Product Description:

The S70602-PBNAS2 is a servo drive produced by Kollmorgen as part of the S700 Servo Drives series. In an automation cell, the drive interfaces between a motion controller and a synchronous motor, converting incoming three-phase mains power into controlled output for precise machine positioning. By embedding feedback decoding and safety circuitry, the unit supplies regulated current loops and implements safe torque off so actuators can be energized or de-energized under deterministic control.

Its electrical envelope begins with a mains voltage window of 208 to 480 V, allowing the same hardware to be wired on low- or high-voltage factory bus systems. Under nominal operating conditions, the drive draws 4.5 kVA and delivers a continuous phase current of 6 Arms, which suits medium-frame servo motors in packaging and assembly lines. For rapid acceleration, the current can rise to 18 Arms for two seconds, supplying additional electromagnetic torque without exceeding silicon limits. Internally, the IGBT bridge is modulated at 8 kHz, a switching frequency that balances dynamic response with reduced motor acoustic noise. When higher burst duty is needed, the unit can still sustain 12 Arms for five seconds, and dual-channel STO prevents torque generation as soon as either safety path is interrupted.

Thermal behavior includes idle loss of 20 W and 100 W at nominal load, while a built-in 33 ohm brake resistor dissipates regenerated energy. Up to 75 W of brake power can be accepted without an external module. Communication is handled by EtherCAT and CANopen on the base electronics together with the PROFIBUS DP interface listed for this model, and no expansion card is needed because the option detail calls for standard PCBs. The chassis is rated Safety 2-2 for functional integrity, measures 70 mm wide, 243 mm deep, and 345 mm high, and has an installed mass of 4.4 kg.
