Another Happy Industrial Repairs Customer

Our latest industrial drive maintenance (IDM) customer is a Houston area steel processor who recently had a 300HP Allen-Bradley VFD on his leveler machine go down for almost a week. It' s part of his blanking line.

The customer had been using another field service company to service his equipment, but that group fried the VFD while troubleshooting. The customer said to IIDM, “Come on down, we need your help ASAP”.

We took the big drive to our repairs depot in NW Houston and were able to evaluate the drive the same day (within hours). The customer approved the repairs quote. The drive was repaired, tested, and ready for a weekend install by IIDM field service techs. Our field service guys arrived with the drive on the weekend and a couple of hours later, the customer's line was up and running again.

If you need help with your AC drive start up, call us. We can help.

Here are some tips to help you with an industrial AC drive start up.

Before You Start

• VFDs are mounted in an appropriate environment and required input circuit protection.
• Install all electrical conduit, if needed, prior to the AC drive start up
• The electrical in/out 3Ø power cable have been pulled and are terminated onto VFDs.
• The AC motors are mounted and are uncoupled from the load, if possible, to facilitate an auto tune of the VFD with access to the motor name plate data.
• The communication signals are pulled and are near the field connection terminals on the VFD.

AC Drive Start Up Steps

• Verify the drive model number to ensure it's the correct model
• Ensure the area surrounding the drive complies with specifications
• Verify that the drive is properly sized to run the motor
• Confirm there is proper circuit protection as specified by national and local code
• Properly wire drive terminals R/L1, S/L2, T/L3 & R/T1. V/T2, W/T3 and control wiring
• Properly ground the drive and tighten control and grounding terminal according to specification
• Program the VFD according to the motor nameplate data and customer’s expectations
• Perform Auto-Tune based on control mode and other operating conditions.
• Verify rotation.

Innovative-IDM is an Authorized Service Provider and Distributor for Yaskawa VFDs. When we do your Yaskawa AC drive start up, you receive an additional year on your Yaskawa factory warranty -- a total of two years.

If you have a drive that needs to be repaired, we can help you with that, too. If I can be of any help to you, email me and I'd be glad to walk you through whatever I can. If you're not using VFDs, you could end up like Lucy in the candy factory.

Electronics And Heat Don’t Mix

As we here in Texas groan about high temperatures of summer, it’s important to remember that we aren’t the only ones suffering from the heat. Electronics and heat don’t mix and the combination can be disastrous.

As temperatures rise the number of businesses that lost power or experienced brown increase. During that time, many people turn on their generators or use battery power to keep machines running. What they didn’t realize was – the heat could be damaging their equipment.

Circuit systems within electronics work best at lower temperatures. Allowing systems to run for prolonged periods of time in high temperatures can decrease the longevity and reliability of devices. Solid state electronics actually begin to break down and fry at temperatures much above 120 degrees. However, the hotter the temperature – the less functional the machine will become. Most systems tend to run 10 to 20 degrees hotter than room temperature.

Within the era of technology electronic devices such as drives (VFDs), programable logic controllers (PLCs), human machine interfaces(HMIs) and power supplies have dramatically decreased in size. This causes a lot of systems to run with a higher heat density. While many companies have worked to include cooling systems within their products – cooling systems cannot keep up when devices are left in areas without air conditioning. Believe it or not, just surfing the web on your cellphone or playing games on your laptop may sound like the perfect idea during a blackout, but that heat can even damage them!

When the power is off or it is not stable and rooms temperatures are high, limit use of electronic devices.  Cooling units similar to small air conditioners can be purchased and installed to keep equipment cabinets cool.  Placing a fan in front of a cabinet with the door open will provide temporary relief, but could cause more environmental damage to the drive by allowing foreign material, dirt and water into the cabinet.  Just remember. The longer the use, the hotter the object will get.

If you experience issues with any electronic device after exposure to heat send it to Innovative IDM and we will provide a free evaluation. IIDM also stocks and sells new world class VFDs, PLCs and HMIs and can do turnkey installations. So, if you have a piece of equipment you’d like to check on repairing, contact your IIDM sale representative or email us at repairs@iidm.com.
