Product Description:

The S7480A-PBF2-S3 is a Kollmorgen servo drive in the S700 Servo Drives series. It regulates torque, speed, and position for matched rotary or linear motors by converting three-phase line power into precisely timed PWM output while tracking feedback and fault channels. This arrangement allows the drive to translate controller commands into stable motor response during dynamic moves. Kollmorgen classifies the unit as an S700 servo drive, and inside an automation cell it bridges the PLC and the motor while supporting integrated safety functions.

Electrically, the drive accepts line voltage from 208 to 480 V, allowing use on most low-voltage three-phase networks. It can draw up to 35 kVA and supplies a continuous phase current of 48 Arms, while its control loop permits peaks of 96 Arms for short acceleration bursts. At 480 V, the output stage produces a dv/dt of 4.8 kV/µs, so suitable motor-cable insulation is required. Kollmorgen specifies a minimum load inductance of 0.88 mH to limit ripple in the output current. A residual voltage drop of 6 V across the IGBTs is included in back-EMF calculations. Dual-channel STO disables torque without external relays, and the fan-controller expansion card can power auxiliary blowers when higher cabinet temperatures are expected.

The coldplate base supports mechanical mounting and thermal integration, and it adds 10.4 kg to the assembly while mating directly to a liquid-cooled panel. Installed dimensions reach 505 mm in height, 190 mm in width, and 285 mm in depth, so the enclosure must accommodate that footprint. Coldplate cooling is paired with coated PCBs to help resist condensation on the electronics. The drive width leaves room for adjacent modules, and the cooling plate helps manage heat generated by switching losses. This layout supports dense panel arrangements without requiring direct air cooling through the drive body.
