Product Description:

The S74802-PBNANA servo controller is manufactured by Kollmorgen within the S700 Servo Drives series. As an S700 servo drive, it is installed between the mains supply and a motor to modulate current, velocity, and position for automated machinery. The unit performs this role while supporting EtherCAT and CANopen communication, allowing direct coordination with PLCs and motion controllers used in assembly lines, packaging machines, and material-handling systems. This arrangement lets the drive respond directly to machine commands while maintaining controlled motor operation.

The drive accepts three-phase input from 208 to 480 V and delivers a continuous output of 48 Arms, with transient excursions up to 96 Arms to cover acceleration surges. Its input side can draw up to 35 kVA, and the internal converter sustains a DC bus that may reach 900 VDC. A current form factor of 1.01 keeps waveforms nearly sinusoidal, while a residual voltage drop of 6 V limits internal heating. Dynamic braking energy can be shunted through a 15 Ω external resistor, and the switch cycle limit is 30 operations per hour. The housing measures 190 mm in width, 386 mm in height, and 244 mm in depth without connectors, and it emits 62 dB(A) at full load. No expansion card is necessary because EtherCAT and CANopen are onboard, and the electronics use standard PCBs.

At 480 V, the built-in brake chopper can dissipate 8 kW of mechanical energy, and conduction losses remain at 685 W when the drive supplies its rated current. The enclosure weighs 13 kg, which supports panel mounting while providing enough mass for heat spreading. For safety integration, the unit offers dual-channel STO, allowing control systems to remove drive torque without external contactors. Standard PCBs support stable internal layout and consistent thermal performance during operation in enclosed panels.
