S7120S-NAPMNA by Kollmorgen

The S7120S-NAPMNA drive represents a pinnacle of digital amplifier technology from Kollmorgen in the S700 Servo Drives series, designed for demanding industrial automation systems. This Product Type: S700 Servo Drive accepts three-phase input at Voltage Rating: 208...480V AC and delivers a continuous Rated Current: 12 Arms with a Nominal Power Output: 9 kVA rating. Engineered as a high-performance servo amplifier, it incorporates Expansion Card: No expansion card , EtherCAT&CANopen onboard for streamlined communication and diagnostics. The drive features an integrated RS232 port accessible via port X6 for service-level monitoring and configuration. Requiring a dedicated Voltage: 24V DC auxiliary supply, the unit maintains precise control electronics independent of the main power source.

Performance characteristics emphasize dynamic response and safety. With Option Detail: Extended Ipeak, the amplifier delivers peak output currents of 30 A for two seconds and 24 A for five seconds under transient loads. Its STO Capability: Dual channel STO function ensures functional safety integration, while onboard EtherCAT and CANopen interfaces facilitate seamless network communication. Forced airflow cooling via an internal blower requires mandatory vertical cabinet placement to maintain thermal stability. The drive’s internal dc bus maintains up to 900 V peak voltage, optimizing torque response and minimizing current ripple during rapid acceleration and deceleration phases.

Reliability and integration are reinforced by versatile connectivity and robust mechanical design. The drive’s solenoid valve interface, featuring a Valve Function: 3/2-way normally closed configuration, employs an Electrical Entry: DIN terminal and supports Pressure Range: 0.15 to 0.7 MPa pneumatic control, with a Response Time: 18 ms or less. Built for ambient temperatures from Temperature Range: -10°C to 50°C, it can be stored between -13°F and 131°F at up to 95% non-moist humidity. A Manual Override: Non-locking push type facilitates on-site maintenance without disassembly, while the Actuation: Internal pilot operated manifold mounting simplifies integration into compact control cabinets. Motor, brake, and auxiliary connections are clearly assigned to X9, X4, and X0 terminals, streamlining installation in packaging machines, robotic cells, and other automated processing equipment.
