Product Description:
The S71201-SENA-NA-0X9 is a servo drive from Kollmorgen in the S700 Servo Drives series. It regulates torque, speed, and position of matched servo motors in automated machinery by converting three-phase mains power into controlled DC and pulse-width-modulated output. The unit sits between the plant supply and the motor, allowing the controller to issue motion commands that are carried out with stable electrical regulation. Integrated fieldbus connectivity lets the drive exchange operating data with the control system without requiring a separate communication module. Because the drive closes the current, speed, and position loops locally, the upstream controller can focus on machine sequencing rather than power conversion.
Electrically, the drive accepts a line voltage range of 208...480 V, draws a rated input apparent power of 9 kVA, and delivers a continuous output current of 12 Arms to the motor terminals. Internally, it supports a maximum DC-bus potential of 900 VDC, and the power stage switches at 8 kHz to balance response and heat generation. A minimum motor inductance of 2.7 mH is required when operating on 480 V, which helps maintain stable current control with compatible motors. EtherCAT and CANopen are available on the base unit, and the drive includes a single-channel STO function that removes torque without shutting off mains power. This arrangement supports direct integration into automated motion systems that rely on networked command and feedback exchange.
At the rated operating point, the housing releases 160 W of heat, so cabinet ventilation must move enough air to keep internal temperatures under control while noise remains limited to 65 dB(A). The control electronics use an auxiliary 24 VDC supply, and the integrated brake transistor can sink up to 2 A for holding actuators. The aluminum enclosure measures 70 mm wide, 243 mm deep, and 345 mm high, and it has a mass of 4.4 kg, which supports compact mounting next to neighboring axes. The compact frame also leaves room for cable routing and nearby components in shallow control cabinets. This layout is useful where several motion channels must be installed side by side.
