Product Description:

The S7480A-PBF2-PA is a single-axis servo drive manufactured by Kollmorgen and included in the S700 Servo Drives series. As a digitally controlled amplifier, it interfaces between a plant’s AC supply and a synchronous or induction motor to regulate torque, speed, and position in automated machinery. The unit integrates motion control, fieldbus communication, and functional safety so compact drive cabinets can be used in packaging lines, material handling stations, and other high-performance motion tasks.

The drive accepts a three-phase input of 208 to 480 V, allowing installation on industrial mains used in many regions. Its power stage is designed for a continuous draw of 35 kVA, which suits equipment that requires up to 48 Arms of motor phase current. A PWM switching frequency of 8 kHz helps reduce motor acoustic noise while preserving current loop bandwidth. Command inputs are handled through a differential analog channel with an input resistance of 20 kΩ, and each sample is refreshed every 62.5 µs to support tight velocity loops. The ±10 V analog output can feed legacy position followers, and dual 9-pin SubD Profibus connectors provide networked parameter access. Dual-channel STO removes motor torque without contactors for Category 3 stops.

Thermal management uses a cold plate base that diverts losses directly to the machine frame, and a dedicated fan controller expansion card can regulate an external blower when required. The available peak current rises to 96 Arms for rapid indexing moves, and analog feedback leaves the unit with a resolution of 0.38 mV, which helps minimize quantization error during precision profiling. With coated PCBs and the cold plate plus coating option, the electronics tolerate humidity and airborne contaminants. The overall height is 386 mm, and the cold plate weighs 10.4 kg, which affects panel load calculations; the depth without connectors is 244 mm. When the fan is disabled, internal dissipation is limited to 24 W, which helps preserve cabinet temperature margins.
