Description
Kollmorgen S20630
Technical Specifications Series: S200 Servo Drives Continuous Output Current: 6 A RMS Peak Output Current: 18 A RMS Supply Voltage: 120/240 VAC or 20-90 VDC Velocity Loop Bandwidth: 800 Hz Current Loop Bandwidth: 3-5 kHz Update Rate: 0.8 µs PWM Carrier Frequency: 31.2 kHz
Performance Parameters The S20630 provides 500 W continuous output power when supplied from a 75 VDC bus. The drive can sustain 250 W output at 40°C ambient temperature. The DC link may be energized up to 90 VDC. The current loop responds at frequencies up to 5 kHz for precise torque modulation. Output current form factor remains stable across the operating range.
Functional Characteristics This drive incorporates all-digital control architecture with advanced servo algorithms. It supports SFD (Smart Feedback Device), Comcoder, and sine encoder feedback formats. The intelligent feedback system with electronic motor nameplate eliminates manual drive parameter setup for compatible motors. Control modes include torque, velocity, and position control with electronic gearing capability.
Structural Features The drive housing measures 152.4 mm in height with a narrow profile suitable for side-by-side mounting. The compact dimensions conserve DIN rail space in dense control cabinets. The enclosure design accommodates an internal feedback expansion card when optional feedback channels are required. High-density connectors minimize panel space requirements.
Installation Requirements Install on a conductive, grounded mounting plate within an industrial control enclosure. Connect DC bus power through appropriately rated conductors. Wire motor phases U, V, W to the output terminals. Connect feedback cables from the servo motor to the corresponding feedback port. Configure control signals through the digital and analog I/O terminals.
Operating Considerations Ensure at least 4000 µF external capacitance is present on the DC link for stable operation. Verify motor phase inductance exceeds 0.2 mH minimum requirement. The drive can sustain peak current for 3 seconds before thermal limiting. Protect the control stage with a 15 A fuse. Allow adequate ventilation to prevent overheating during continuous operation.
