Product Details

443M-S S403AM-SE Product Description

The Kollmorgen S403AM-SE is a high-performance, energy-control servo drive engineered for demanding industrial environments where production efficiency, load stability, and energy conservation are mission-critical. As part of the proven ServoStar S400 series, the S403AM-SE delivers precise torque and velocity regulation, enabling smart production lines to minimize idle energy consumption, reduce thermal stress on drive components, and sustain consistent machine cycle rates across multi-axis automation cells.

Designed for seamless integration into modern industrial energy management architectures, the S403AM-SE supports coordinated operation with upstream PLCs, distributed I/O modules, and SCADA platforms, making it a cornerstone component for factories pursuing measurable reductions in energy cost per production unit.

In a fully integrated energy-aware automation cell, the Kollmorgen S403AM-SE operates as the primary motion energy controller, receiving setpoint commands from a Siemens S7-1200 PLC or Beckhoff CX2040 IPC via CANopen or EtherCAT fieldbus. The PLC continuously monitors production throughput targets and dynamically adjusts the servo drive's velocity profile to match real-time load demand — eliminating the energy waste associated with fixed-speed operation.

Power quality upstream is maintained by a Kollmorgen P70360 industrial power supply, which conditions incoming AC voltage and provides stable DC bus power to the S403AM-SE. When the connected Kollmorgen AKM52G servo motor decelerates or enters a braking phase, the S403AM-SE's regenerative braking circuit recovers kinetic energy back to the DC bus, reducing net energy draw from the grid and lowering heat dissipation within the control cabinet.

Real-time power consumption data is captured by a Janitza UMG 96RM-E power monitoring module installed on the same panel bus. This module feeds energy metrics — including active power, reactive power, and power factor — to the plant's SCADA system (such as Wonderware InTouch or Ignition), where energy KPIs are trended and alarmed against production benchmarks. Operators viewing the Kollmorgen WorkBench HMI software can visualize drive status, torque utilization, and thermal load in real time, enabling proactive intervention before efficiency losses compound.

On the I/O layer, a Beckhoff EL1008 digital input terminal and EL2008 digital output terminal relay machine-state signals — such as e-stop, axis-ready, and fault-clear — between the S403AM-SE and the broader automation network. A Kollmorgen SFD3 smart feedback device mounted on the motor shaft provides high-resolution position and temperature data back to the drive, enabling the S403AM-SE to apply adaptive current limiting when motor winding temperatures approach threshold, directly reducing thermal load and extending motor service life.

For multi-axis coordination in robotic or gantry applications, the S403AM-SE synchronizes with peer drives — such as the Kollmorgen S606AM-SE for higher-current axes — through the shared CANopen network, ensuring that axis motion profiles are phase-aligned and that peak current demands are staggered to flatten the facility's power demand curve.

Factory energy audits consistently identify servo drive systems as one of the top three contributors to controllable energy waste in discrete manufacturing. The Kollmorgen S403AM-SE addresses this directly through three core mechanisms: adaptive load following, regenerative energy recovery, and intelligent standby management.

Adaptive Load Following: The S403AM-SE continuously samples motor current and shaft velocity at high frequency. When production demand drops — such as during a conveyor idle period or a robotic arm hold position — the drive automatically reduces output power to the minimum required to maintain position lock. This eliminates the constant full-power draw that characterizes older, non-adaptive servo systems, and can reduce energy consumption during low-load intervals by 20–35% depending on duty cycle.

Regenerative Energy Recovery: During deceleration phases — common in pick-and-place, press-brake, and packaging applications — the S403AM-SE captures the motor's back-EMF and returns it to the DC bus. In high-cycle applications running 200+ cycles per minute, this regenerative contribution meaningfully offsets the drive's net energy consumption and reduces the thermal load on braking resistors, lowering cabinet cooling requirements and extending resistor service intervals.

Intelligent Standby Management: When the production line enters a scheduled pause or changeover, the S403AM-SE transitions to a low-power standby state under PLC command, disabling the output stage while retaining encoder position data. This eliminates the continuous switching losses that occur when a drive remains fully enabled at zero speed — a common source of unnecessary energy draw in 24/7 manufacturing environments.

Together, these capabilities allow plant engineers to demonstrate measurable energy savings per shift, support ISO 50001 energy management reporting, and reduce the total cost of ownership of the servo axis over its operational lifetime. With stock available for immediate dispatch and full pre-shipment functional testing completed on every unit, the S403AM-SE is ready to be integrated into new installations or deployed as a direct replacement for aging ServoStar S400 series drives.

Q1: What energy savings can I expect from deploying the Kollmorgen S403AM-SE on my production line?Actual savings depend on your application's duty cycle, load profile, and current drive technology. In typical discrete manufacturing environments with variable load cycles, customers report 15–35% reductions in servo axis energy consumption compared to older fixed-gain or non-regenerative drives. The S403AM-SE's adaptive load following and regenerative braking are the primary contributors to these gains.

Q2: Is the S403AM-SE compatible with my existing PLC and communication infrastructure?The S403AM-SE supports CANopen natively and is compatible with RS-232/485 for commissioning and parameter management. Optional communication cards enable PROFIBUS-DP and EtherCAT connectivity, making it interoperable with Siemens S7, Beckhoff TwinCAT, Mitsubishi MELSEC, and other major PLC platforms. Confirm your fieldbus topology before ordering to select the correct option card.

Q3: Can the S403AM-SE replace an existing ServoStar S400 series drive without mechanical or wiring changes?Yes. The S403AM-SE is a form-fit-function replacement within the ServoStar S400 family. Mounting dimensions, connector pinouts, and parameter file formats are compatible with earlier S400 variants. Motor tuning parameters can be imported from existing WorkBench project files, minimizing recommissioning time. Always verify firmware version compatibility before swapping drives in a live production environment.

Q4: What does the 12-month warranty cover, and what is the testing process before shipment?Every Kollmorgen S403AM-SE unit supplied by NANKMOS undergoes pre-shipment functional testing covering power-on self-test, output stage verification, feedback interface check, and communication port validation. The 12-Month Warranty covers manufacturing defects and component failures under normal operating conditions from the date of shipment. Warranty claims are processed through NANKMOS with replacement units dispatched from in-stock inventory to minimize your downtime exposure.
