Main Features and Advantages
2kW power with precision:Yaskawa CACR-HR20UB ServoPack delivers 2kW of steady power,making it ideal for medium-load tasks like driving conveyor belts in warehouses or rotating tables in machining centers.What sets it apart is its ability to maintain±0.1%speed stability even when load changes by 50%—critical for applications like bottle filling,where uneven speed causes overfilling or underfilling.
Fast response for dynamic tasks:With a 4kHz response frequency,CACR-HR20 reacts to control signals in milliseconds.In robotic pick-and-place operations,this means the arm can accelerate,decelerate,and stop sharply without overshooting,reducing cycle times by up to 15%compared to slower drives.
Rugged for tough environments:Built to withstand industrial rigors,Yaskawa CACR-HR20UB operates reliably in 0-55°C temperatures and resists vibration up to 5g.In metalworking shops—where coolant mist and dust are common—its sealed terminals prevent corrosion,extending service life to an average of 8+years in field tests.
Flexible integration:It plays well with Yaskawa’s SGMGH series 2kW motors,but also works with third-party motors via parameter tweaks.This flexibility shines during retrofits—an auto parts manufacturer recently upgraded their aging line by swapping in CACR-HR20,keeping existing motors and cutting upgrade costs by 30%.
Application Field
In automotive manufacturing,Yaskawa CACR-HR20UB ServoPack powers robotic welding arms,where its 2kW output and precise torque control ensure consistent weld penetration.The 4kHz response lets the arm adjust instantly to sheet metal thickness variations,reducing rework rates.It’s also used in chassis assembly lines,driving the rotation of worktables to position car frames for drilling—accuracy here prevents misaligned holes that would delay final assembly.
Logistics and material handling rely on CACR-HR20 for conveyor systems in distribution centers.It regulates belt speed to match upstream/downstream equipment,preventing bottlenecks.When paired with vision systems,it can even slow or stop sections to correct package misalignment,keeping sorting lines running smoothly during peak hours.
Plastic injection molding machines use Yaskawa CACR-HR20UB to control screw rotation,a critical step in melting and injecting plastic.Its torque control mode ensures consistent pressure on the molten plastic,reducing part defects like sink marks or flash—a major win for manufacturers of precision plastic components.

Installation and Maintenance
Pre-installation preparation:Mount Yaskawa CACR-HR20UB ServoPack on a DIN rail or panel with at least 100mm clearance above/below for airflow—overheating is the#1 cause of early failure.Check input voltage is 3-phase 200-240V;use a multimeter to confirm no voltage spikes.Connect motor and encoder cables to the correct terminals(color-coded in the manual)to avoid reversed rotation—swap two motor wires if the motor runs backward.
Maintenance recommendations:Inspect CACR-HR20 monthly for dust buildup;use compressed air to clean vents.Every 6 months,tighten terminal screws—vibration can loosen them,causing intermittent faults.Monitor the drive’s LED:green means all’s well,red indicates issues(check the manual’s fault code list—most are fixable via parameter resets).If the drive shuts down due to overload,let it cool 30 minutes before restarting;repeated overloads mean the drive is undersized for the task.
