo-ready or fault states, and motion memory allows storage of 16 profiles that can be sequenced by the host. An analog output mirrors process variables for external monitoring.

The control electronics draw logic power from an external 24 VDC supply, allowing the drive to remain communicative during a main power dropout. The power stage is rated at 3 A continuous, suitable for low-to-mid torque rotary axes, and overload can be sustained for 0.5 s before thermal limiting begins. Position feedback is processed from a sine encoder, which supplies high-resolution sine-cosine signals to the current and velocity loops. That feedback path helps the drive correct speed and position error during fast motion changes.
