Product Description:

The S74802-PBF2-F2 is a servo drive produced by Kollmorgen for the S700 Servo Drives series. It is installed between the line supply and a matched motor, converting fixed-frequency power into regulated output that supports precise torque, speed, and position loops in automated lines, packaging equipment, and material-handling cells. Motion commands and diagnostic data move over the PROFIBUS DP fieldbus, allowing the drive to exchange operating information with higher-level control equipment.

The drive operates from a three-phase input range of 208 to 480 V and delivers a continuous phase current of 48 Arms with short-term bursts up to 96 Arms during acceleration or shock loading. Internally, it pulses the output bridge at 8 kHz, a switching frequency that balances dynamic response with thermal stress. Line utilization is rated at 35 kVA, and a residual DC link drop of 6 V helps maintain stable bus voltage during regeneration events. A fan controller expansion card supervises the controlled-fan cooling option that keeps semiconductor temperatures within limits. At idle, the unit dissipates 24 W, maximum acoustic emission is 62 dB(A), the unit is fitted with standard PCBs, and it tolerates ambient humidity up to 85% RH without condensation.

The enclosure carries an IP20 rating, so the drive is intended for mounting inside a closed panel with forced air exchange provided by the surrounding system. Functional safety is implemented through a dual-channel STO circuit that removes gate signals to the output stage when a stop request is asserted. Control logic and sensors draw from an auxiliary supply of 24 VDC. Overall dimensions are 505 mm high, 190 mm wide, and 285 mm deep, and the housing weighs 13 kg. A voltage-controlled fan fitted to the base plate moves air through internal channels, and airflow is not restricted by the IP20 open-slot design.
