Replacement of the Lexium 62 ILM Integrated Servo Drive
Before beginning the replacement of specific components, read thoroughly the section Replacing Components and Cables for important safety information and general instructions.
How to Replace the Lexium 62 ILM
The Lexium 62 ILM is heavy relative to its size. While replacing the component, its mass can cause injuries and/or damage.

ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH |
|
oDisconnect all power from all equipment including connected devices prior to removing any covers or doors, or installing or removing any accessories, hardware, cables, or wires. oPlace a "Do Not Turn On" or equivalent hazard label on all power switches and lock them in the non-energized position. oWait 15 minutes to allow the residual energy of the DC bus capacitors to discharge. oMeasure the voltage on the DC bus with a properly rated voltage sensing device and verify that the voltage is less than 42.4 Vdc. oDo not assume that the DC bus is voltage-free when the DC bus LED is off. oBlock the motor shaft to prevent rotation prior to performing any type of work on the drive system. oDo not create a short-circuit across the DC bus terminals or the DC bus capacitors. oReplace and secure all covers, accessories, hardware, cables, and wires and confirm that a proper ground connection exists before applying power to the unit. oUse only the specified voltage when operating this equipment and any associated products. |

|
HEAVY, FALLING COMPONENTS |
|
oUse a a suitable crane or other suitable lifting gear for mounting the component if this is required by the weight of the component. oUse the necessary personal protective equipment (for example, protective shoes, protective glasses and protective gloves). oMount the component so that it cannot come loose (use of securing screws with appropriate tightening torque), especially in cases of fast acceleration or continuous vibration. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
Pay attention to the ESD protection measures to avoid damages caused by electrostatic discharge.
|
|
|
ELECTROSTATIC DISCHARGE |
|
oUse the original or similar packaging to send back components. oComponents must be packaged in ESD packaging/film. |
|
Failure to follow these instructions can result in injury or equipment damage. |
The Lexium 62 ILM is composed of an integrated drive/motor combination, and is considered as one, inseparable component. When replacing the Lexium 62 ILM, the entire drive/motor combination must be replaced.

NOTICE |
|
IMPROPER REPLACEMENT OR OPENING OF THE COMPONENTS |
|
oDo not open the components to put it into operation or replace it. oIn addition to the information and instructions found in this present document, you must observe the information and instructions of the original machine builder. |
|
Failure to follow these instructions can result in equipment damage. |
Disconnect all connection cables on the Lexium 62 ILM.
NOTE: Be sure that the cables clearly indicate their connections before disconnecting.
The replacement of the Lexium 62 ILM may have an impact on positioning or other parameters relative to the machine application. For example, the application may employ techniques, such as indirect distance measuring, that may be lost as a result of the component replacement, and may therefore need to be recalibrated.

UNINTENDED EQUIPMENT OPERATION |
|
Be sure to consult the documentation of the original machine builder before attempting to replace the component. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
There are sensitive precision parts involved in the proper functioning of the Lexium 62 ILM. Therefore, care must be taken during the replacement of the component to avoid damage and disfunction.

NOTICE |
|
MECHANICAL FORCE TO THE ENCODER SYSTEM |
|
oPrevent impacts on the motor shaft when removing and attaching couplings to the motor shaft, as this could damage the encoder. oUse appropriate tools, such as an extractor. oAvoid mechanical damage to the coating of the motor housing. |
|
Failure to follow these instructions can result in equipment damage. |
