Instructions:

  1. Make sure the jumpers on the new spindle PCB match the jumpers on your old spindle PCB.
  2. Remove the software chips from the old spindle PCB and install them onto the new spindle PCB.
  3. If possible, remove the NVRAM chip from the old spindle PCB and install it onto the new spindle PCB. This way you will not have to reprogram the chip as the new spindle will have the same instructions as the previous one.

It is very important to follow the manual and make sure that the chips and cards you are moving around are installed correctly. For instance, if you were to incorrectly install the software chips, not only would the display not show anything, you are leaving open the possibilities for a short and causing yourself even more trouble.

Diagnosing your FANUC Current Alarm

If you are getting a high current alarm on your FANUC motor, it is going to be caused by either the motor itself, the drive, or a cable. To begin the process of figuring out which alarm you are receiving you must disconnect the leads from the motor. Try powering it up and look to see if the alarm LED is lit. Fanuc alarms include the HC LED, alarm 8/9/A/B for Servo motors, and alarm 12 for Spindle motors.

  • If you no longer are seeing an alarm, the motor is most likely bad.
  • If you have powered the motor and are receiving the alarm, the issue is most likely with the drive.

Because you have disconnected the leads from the motor, you are able to use an ohm meter/megger to monitor the power levels of the cable and motor, and make sure they are working as intended. Using a megger will help you decide if your motor is grounded correctly where an ohm reader will let you know if your motor has shorted.

Using your ohm meter check for shorts both leg-to-leg and leg-to-ground on each of the legs. The leg-to-leg readings should be consistently low between every leg while the leg-to-ground readings will stay open. The megger is used to check between the leg and ground to see if the problem could be with the terminal box on the motor or any cables connected to it.

Maintaining Automation Machine Tools

Properly maintaining automation machine tools and machine parts (such as Control Techniques Unidrives found here) is the only way to avoid issues from a performance and durability perspective. Whether it’s an attachment, cleaning or routine check-up, keeping machinery tools up-to-date is imperative. Monsterous losses could very well occur from a business and production standpoint if maintenance is not prioritized, which nobody wants to run into.

Machine Tools’ Lubrication:
 Lubrication is one of the most important things to keep in mind when it comes to any automation machines. Generally, regularly inspecting lubrication levels is a great place to start. If you notice decreased lubrication levels throughout a period of time, be sure to schedule a weekly check-in and carefully monitor. Regularly protecting machines’ motors, including oiling and greasing of their moving parts, cannot be avoided.
Sharpen Key Parts

When concerning machine tools that feature components engineered for cutting, slicing, or chopping, ensuring their parts maintain their sharpness is a must. Consult with a specialist to determine if the machines’ parts are in proper condition, and also be sure that their parts are sharpened properly also.

Verify alignment specifications

Another strategy to maintain factory automation tools and parts (such as the Modicon Quantum CPU 140CPU43412A) is to ensure you’re aware of the appropriate verification of alignment specifications. Product or component misalignment may be detrimental to a machine’s performance. By performing a handful of test jobs to check the tools’ alignment, you’ll be able to adjust accordingly.

Examine the cleanliness

Ensure all machine tools are cleaned daily or weekly, depending on the user guides’ instructions. Machines often collect a large amount of dirt and filth when operated, which may result in long-term issues if not tended to appropriately.

Understand Correct Power Mode 

By routinely inspecting the working mode of machines and setting them to the appropriate power mode, issues can be avoided such as overworking a machine or running a machine too slowly, which could cause debris. Refer to the machine’s operating manual to understand appropriate power modes associated with specific machines.

How to maintain a PLC (Programmable Logic Controller)

Updated: June 2024

Proper maintenance of Programmable Logic Controllers (PLCs) is crucial to ensuring they continue to function efficiently and reliably. Routine PLC maintenance involves tasks such as checking for wear and tear, replacing defective components, and consistently updating the software. This proactive approach not only extends the lifespan of PLCs but also helps in avoiding unexpected downtimes and costly repairs. Additionally, maintaining PLCs plays a key role in predictive maintenance, leveraging data and analytics to foresee potential equipment failures and schedule timely interventions. By adhering to a consistent maintenance routine, industries can enhance their operational efficiency and safeguard their investments in automation technology.

Why is PLC Maintenance Important?

PLCs (programmable logic controllers) are such an integral part of the automation world, and in turn a major contributor to the industrial market. Downtime can be incredibly costly, and finding parts for legacy units can be difficult and time consuming. (MRO Electric sells many legacy and discontinued automation components, from top brands) Therefore, properly maintaining your PLC can avoid unnecessary headaches and get the most life out of your units.

Pre-Maintenance Checklist

Before starting preventative maintenance on your PLC, make sure to do the following:

  1. Back up your PLC program prior to getting your hands dirty (it’s also a good idea to always keep a master copy of operating programs on hand).
  2. Follow proper lockout/tagout procedures.
  3. Remove power from the system. Power should always be off and unplugged during maintenance.
  4. Audit all parts in use.

PLC Maintenance Procedures

This is a good guidebook to use when performing preventive PLC maintenance:

  1. Check environmental factors / operating conditions. Humidity, temperature and other factors play an important role in the longevity and proper operation of your components. Be sure that these factors are consistently within the range of your PLCs optimal operating conditions.
  2. Clear debris, dust, and buildup from your units. A clean working environment for your PLC is a great way to prevent downtime. Also, dust getting to the circuit boards could cause a catastrophic short circuit.
  3. Clean or replace all filters installed in enclosures. This allows your PLC to get the maximum airflow and ensures consistency.
  4. Check all your connections for a tight fit, especially I/O modules. This is a very simple way to make sure everything is working smoothly. Also, a loose connection may cause lasting damage to your components.
  5. Inspect I/O devices for proper adjustments.
  6. Check LED battery indicators on the RAM memory module in the CPU. If the OK LED is on or flashing, replace the battery ASAP.

Other Things to Keep in Mind

  1. Calibrate circuit cards with process control analogs every 6 months.
  2. Service devices such as sensors every month.
  3. Never place other pieces of equipment that produce lots of noise or heat close to your PLC.

How to maintain a PLC (Programmable Logic Controller)

As many of us know, PLCs (programmable logic controllers) are staples in the factory automation world. In order to have them running optimally and as efficiently as possible, routine maintenance is imperative. Generally, manufacturers produce PLCs to endure strenuous, unsterilized environments. By adhering to an adequate maintenance schedule, PLCs operating timeframe can be lengthened.

Protect your PLC

Always be on the lookout for corrosive and conductive contaminants that have the potential to become a detriment to a PLCs’ components. By completing visual inspections for black dust and blowing airborne particles from the PLC’s vicinity, you are lowering the likelihood of contamination.

Is power flowing?

A PLC will not operate correctly without adequate power. To avoid any operation bugs, remain vigilant of any surges or shorts.

Calibrate Analog Components

Always refer to the preventative maintenance schedule for any analog input device. Analog inputs need to be cleaned regularly and calibrated as accurately as possible.

Take EMI into consideration

EMI (electromagnetic interference) is known to cause horrible issues for PLCs without clearly indicating what the specific issue is or how to go about fixing it. To remain ahead of the game, many perform an audit of the local wiring to pinpoint potential EMI sources before they interfere with the operation of your PLC. Lower-level components and high-current wires often interfere with each other, which wiring designs must take into consideration.

Additional PLC Maintenance Tips

By creating a PLC maintenance checklist and adhering to it strictly, operating errors can likely be avoided. The space between the PLC and the machine it’s controlling should be minimal.
