Product Details

Yaskawa CACR-SR44BZ1SF-AC Servo Drive(Servopack)

Manufacturer:Yaskawa Electric

Product Series:CACR-SR Series Servopack Servo Drives

Product Type:AC Servo Amplifier/Driver

Core Functions and Features:

As a member of the Yaskawa CACR-SR series,the CACR-SR44BZ1SF’s main function is to provide precise power drive and control signals for AC servo motors to achieve high-performance motion control.

Power and Voltage:

Specific to the CACR-SR44BZ1SF model,the”44″usually indicates the power level of the motor it is adapted to.According to Yaskawa’s naming convention,”44″usually corresponds to a motor drive with a power level of 4.4kW(kilowatts),or in some older series,it may refer to input current or KVA.

The input voltage is usually three-phase 200V or 230V level.

Control Mode:

Speed Control:Precisely control the speed of the servo motor.This is usually the main function of the CACR-SR series.

Position Control:Precisely position the motor shaft through external pulse commands or analog commands.

Torque Control:Control the torque output by the servo motor.

Compatible Motors:

Usually used with Yaskawa’s SGM series AC servo motors,such as the early SGM-M,SGM-F,SGM-S series motors.

Feedback Type:

Absolute Encoder:The”BZ”in”BZ1SF”refers to the support of motor feedback with absolute encoders.Absolute encoders can still maintain position information after the power is turned off,without the need to perform origin return every time the power is turned on,which improves efficiency and reliability.

Input/Output Interface:

Provides digital and analog input and output interfaces for receiving external control instructions(such as pulse trains,analog voltages),output status signals,and alarm signals.

It has protection functions such as overcurrent,overvoltage,undervoltage,overload,encoder failure,etc.

Design features:

Compact design:At that time,the series was known for its compact size and simple wiring,which helped save space in the control cabinet.

High reliability:It follows Yaskawa’s strict industrial standard design to ensure stable operation in various industrial environments.

Fast response:It has high precision and fast response capabilities to meet the needs of precision motion control.

Product Overview:

Brothers,the Yaskawa CACR-SR44BZ1SF you are asking about is a veteran”go-getter”in the Yaskawa servo system-the CACR-SR series servo drive.You can think of it as the”brain”that”gives orders”to the servo motor,and this”brain”is very flexible and can accurately control the motor’s speed,position and output torque.

This model,especially the”BZ”in the”BZ1SF”,means that it can connect to motors with absolute encoders.What are the benefits?That is,when the equipment is powered off and then turned on again,the motor does not need to find the origin again,and it directly knows where it is,which is trouble-free and efficient!

In the past years,this CACR-SR series has been widely used in various machines that require high-precision motion,such as those CNC machine tools with swords and swords,flexible industrial robots,packaging production lines,printing machines,etc.,which are its main battlefields.Although Yaskawa now has a more advanced Sigma series,these old machines are still in service in the factory,so this CACR-SR44BZ1SF drive is quite popular as a spare part,which is the key to ensure the continued operation of old equipment!

Main features and advantages

As a Yaskawa CACR-SR series servo drive,Yaskawa CACR-SR44BZ1SF had the following significant features and advantages at the time:

High precision and fast response:It can achieve high-precision control of the servo motor speed,position and torque,and has fast dynamic response capabilities to meet the motion requirements of precision mechanical equipment.

Absolute encoder support:Supports connecting servo motors with absolute encoders,eliminating the need to perform origin return every time the power is turned on,simplifying equipment operation and improving production efficiency.

Compact design:Compared with the same period of products,the CACR-SR series is more compact in size,which helps save space in the control cabinet.

High reliability:Follows Yaskawa’s strict industrial design standards to ensure stability and long life in various industrial environments(such as vibration,temperature changes).

Multiple control modes:Provides multiple control modes of speed,position and torque,and users can flexibly choose according to application requirements.

Complete protection function:Built-in overcurrent,overvoltage,undervoltage,overload,encoder failure and other protection functions to ensure the safe operation of the servo system and controlled equipment.

Application field

Yaskawa CACR-SR44BZ1SF servo drive is widely used in industrial automation equipment and machinery that require precision motion control:

Selection Guide/Purchase Recommendation

Brothers,if you are looking for or replacing the Yaskawa CACR-SR44BZ1SF servo drive for your equipment,I have to remind you that this is a”veteran”and you need to pay special attention when purchasing:

Product Life Cycle:Yaskawa CACR-SR series servo drives have been discontinued or are at the end of their life cycle.This means that the original Yaskawa factory usually no longer produces this brand new product,and it is difficult to buy it directly from the original factory.

Choose a reliable source of supply:For this discontinued spare part,you usually need to obtain it from the following channels:

New Old Stock(NOS)/New Surplus:Brand new but stocked for many years.This is the best choice,but it is extremely rare and expensive.

Professional Refurbished Parts:Professional industrial automation spare parts suppliers(such as Shenzhen Changxin)repair,clean,replace aging parts,and undergo rigorous functional testing to provide quality assurance.This is currently the most common and reliable procurement method.

Disassembled/second-hand parts:Unclear source,no test report,no warranty.Extremely high risk,not recommended for critical applications.

Accurately check the full model number:Be sure to provide the full model number CACR-SR44BZ1SF on the old drive.Yaskawa’s model coding is very detailed,and any difference in letters or numbers may cause compatibility issues.

Confirm compatible motors:CACR-SR44BZ1SF needs to be used with Yaskawa servo motors of specific power and encoder types(such as certain models of the SGM series).When replacing the drive,it is best to provide the full model number of the motor to confirm compatibility.

Warranty and technical support:Good suppliers will provide a clear warranty period for discontinued products(usually 6 months to 1 year).At the same time,given the professionalism and complexity of servo systems,suppliers who can provide technical support(such as installation issues,parameter setting suggestions)are particularly important.

Logistics and timeliness:If your production line is down due to a drive failure,fast delivery capabilities are essential.Choose a supplier who can provide emergency shipments and reliable logistics services.
