Benefits of Buying Refurbished Industrial Automation Equipment

At MRO Electric and Supply, we offer a wide range of 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.

FANUC CNC Troubleshooting – Frequently Asked Questions

MRO Electric stocks new and refurbished FANUC products, and also offers reliable FANUC repairs. Please call 800691-8511 or email sales@mroelectric.com for a quote.

What is the proper method to test a motor for a short?
The proper way to test a FANUC motor for a short is to first lock out the machine, remove the cable from the drive, and test all three motor phases to ground with a megohmmeter. This will test both the motor and the cable for problems.

Why am I getting errors when I connect to my FANUC drive’s RS-232 port?
There are a number of explanations for these errors. The RS-323 port is a high-fail component on a FANUC drive as it is very susceptible to electrical surges. However, the RS-232 cable is also another high-fail item. Ensure that you are using a cable that is known to be functional when communicating. Otherwise when you attempt to read-in or punch-out a cable, you will get an 086 alarm that is going to indicate that the cable is incorrect, or that the port has failed.

To test whether the cable or the port has failed, take a known good cable and insert it into the RS-232 port. Next, set your machine up to receive a file. The screen should being to flash “READ”. Next, transmit your file into the machine tool. If the machine continues to flash “READ” (or “LSK” on modern controls) but never receives the file, you have a defective communications port on either the memory board or the master board. These boards or your machine will need to be sent in for repair.

What is an Axis Communications Error?
An Axis Communications Error indicates a communications problem between the motor encoder and the CNC control. This can be caused by the motor encoder itself,  the cable going to the encoder, or the axis control card the cable is plugged into.

What is an Excess Error Alarm and why is it caused?
Generally, an Excess Error means that the machine has moved beyond its allowable tolerance. The CNC has told the servo drive to make a move, the servo drive moves the motor,  which in turn moves the encoder. As the machine moves, there will be some deviation. This deviation is known as the Excess. The parameters set how much deviation/excess should be allowed.

These errors can be caused by a variety of problems. For example, a dull tool can caused the axis to be pushed out of position which results in a deviation error. Debris build up can cause deviations while the machine is stopped. Additionally, a failed servo drive can also cause deviation errors.

What is FANUC Alarm 401?
Alarm 401 is a very generic alarm. It simply means that the servo’s did not obey. The CNC, which is in charge of the servos, tells the servo drives to turn on and remain on. If for whatever reason the servo drive turns itself off without the permission from the CNC, the CNC will generate a 401 alarm. This alarm will usually occur with other alarms, such as the 414 Alarm.

What is FANUC Alarm 414?
The 414 Alarm is an alarm issued by the CNC that says a problem has been found in either the servo drive or the feedback system. The alarm will show which axis is causing the problem. To identify the specifics of this alarm, you must go into the CNC diagnostics page. Diagnostics number 200 on the 16th row will indicate what is causing the problem.

What is the difference between a High-Current Alarm and an Over-Current alarm?
A high current is an abnormal current that can be caused by noise. When the system detects this, it will generally shut the machine down and generate a High-Current Alarm. This alarm is usually caused by defective servo drive or cooling contamination inside of the motor windings or cable.

An Over-Current Alarm indicates that too much current has flowed through the DC link. This is usually caused by a short in the system, an unplanned contact, a defective transistor module, or dull tooling attempting to make a cut. 

Why do I get a Soft Overtravel Alarm when I try to reference a newly installed motor?
When the CNC power down, it remembers its last known position. When you restart the machine, an incremental encoder will ask that the machine be re-positioned. When you try to do a re-reference of the machine tool, and it doesn’t agree with where the last known position was, the machine with automatically go into a default that indicates a Soft Overtravel Alarm. These alarms can occur as any point in the travel of the machine. To bypass this alarm, power the machine down and hold down the key with the letter “P” on it as well as the “Cancel” button (at the same time). Then power the machine up while you continue to hold down both of these buttons. If you do this, the machine will ignore all Soft Overtravels until the first zero referenced position has been done on that axis, and will clear the Soft Overtravel Alarms.

I unplugged my motor, and now I am getting a 300APC Alarm. What is that?
A 300APC Alarm indicates that you are using an absolute pulse coder. The difference between an absolute pulse coder and a incremental pulse coder deals in the memory retention of the position. Using a CNC control with an incremental pulse coder, you must reference the machine every time you turn the machine back on.

With an absolute pulse coder, there is a battery backed memory that retains the position of the machine tool when it powers down. When the CNC machine turns back on, it asks the encoder its position, and the encoder then responds back with its current position. If it is within tolerance of where it was when it shut down, the CNC will continue to run the program. However, if you lose the memory retention due to an encoder cable being unplugged, you will end up with the 300 level APC alarms. These alarms simply signify that the machine must be re-referenced. The re-referencing procedure is determined by the machine tool builder – consult your machine tool builder manual for the proper operation.

The unit’s enhanced inertia matching precision gets rid of the need for servo gain adjustment. The use of the serial encoder allows for the SGDM-04ADA to automatically sense motor capacity and type, which lets it automatically set motor parameters. The module also has built-in cumulative load factor monitoring and regenerative load ratio monitoring. It can connect to standard PC interfaces to allow for waveform display monitors, and can also be controlled through a digital operator, even without inputting speed commands.

