Product Introduction
Kollmorgen S70302-NANANA S700 Servo Drive Overview
The Kollmorgen S70302-NANANA is a digital servo amplifier designed for brushless servo motor applications requiring accurate torque, speed, and position regulation. Its S700 architecture supports 208–480 VAC three-phase power and provides onboard EtherCAT and CANopen communication. The standard configuration also includes an internal braking resistor and dual-channel Safe Torque Off.

S70302-NANANA
The 3 A RMS output rating at 400/480 VAC and 9 A short-duration peak capacity support industrial motion applications with variable acceleration demands. Actual motor compatibility depends on feedback type, motor electrical characteristics, control configuration, and the drive’s hardware and firmware revision.
Application Scenarios & Field Pitfalls
The S70302-NANANA is suitable for automated machinery requiring network-connected servo axes and coordinated motion control. Its onboard EtherCAT and CANopen interfaces can reduce the need for a separate fieldbus expansion card. However, replacing an installed drive requires checking the original network configuration, motor feedback, braking arrangement, and safety circuit.
Potential application areas
- Packaging and material-handling machinery with servo-driven positioning axes.
- Automated assembly equipment requiring coordinated motor movement.
- CNC and production machinery using brushless AC servo motors.
- Multi-axis systems communicating through EtherCAT or CANopen.
Engineer checks before replacement
- Verify the supply voltage and current rating. The drive supports 208–480 VAC three-phase input, but its continuous output-current rating changes with supply voltage. Confirm the actual plant supply and motor load.
- Check the communication architecture. EtherCAT and CANopen are onboard in the standard configuration. Verify which protocol the machine controller uses, along with node addressing and configuration data.
- Confirm feedback compatibility. The S700 family supports several feedback systems, including resolver, SFD3, HIPERFACE DSL, and encoder variants. The specific motor and hardware revision must be checked before connection.
- Validate STO wiring. Dual-channel STO is a safety function, not a general-purpose stop command. Check the machine’s safety design and perform the required validation after replacement.
- Inspect braking requirements. The internal brake resistor has a specified continuous rating of 50 W. Applications with higher regenerative energy may require an appropriately selected external resistor.
Related Products
These Kollmorgen models are useful comparisons within the S700 drive family. Their current ratings and optional configurations differ, so they are not automatic replacements.
- S70102-NANANA — Lower-current servo amplifier with 1.5 A output at 400/480 VAC. Suitable for smaller servo axes when motor requirements permit.
- S70602-NANANA — Higher-capacity drive, rated at 6 A output at 400/480 VAC. Consider for larger motor loads after checking supply and motor sizing.
- S71202-NANANA — 12 A-class amplifier at 400/480 VAC. Intended for higher-current servo applications; its power and braking requirements differ.
- S72402-NANANA — 24 A-class servo amplifier at 400/480 VAC. Used for substantially higher-current axes and requires a separate system-level compatibility review.
- S70302-NAF2NA — S70302 configuration with the F2 controlled-fan option in slot 2. Check the physical option arrangement and thermal requirements before substitution.
- -NANAF2 — configuration with the F2 option in slot 3. The option-slot location differs from the preceding model and must match the intended hardware configuration.
- S70602-NANANA — Higher-current counterpart with the same standard feature family. It may be relevant when reviewing a larger drive requirement, but is not a rating-equivalent substitute.
Procurement recommendation: Request the full nameplate photograph and confirm hardware revision, firmware version, and installed expansion cards. For a direct replacement, compare the complete order code rather than matching only the base model. The OEM manual documents several option-slot configurations that can change the delivered hardware.
