Once your motor is received, it is thoroughly cleaned and reconditioned. Our trained technicians disassemble, inspect, and troubleshoot each individual motor component. After each non-functioning component is replaced or repaired, we test motor function fault, brake, encoder, and thermistors. We then commission the motor using one of our drives, testing it in both forward and reverse for at least an hour.

MRO Electric also stocks both new and refurbished FANUC motors with rush shipping options available. If you require a working motor immediately, you can take advantage of our core exchange policy to return your non-functioning motor in for credit.

We recently rebuilt some Fanuc AC Spindle Motors, including one motor part number A06B-0828-B302. The customer was in a rush and needed this 357 lb motor so that he could get back up and running right away. We didn’t have the motor in stock, but we did have all of the parts in stock to build the motor. Check out all of our Fanuc CNC products on our website.

Within 3 days we were able to rebuild, repaint, and fully test the motor with our FANUC Spindle drives to get it ready to go back out via freight to the customer, so they were back up and running in less than a week.

Our rebuilds for these size motors usually take 2-3 days, so we were right on schedule for this Fanuc motor. We have the full list of motors that we stock and repair here, and you can email sales@mroelectric.com for more info. We also have pictures of the finished product below as an example.

Benefits of Buying Refurbished Industrial Automation Equipment

Joe Kaminski Leave a comment

At MRO Electric and Supply, we offer a wide range of repaired, refurbished and reconditioned automation products for each of our manufacturer lines. We never supply used, untested, second-hand parts. Each of our refurbished parts is fully cleaned, serviced, functionally tested, and upgraded to optimal working order before being made available for sale. We also place each of our reconditioned products in like-new packaging for easy identification, transportation, and storage.

Benefits of Refurbished Automation Products:

1. Availability
For many obsolete and legacy automation product lines, finding new, unused parts can be a challenging task. Oftentimes, searching for unavailable new parts can cause unreasonably long lead times which increases the risk of downtime. MRO Electric stocks a variety of refurbished products with same-day and next-day shipping options, while keeps the risk of downtime to a minimum.

2. Price
Refurbished products tend to be significantly less expensive than new parts. MRO Electric offers many refurbished items for up to 75% less than their new counterparts. This deep discounting allows our customers to stock up on spares while minimizing their costs.

3. Equivalence
Purchasing an exact replacement prevents compatibility issues versus upgrading to a newer component. For some manufacturers, it is better to stick with tried and true systems than risk purchasing a different part that may not function correctly with their process.

4. Reliability
Just because a part has been refurbished does not mean that it won’t last as long as new. Additionally, many of our refurbished parts have seen little or no use throughout their lifetime. We are extremely confident in the reliability of our refurbishment process, and warranty all of our products for a minimum of 12 months.

Enhance System Performance with Modicon Quantum I/O Modules

Joe Kaminski Leave a comment
Substation I/O modules for direct 125 Vdc control
Quantum I/O modules are available for direct connection to critical 125 Vdc battery powered equipment such as circuit breakers, protective relays, transformers and capacitor banks.

  • Built-in high transient noise immunity ensures reliable operation in harsh 125 V DC environments.
  • The 125 Vdc 30A high current output module eliminates expensive high current interposing relays used in breaker tripping and closure.
  • The solid-state 125 Vdc low current output module ensures long life and trouble-free operation in higher frequency 125 Vdc switching environments without the use of expensive external snubbing circuitry.
  • Over-current/ short circuit diagnostics and protection on all solid state 125 Vdc outputs reduce downtime by ensuring quick identifi- cation of circuit prob- lems and fast repair.

Latch/Interrupt module for time critical applications
The Quantum Latch/ Interrupt module is a multi-purpose high speed input, latch,
and interrupt module combined, which is configurable through programming software. Interrupt handling instructions are part of the 984 Ladder Logic instruction set. Quantum throughput performance for 2 interrupts is typically 1ms.
High speed counters don’t miss a pulse
Quantum high speed counter modules, such as the 140EHC10500, have the ability to count pulses at speeds much faster than the Quantum controller can directly do by itself. These modules automatically report the current count to the Quantum controller every scan.

Simple ASCII exchanges
The Quantum ASCII module is a general purpose ASCII interface that provides the ability to communicate and ex- change data with devices including printers, bar code readers and scanners, weigh scales, and meters. This module is designed for relatively simple point to point ASCII communications, with ASCII messages stored inside the module triggered by logic within the Quantum controller.
Yaskawa V1000

Yaskawa V1000 – Compact Vector Control Drive

Joe Kaminski Leave a comment

The Yaskawa V1000 is a compact current vector drive with dual microprocessor logic. There are 3 primary models: 200V 3-Phase Input, 200V Single-Phase Input, and 400V 3-Phase Input.  It is possible to run the drive without connecting the digital I/O wiring.

It is important when installing Yaskawa V1000 drives that proper electrostatic discharge (ESD) procedures are taken. Failure to comply could result in an ESD discharge that could damage the drive circuitry. If the drive is being operated at low speeds, the cooling effects are diminished and motor temperatures can increase which can lead to overheating. Continuously operating an oil-lubricated motor in the low speed range may result in burning.

A dynamic braking resistor can be used with the V1000 series. Dynamic braking helps bring the motor to a smooth and rapid stop when it is working with loads of high inertia. As the drive lowers the frequency of a motor with high inertia connected, regeneration occurs. This can cause over-voltage when the regenerative energy flows back into the DC bus capacitors. A braking resistor can help prevent these overload errors from occurring.

The drive functions are devided into 2 primary groups that are accessible through the Yaskawa V1000’s digital LED operator. Drive mode allows for motor operation and parameter monitoring. Parameter settings cannot be changed when functions are accessed in drive mode. However, alarm information and history can be accessed in drive mode. Programming mode allows access to the setup. There you can adjust and verify drive parameters as well as Auto-Tuning. The drive will not allow motor operation changes such as start and stop when the LED is accessing a function Programming mode. The V1000 is set to Drive mode when it is first powered up. The Up and Down arrow keys can be used to switch displays.

MRO Electric and Supply carried new and refurbished Yaskawa V1000 Drives. For more information or to request a quote, call 800-691-8511 or email sales@mroelectric.com.
