Fanuc Motor Safety Procedures and Tips

We have people ask about best practices for working with Fanuc motors all the time, so here are some Fanuc Motor Safety Procedures and Tips. For more info you can check out  all of our Fanuc products or email us at sales@mroelectric.com.
When working with servo motors:
•NEVER pick up or carry the motor by the cables or the shaft. (Always carry by the frame.) Use a crane or lift to move the motor when necessary.
•NEVER drop or subject the motor to impact. The servo motor is a precision device.
•NEVER set heavy or sharp objects on the motor or cables. Do not step or sit on the motor or cables.
•NEVER use a metal hammer on any part of the motor. If it is absolutely necessary to use a hammer, use a plastic hammer.
Keep the motor properly secured and away from the edge of the work area when servicing the motor, as a dropped motor could

cause personal injury or destroy the motor

Basic Motor Safety, Procedures, and Best Practices
• Be safely dressed when handling a motor.
Wear safety shoes and gloves. Avoid loose clothing which can get caught
on the motor. Be careful not to let hair get caught in the rotary section of the motor. Do not handle the motor with wet hands.
• Shut off the power before working on a motor. Wait at least 5 minutes after the motor is shut off before touching any
power terminals.
• Always use the correct cables. Centroid cables are shown in the motor compatibility table. Wiring diagrams and pin outs
for motors are provided in Appendix B.
• Ensure that the motor and motor related components are mounted securely. Ensure that the base or frame to which the
motor is mounted to is strong enough.
• Do not touch the rotary section of the motor when it is running unless instructed to.
• When attaching a component having inertia to the motor, ensure any imbalance between the motor and component is minimized.
• Be sure to attach a key to a motor with a keyed shaft.
• Use the motor in appropriate environmental conditions. Do not store flammables in close proximity to the motor. When
not in use, store the motor in a dry location between 0° to 40° C.
• Do not remove the nameplate from a motor

Unidrive Security Code Basics

For some new User’s of Unidrives, the parameter security system is sometimes found to be a rather mysterious subject.  This article will attempt to unveil those mysteries with some help to explain the Control Techniques Unidrive Security Code Basics.

Security Basics

Without entering the basic security code, 149, you will only be able to view Menu 0 parameters.   The “as shipped” security code for the Unidrive is 149. To enter this code you would maneuver to #00.00 and enter 149.   Once this security code is entered, you will be able to maneuver throughout the Unidrive menu structure freely to view parameters.

After a security code is entered, it will remain in effect until power is removed from the drive or if you wish to re-establish this security, you can set  #XX.00 to 2000.  (where  XX means  “any menu”  )

The User Security Code parameter is #11.30.  The “as shipped” value in this parameter is 149.

For more info you can check our webpage here, or email sales@mroelectric.com or call 1-800-691-8511.

If you find that you cannot change R/W (Read/Write) parameters (including those in Menu 0), someone has most likely assigned their own security code.

User Security Code Assignment

User’s can assign their own 3 digit security code within the range of 1-255 by placing it into #11.30 (writing over the 149) and performing a STORE.1 Note that this does not eliminate or change the “Normal security” code number – 149.

From this point forth, access to parameters will require that code to be placed into #XX.00.  At this point you only have access to Menu O. After this code is entered, you must still enter the normal access code (149) to gain access beyond Menu 0 parameters ( full access).

These security methods do not affect serial communications.  Security affects only access to parameters through the keypad on the front of the Drive.

Forgotten Security Codes

People often forget their security codes.   A User assigned security code is not visible at #11.30 via the serial port (you would still see 149).  To retrieve the forgotten security code,  you must go in through the “back door” .

“The Back Door”

To obtain the forgotten security code, you can DEPRESS and HOLD the MODE key, LEFT ARROW key and either UP or DOWN Arrow key then APPLY POWER to the drive.   The User security code number should appear on the data display at #00.00. Normally, the drive displays the contents of parameter #0.10 upon application of power therefore the User security code may not immediately appear.  You must use maneuver to #00.00 to see the forgotten security code then enter it (hit the mode button twice).

Security Bypass 

During initial start-up of the drive, having to enter the security code after each power-up can become a nuisance and slow down the start-up process.   To bypass or eliminate the need to enter a security code, one can accomplish this by placing a 0 into parameter #11.30 and performing a Store.
If this bypass is done to speed up the start-up process, you should remember to re-assign the 149 default to #11.30 (and Store) before leaving the job site. Otherwise, the drive will have no parameter access security.
Note: Defaulting the drive parameters (using 1244 or 1254) does not reset the User security code.  A previously assigned code by the User will remain in effect even after defaulting parameters.

Additional information     

Parameter 0.49 Security Status
Coding:  RO, U Range:  0 to 1000
This parameter indicates the current status of the drive parameter security system. Each digit indicates a particular aspect of security as follows:-

Units digit:  0 = Standard security has been unlocked    1 = Standard security is still set

Tens digit:                0 = User security has been unlocked or is not active    1 = User security is active preventing RW access

Hundreds digit: 1 = Parameter 11.30 not equal to 149*

Thousands digit: 1 = Parameter 11.30 equal to zero*

* The value of 11.30 is the last value written by the user. Parameter 11.30 always appears as 149 when first accessed by the keypad to hide the real value last written by the user. If 11.30=149 then user security is cleared. If 11.30=0 then user security and security preventing access outside menu 0 is cleared.

Note: – In contrast to all the other parameters in menu 0, this parameter does not exist in any other menu.

The Modicon 984 Family of PLCs

The Modicon 984 family of PLCs  bring the high performance,
application flexibility, and programming compatibility of the 984 family to the small
controller market. As a controller in the 984 family, Compacts implement a common
instruction set for developing user logic, standard Modbus communication
functionality, and optional Modbus Plus communication capabilities.
The Compact Controllers share the following 984 processing architecture features:
– A memory section that stores user logic, state RAM, and system overhead in
battery-backed CMOS RAM and holds the system’s Executive firmware in
nonvolatile PROM or FLASH RAM
– A CPU section that solves the user logic program based on the current input
values in state RAM, then updates the output values in state RAM
– An I/O processing section that directs the flow of signals from input modules to
state RAM and provides a path over which output signals from the CPU’s logic
solve are sent to the output modules
– A communications section that provides one or more port interfaces. These
interfaces allow the controller to communicate with programming panels, host
computers, hand-held diagnostic tools and other master devices, as well as with
additional controllers and other nodes on a Modbus (or Modbus Plus) network
 
This architectural consistency allows the The Modicon 984 Family of PLCs to achieve machine compatibility with the other controllers in the family. This allows sequences of user logic created on a mid-range or high performance controller, such as a 984B or a
984-685 Controller,-to be relocated to a Compact. It also assures that user logic
generated for this small controller is upwardly compatible to larger 984(s). Thus, a
Compact can be easily integrated into a multi-controller network.
