Product Description:
The S72401-NANANA-NA-FW3.75 is a Kollmorgen servo drive supplied under the S700 Servo Drives series. It includes onboard EtherCAT and CANopen communication, so no additional expansion card is required, and its single-channel STO circuit supports basic functional safety stops without external contactors. Standard printed circuit boards and a compact housing allow the unit to be installed near the motor it controls. In this position, the drive modulates three-phase mains power and delivers tightly regulated current for precision motion tasks across packaging, material-handling, and assembly lines.
The drive accepts line voltages from 208 to 480 V and draws up to 18 kVA of apparent power under full load. Continuous motor phase current is limited to 24 A RMS, while surge demands are handled by a peak output of 48 A RMS for two seconds, giving axis drives the additional torque needed for rapid acceleration. An internal 23-ohm brake resistor rated at 200 W absorbs regenerative energy during normal stopping. If the internal resistor approaches its thermal limit, energy is diverted to an external brake channel to protect the drive during further regeneration. Pulse-width modulation regulates the motor current and helps reduce ripple during operation.
The housing measures 100 mm wide, 243 mm deep, and 348 mm high, while its total mass is 5.5 kg, so cabinet mounting does not require heavy supports. Heat dissipation from the switching devices is rated at 330 W, and adequate airflow or liquid cooling must remove this heat to preserve component life. For emergency deceleration, the external brake circuit can dissipate up to 4 kW, substantially exceeding the capacity of the internal brake resistor. The shared DC link can reach 900 VDC, allowing multiple axes to operate from a common high-energy bus supply. The selected carrier frequency of 8 kHz balances acoustic noise and semiconductor losses during continuous operation.
