Product Description:
The S406BA-SE is an axis module servo drive manufactured by Kollmorgen within the S400 Servo Drives series. The unit interfaces between a motion controller and a permanent-magnet motor, providing closed-loop current and velocity regulation for industrial automation tasks such as packaging, printing, or material handling. Because it supports SERCOS fiber-optic networking, the module can be integrated into multi-axis systems without discrete analog wiring. Its compact format also suits control cabinets where several coordinated servo axes must operate in a limited amount of space.
The drive delivers a continuous output of 6 A rms, while short-duty peaks reach 12 A rms, allowing additional acceleration for dynamic loads. A current form factor of 1.01 indicates the sinusoidal quality of the output waveform, which helps limit added motor heating. The pulse-width-modulated output bridge is clocked at 8 kHz, which lowers audible noise and improves torque linearity. The drive has 4 opto-isolated digital inputs for limit-switch or homing signals, and it provides 2 transistor digital outputs for drive-status signals to a PLC. SERCOS expansion provides deterministic communication, and the module does not contain a power supply, so it must be fed from an external DC bus. At rated current, internal losses amount to 40 W, and that heat must be removed by cabinet airflow.
Standby consumption is 15 W, and total heat at zero load remains low for energy-efficient cabinets. The permissible motor wiring spans inductances between 7.5 mH and 40 mH, so a wide range of coil designs can be driven without overcurrent trips. An IP20 housing confines live parts yet requires installation in a filtered enclosure. With a face width of 50 mm, a depth of 240 mm, and a weight of 1.7 kg, the drive occupies little rail space and fits neatly into compact multi-axis cabinets.
