Product Description:

The S70602-PBNANA servo drive is produced by Kollmorgen as part of the S700 Servo Drives series. In automated machinery, this drive controls synchronous or induction motors by converting three-phase mains power to a regulated DC bus and modulated output phases. By managing torque, speed, and position loops, it acts as the motion interface between the higher-level controller and the machine actuators. This allows the drive to support precise motion on indexing, transport, and positioning axes across a wide range of automated equipment. The compact housing and integrated fieldbus resources make the S70602-PBNANA a flexible axis amplifier for packaging lines, printing systems, and material-handling equipment.

The unit operates from a three-phase supply in a nominal range of 208 to 480 V, and internally the DC link can rise to 900 VDC under full regeneration. Continuous motor current is 6 Arms, while a peak current of 18 Arms per phase is available for 2 seconds to accelerate high-inertia loads before the control returns to rated limits. Power devices switch at 8 kHz, which helps smooth current ripple without excessive transistor losses. The drive draws 4.5 kVA at nameplate loading and accepts grid frequencies of 50 or 60 Hz. EtherCAT and CANopen are supported natively, so the expansion slot remains available for other options.

The housing is 70 mm wide, 243 mm deep, and 345 mm high, and the unit has a mass of 4.4 kg, allowing side-by-side cabinet mounting. Thermal design lets the enclosure dissipate input losses without auxiliary fans, and the circuit boards are treated for industrial duty. Safe Torque Off is implemented through a dual-channel STO circuit that disconnects the gate drives in less than a millisecond, eliminating residual motion energy. Two communication links are provided on 2 x 9-pin D-Sub connectors for PROFIBUS networks. After brief overload events, the drive automatically returns to nominal current to protect the power semiconductors.