SGDM-04ADA Wiring Configuration
SGDM-04ADA Wiring Configuration

There are a few precautions to take before putting your SGDM-04ADA into operation. Firstly, never connect a 3-phase power supply to the U, V, or W output terminals as this could result in injury or fire. It is also crucial that users never touch the power terminals on their Servopack for at least 5 minutes after turning the power Off since high voltages could still be present. One should also install the battery at either the host controller or the Servopack of the encoder. If both batteries are installed simultaneously, there will be a loop circuit between the batteries.

Micromaster 420

Siemens Micromaster 420 Faults and Alarms

A blog we posted earlier this week about the Micromaster 420 troubleshooting referenced the Faults and Alarms list for the Micromaster series, so we decided that it would make sense to make the list of Micromaster 420 Faults and Alarms directly available. This is from the corresponding manual for the Micromaster 420 series, but it is buried within the manual which most people most likely don’t even have. Hopefully this helps with your troubleshooting.

Schneider Electric TSXCUSBMBP: Beyond the User Manual

Need a replacement TSXCUSBMBP? Request a Price Quote Now.

The Schneider Electric TSXCUSBMBP is a USB Modbus Plus Communications Adapter. In this guide, we will show you how to install the hardware, configure the driver software, and use the Modbus Plus network diagnostics features of the driver software.

Important: The least versions of the TSXCUSBMBP driver to run on Win Server 2012 R2 are driver versions 8.0 and 8.1.

The TSXCUSBMBP is designed to bridge the gap between a USB connection and the Modbus Plus network. It combines hardware and software together in one simple and single device. The module has its own Modbus Plus node address which can be set through the TSXCUSBMBP driver software. This module allows software applications using the serial Modbus RTU communications to connect on the high-speed Modbus Plus network, as well as provide diagnostic capabilities to the Modbus Plus network.

Most Win32 Applications that support serial Mdubus communications can use a Modicon TSXCUSBMBP to connect on a Modbus Plus network. A VSP (Virtual Serial Port) is what redirects communications from Concept, Unity, ProWorx32 and other programs to the TSXCUSBMBP communications adapter. After the VSP is installed, it will create one serial port with the port reference as defined in the module’s driver software. When configuring the Modbus application software, this port reference is selected as the serial port for the application to use. The routing table is used to associate Modbus Slave IDs with 5-byte Modbus Plus routing paths which allow the application software to communicate with any Modbus Plus device within range on the network.

The TSXCUSBMBP’s hardware consists of a box with a USB cable from one end (which connects to the PC) and a standard Modbus Plus DB9 connector on the other end (for the Modbus Plus network). Local signalling LEDs on the top cover of the device tell you the presence of power from the USB port and the state of the Modbus Plus network – no external power supply is required.

TSXCUSBMBP Installation

To install the TSXCUSBMBP, you will need the following:
– Windows XP Operating System with service pack 2, or Windows 2000 with Service Pack 4 or greater.
– 1 MB of free disk space.
– Minimum of 256 MB of RAM.
– One free USB port or a USB Hub that supports USB 1.1 or greater.

If a previous version of the TSXCUSBMBP was installed, the VSP component of the driver must be manually uninstalled using Device Manager before a new version can be installed. After this, the new driver should be installed before connecting the new TSXCUSBMBP to the PC. After the new driver is installed, connect the TSXCUSBMBP and install using the New Hardware Wizard. After completing the instructions, you should see a message stating “Your new hardware is ready to use.” Restart your computer, and the device should be fully functional. If the driver starts up before the TSXCUSBMBP is connected, then it will be necessary to re-scan for adapters so the driver can detect it.

TSXCUSBMBP Configuration

To configure the module, you will need to do the following:

1. Configure the Modbus Plus Node Address
The communications adapter must be assigned a Modbus Plus node address to communicate on the network. Select “Settings” and then type the address in the appropriate box. When complete, hit “Save”.

2. Configure the Slave Response Timeout
The slave response timeout is used by the module each time it sends a request from an application out on the network to a slave device. Use the manual to determine the appropriate value that should be used with your system. Select “Settings” and then type the value in the appropriate box. When complete, hit “Save”.

3. Configure the Virtual Serial (COM) Port
To do this, select “Virtual Modbus Port.” Select the desired COM port from the list available. When complete, click “Save”.

If you experience any problems while configuring your adapter, please use the table below to determine the appropriate error code given by the LEDs, if applicable. As always, refer to the user manual for more complete information.

The Siemens 6SN1145-1BA01-0DA1 is a Simodrive Infeed/Regenerative Feedback Module with Closed-Loop control. This module is used to connect the drive group to the line supply. Specifically, it is used to input power into the DC link. It also provides the electronics power supply for the connected modules. The 6SN1145-1BA01-0DA1 does not have an comprehensive overload protection. This protection must be provided by the configuration and the correct setting of current values on the control boards.

The 6SN1145-1BA01-0DA1 forms the step-up converter for controlling the DC link voltage and allowing a regenerative feedback. This module can be used for a variety of applications, including the following:

  • Machines with high dynamic requirements placed on the drive.
  • Frequency braking cycles and high braking energy.
  • Control cabinet designs optimized for low operating costs.

This I/R module, the UI and monitoring module are located as the first module to the left of the drive group. The mounting surface of the infeed module and drive modules as well as the commutating reactors and line filter should be mounted to the mounting panels through a low resistance connector like  galvanized plates or panels.

The 6SN1145-1BA01-0DA1 has a total of 6 LEDs for local signaling as show below:
