Kollmorgen S30301-EC
Product Type: Digital AC Servo Drive (Economy / Compact Class)
Product Brief:
The S30301-EC is a cost-optimized single-axis servo drive from Kollmorgen’s S303 family. The “EC” suffix typically denotes the EtherCAT communication variant with compact I/O. It targets applications requiring reliable motion control at a lower price point than the S306.

Functional Features:
- Simplified motion control: Position, velocity, and torque modes without advanced camming
- Automatic motor tuning via Kollmorgen Workbench
- EtherCAT slave with distributed clock (DC)
- Electronic gear ratio up to 2³²:1
- STO safety function (Safe Torque Off)
Structural Characteristics:
- Compact DIN rail mount enclosure
- Pluggable terminal blocks
- Single LED status indicator (Ready/Fault)
Applicable Industries:
- Simple conveyor axes
- Valve actuation
- Gate and barrier operators
- Small pump drives
- Basic robotics axes
Installation Requirements:
- DIN rail mount (35 mm TS-35 rail)
- Minimum 20 mm clearance on all sides for airflow
- Use 1.5 mm² minimum wire for power connections
Usage Notes:
- The S303 is a stripped-down version of the S306 — it lacks the advanced camming and high-speed interpolation features
- Suitable for applications where cycle time of 500 µs is acceptable
