Product Description:

The S30101-NA is a Kollmorgen motion controller in the S300 Servo Drives series. It is listed under the S300 Servo Drive product type and links plant power to servomotors used for speed, torque, and position regulation on automated machinery. By rectifying three-phase mains and pulsing an IGBT bridge, the unit converts line energy into precisely timed phase currents. Command and diagnostic data reach the drive through its CANopen onboard interface, allowing direct integration with PLC networks without additional fieldbus cards.

Rated operation spans an input window of 208–480 V, enabling deployment on both 230 V and 460 V systems. Continuous motor supply current is limited to 1.5 A rms, while maximum input demand is 1.2 kVA. The PWM bridge switches at 8 kHz; when the controller enters reduced-current mode, this carrier doubles to 16 kHz to lower acoustic noise. A monitored DC link ceiling of 900 VDC protects the bus capacitors, and the hardware-implemented STO circuit removes gate drive so torque production stops safely. Output symmetry is aided by an internal brake resistor of 91 Ω, and the residual 5 V drop across the output stage keeps commanded torque linear. Switch-on and switch-off cycles are limited to 30 per hour to help prevent electrolytic capacitor stress.

Energy rejected during deceleration is handled by an embedded chopper that channels up to 40 W into the internal sink, and an external element rated for 20 W continuous duty can be wired when higher thermal capacity is required. With an output current form factor of 1.01, RMS and mean currents remain nearly identical, which simplifies cable sizing. Cabinet layout is supported by a width of 70 mm and a depth of 171 mm. Heat losses are 12 W when the drive is disabled and 40 W at rated load. The reduced-current 16 kHz mode, 91 Ω shunt, and controlled regeneration path support operation without forced cooling.
