Product Description:
The S74802-NANANA is a Kollmorgen servo amplifier supplied in the S700 Servo Drives series. It converts three-phase mains power into regulated output for brushless motors used in automated machinery. The hardware uses standard PCBs, sits in an IP20 enclosure for cabinet mounting, and measures 190 mm in width, 244 mm in depth, and 386 mm in height. These physical and protective features support motion axes that need accurate torque and speed regulation while keeping live parts touch-safe.
The drive supplies 48 Arms continuously and can surge to 96 Arms for short accelerations. It accepts line voltages from 208–480 V and uses an output stage clocked at 8 kHz to limit motor current ripple. At 480 V, the electronics dissipate 685 W of heat, while the disabled state drops that figure to 24 W to reduce standby cooling demand. An output current form factor of 1.01 helps keep motor heating predictable, and rated input power is 35 kVA. A voltage slew rate of 4.8 kV/µs and onboard EtherCAT plus CANopen, provided without an expansion card, support fast fieldbus updates and require suitable cable shielding.
Functional safety is provided by dual-channel STO, which removes drive energy to the motor without external contactors during emergency stops. Under dynamic load, the DC link sees a residual drop of only 6 V, helping sustain response when energy regenerates. Compatibility with low-inductance motors is supported by a minimum winding inductance of 0.88 mH at full voltage, and the chassis weighs 13 kg to help resist vibration in multi-axis frames. Maximum noise emission is limited to 62 dB(A), so the unit can be installed in accessible control cabinets without additional acoustic treatment.
