Product Description:
The S7480A-NANA-S4 is a servo drive manufactured by Kollmorgen and delivered within the S700 Servo Drives series. As an axis controller, it regulates the current and voltage supplied to brushless servo motors, enabling precise speed and torque loops in automated machinery such as packaging lines, pick-and-place stations, and gantry modules. The unit operates as the power interface between the host motion controller and the motor windings, providing rapid current modulation while integrating functional safety for modern production equipment.
Electrically, the drive accepts a three-phase input from 208 to 480 V, letting it connect to a wide range of industrial power systems without external transformers. The supply can deliver up to 35 kVA, which supports a continuous motor phase current of 48 Arms and short-term surges to 96 Arms during acceleration events. Its internal IGBTs switch at 8 kHz, producing a near-sinusoidal output with a form factor of 1.01. EtherCAT and CANopen interfaces are provided on the motherboard, so no expansion card is required. Functional safety is built in through the Safety 2-2 (S4) card, and a dual-channel STO removes torque-producing energy when commanded. At idle, the electronics draw 24 W, and mechanical relays are absent, which helps keep steady-state energy loss low.
Heat is removed through the cold plate base, and its thermal path is rated at 0.055 K/W, which helps keep temperature rise predictable at full load. During operation, the inverter dissipates 635 W, and the cold plate center must remain below 75 °C. The residual voltage drop from the DC link to the motor is only 6 V, improving efficiency when operating near field-weakening limits. Coated printed-circuit boards and the cold plate design are standard features. The installation footprint measures 190 mm wide, 244 mm deep, and 386 mm high, while the overall mass is 10.4 kg, permitting vertical mounting without reinforcement. Under worst-case load, the drive emits no more than 62 dB(A), keeping cabinet sound pressure at a manageable level.
