Benefits of Buying Refurbished Industrial Automation Equipment

February 27, 2017May 14, 2021 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

February 24, 2017March 5, 2020 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 – Compact Vector Control Drive

February 14, 2017May 28, 2019 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.

Yaskawa CIMR-AU4A0038FAA A1000 Drive – Product Spotlight

February 1, 2017March 5, 2020 Joe Kaminski Leave a comment

The CIMR-AU4A0038FAA is a three-phase 400 Volt AC Drive. There are two modes on this AC drive – Programming Mode and Drive Mode. In Drive Mode, the user can operate the motor and observe U monitor parameters. Parameter settings cannot be changed or edited while in Drive Mode. In Programming Mode, the user can edit and verify parameter settings and perform Auto-Tuning. When the drive is in Programming Mode, it will not accept a Run command unless b1-08 is set to 1. If b1-08 is set to 0, the drive will only accept a Run command in Drive Mode. After editing the parameters, the user must exit the Programming Mode and enter Drive Mode before operating the motor.

Check out our website for all of our Yaskawa products!

Local mode is when the drive is set to accept the Run command from the digital operator RUN key. Remote mode is when the drive can be set to accept the Run command from an external device, such as input terminals or serial communications. Switch the operation between Local and Remote using the LO/RE key on the digital operator or via a digital input. After selecting local, the LO/RE light will remain lit. The CIMR-AU4A0038FAA will not allow the user to switch between Local and Remote during run.

Several Application Presets are available to facilitate setting up the drive for commonly used applications. Selecting one of these presets automatically assigns functions to the input and output terminals and sets a predefined number of parameters to values appropriate for the selected application. An Application Preset can either be selected from the Application Selection menu in the Setup Group or in parameter A1-06. The default parameter setting is 0, which disables the presets. The following setting ranges are listed below:
– 0: Disabled
– 1: Water supply pump
– 2: Conveyor
– 3: Exhaust fan
– 4: HVAC
– 5: Compressor
