Kollmorgen S7120S-NANANA — S700 Series Digital Servo Drive (Forced-Air Cooled)

The Kollmorgen S7120S-NANANA is a high-performance digital servo drive from the S700 series, rated 12 A continuous (24/30 A peak) at 208–480 VAC, 3-phase, 50/60 Hz (approx. 9 kVA, S1). Featuring forced-air cooling, this larger-frame drive delivers sustained high power in compact panel space — the right choice for high-dynamics, high-throughput industrial axes.

The "NANANA" US order code denotes the standard configuration: CANopen and EtherCAT onboard, internal brake resistor, and single-channel STO safety — with no optional add-on boards. This drive suits packaging, printing, converting and material-handling machinery, including multi-axis systems with shared DC bus.

Your Benefits at a Glance

• 12 A continuous / 24–30 A peak — sustained high output for heavy-duty axes
• Forced-air cooling — high continuous power density in a compact frame
• CANopen + EtherCAT onboard — fieldbus connectivity included as standard, no add-on card needed
• Internal brake resistor — simplifies installation in typical servo applications
• Single-channel STO — safety torque off for simplified machine safety integration
• Ultra-fast current loop (0.5 µs) — high-dynamics, low-latency control
• Resolver & encoder feedback — wide motor compatibility
• Wide supply range — 208–480 VAC, 3-phase, 50/60 Hz; max. DC bus 900 VDC
• Proven S700 platform — trusted worldwide in machine automation

Key Features

Forced-Air Cooling Design The S7120S variant uses forced-air cooling to sustain high continuous output without derating, delivering the power of larger drives in a compact S700 frame — ideal for thermally demanding, high-throughput applications.

Standard Connectivity The S7120S-NANANA includes CANopen and EtherCAT onboard as standard — a clean, cost-effective way to integrate into modern motion networks without fieldbus expansion cards.

Safety & Protection Single-channel STO (Safe Torque Off) is built in as standard, supporting simplified machine safety concepts. Overvoltage, overcurrent and thermal protection keep the drive reliable in industrial environments.

Flexible Feedback & Power Resolver or encoder feedback covers a broad range of Kollmorgen motors; 208–480 VAC 3-phase input (max. DC bus 900 VDC) fits global machine platforms and common-bus configurations.
