Rexroth HCS02.1E-W0054-A-03-NNNN IndraDrive C Integrated Single-Axis Servo Drive Controller

HCS02.1E-W0054-A-03-NNNN belongs to Rexroth IndraDrive C HCS02 compact servo drive family, an integrated design combining rectifier power supply, 

DC bus link and servo inverter in one single unit. It executes closed-loop torque, speed and position control for Rexroth IndraDyn synchronous servo motors and asynchronous 

spindle motors, receiving motion instructions from upper PLC or motion controller to realize high-precision positioning, speed regulation and tension control.

This model features built-in fan forced cooling design, supports common DC bus energy sharing for multi-axis system energy recovery and energy saving. It is compatible with multiple 

mainstream encoder feedback signals and industrial fieldbus communication modules, realizing seamless networking with automation host systems. Equipped with comprehensive hardware 

fault diagnosis and protection logic, it ensures stable operation under frequent acceleration/deceleration and heavy overload working conditions. Widely applied in CNC machine tools, 

packaging machinery, printing winding equipment and automated production lines, it serves as critical maintenance replacement spare part for equipment overhaul, axis fault repair 

and automation system retrofitting.
