Product Description:

The S72402-PBNANA is a Kollmorgen S700 Servo Drives series unit intended for closed-loop control of brushless and induction motors in industrial automation cells. It converts three-phase mains power into regulated output that matches real-time motion commands delivered over the factory network. EtherCAT and CANopen interfaces are built into the base hardware, so no expansion card is required for fieldbus connectivity. Dual-channel STO circuitry provides a certified hardware gate for immediate torque removal during safety stops.

The drive can supply a continuous output current of 24 Arms, and its input side accepts up to 18 kVA to cover dynamic acceleration peaks without derating. A mains window of 208 to 480 V lets the same model operate on common industrial supply systems. The power stage switches at 8 kHz during normal service, and a 16 kHz setting with reduced current capability is available when lower current ripple is required. When the axis decelerates, the built-in brake chopper can absorb up to 200 W of regenerative energy, which helps prevent DC-bus overvoltage. Internal logic limits commanded power cycling to 30 on-off events per hour to protect semiconductors. Additional losses amount to 20 W in a disabled state and 160 W at rated load, figures that are used for cabinet cooling calculations.

The mechanical package weighs 5.5 kg, measures 100 mm in width, and reaches 348 mm in height, with a depth of 243 mm that fits standard 300 mm control enclosures. Maximum audible emission is kept to 65 dB(A), which supports use in typical shop-floor conditions. A 23 Ω internal brake resistor works with the chopper circuit for occasional high-energy stops. Standard PCBs contribute to long-term serviceability, and the unit has factory-installed conformal coatings for pollution degree 2 environments. Thermal energy is removed by convection across the finned aluminum housing, and the STO function remains active regardless of the power state.
