Product Description:
Kollmorgen produces the S72401-NANANA-NA-FW3.75 as part of the S700 series digital servo amplifiers. It combines integrated short circuit defense with 130 % overload protection through solid-state elements and features a protective time-delay fuse rated at 30 A. The communication capabilities of the device allow usage of EtherCAT and CANopen along with RS232.
The S72401-NANANA-NA-FW3.75 controller offers dual-channel STO functionality and achieves SIL CL3 and PLe safety standards. It presents an overall width of 100 mm while operating through convection cooling without active fan components and comes with three expansion slots for any additional functionality. The S72401 controller enables use with different feedback devices consisting of resolvers, encoders and digital systems which include HIPERFACE/ROD/BiSS/EnDat while analog and digital feedback types can connect through the X1 and X2 points. It includes a built-in brake resistor while also maintains support for an external brake resistor connection at terminal X8. The S72401 controller exhibits variable peak voltage rise rates (dU/dt) which achieve 6.9 kV/μs at 480 V. The operation reliability requires that the drive resides within an enclosed and grounded cabinet for both advanced motion control and integrated safety features.
The S72401-NANANA-NA-FW3.75 controller drive maintains ongoing output current of 24 Arms and it provides temporary output current capability reaching 48 A for 5 sec then extending to 72 A for 2 sec. It runs on a 3-phase AC power between 208 to 480 V AC while accepting 10 percent variance in the specified voltages. The S72401 controller has minimal changing inductance values for motor across input voltage range, which begins at 0.7 mH for 208 V then extends to 1.7 mH at 480 V. Its output stage switching uses a predefined frequency of 8 kHz.
Frequently Asked Questions about S72401-NANANA-NA-FW3.75:
Q: Why does the S72401-NANANA-NA-FW3.75 include three expansion slots?
A: These slots support optional modules, enabling flexible integration of additional I/O, fieldbus interfaces, or encoder feedback modules for custom applications.
Q: What role does the switching frequency of 8 kHz play in the S72401-NANANA-NA-FW3.75’s output stage?
A: It minimizes audible noise and harmonics, ensuring smoother torque control and reduced EMI in precision servo systems.
Q: How does the built-in brake resistor help in the S72401-NANANA-NA-FW3.75?
A: It dissipates regenerative energy during deceleration, protecting the drive from overvoltage and ensuring stable stopping performance without needing an external resistor in light-duty cycles.
Q: What is the purpose of having support for multiple feedback types in the S72401 controller?
A: It allows compatibility with a wide range of motors and motion systems, simplifying retrofitting or mixed feedback setups within a single machine.
