Product Description:
The S20330-CNS-020 servo drive is manufactured by Kollmorgen and belongs to the S200 Servo Drives series. Designed for low-voltage motion platforms, this unit delivers closed-loop control to brushless servomotors in compact machinery, pick-and-place axes, and light material-handling stages. Operating from a low-voltage DC bus and coordinating over a CANopen network, the drive functions as a position node so it can execute point-to-point moves commanded by a PLC or motion controller. Integrated SFD and Hall feedback support allows direct connection to Kollmorgen SmartFeedback Devices without additional interface cards, while optional SynqNet modules expand compatibility with sine encoders and EnDat 2.1 transducers.
Electrical output capacity is matched to small-frame motors. The nominal DC link is rated at 90 VDC, delivering a continuous phase current of 3 ARMS and a surge capability of 9 ARMS during acceleration. That current provides a continuous shaft power of 250 W and can momentarily rise to a peak apparent power of 750 VA for short overloads. Current regulation is handled by a digital loop with a bandwidth of 5 kHz, allowing tight torque linearity even when load inertia varies. No additional electrical options are required, which simplifies panel wiring and keeps the overall footprint consistent.
In velocity mode, the servo amplifier responds rapidly thanks to a loop bandwidth of 800 Hz, while the PWM stage operates at an output ripple frequency of 31.2 kHz to minimize audible noise and motor heating. The drive trips on bus overvoltage at 91 VDC, providing protection against regenerative events during fast deceleration. During peak events, it sustains overload conditions for up to 3 s before foldback mechanisms engage. Parameter sets for CANopen communication, SynqNet option cards, and the SFD/Comcoder interface reside in non-volatile memory, so stored settings remain available after power cycles.
