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 Lucy Had a Yaskawa VFD, This (Episode) Wouldn’t Have Happened

Because a Yaskawa VFD would have allowed the operators of the candy factory to slow down or even reverse the conveyor belt. Instead, they were probably running an old DC motor with in-rush current starts and stops and draining their electricity use. Does this sound like you?

I, for one, am extremely happy they DID NOT have VFDs in the 1950s — lest we’d have never had this classic episode of I Love Lucy, which was bad luck for Lucy and Ethel.

AC Controls System Save Money vs. DC Systems

Can an AC controls system save you money vs. a DC controls system?

Here is an interesting slide from our recent webinar, "DC to AC Drive Retrofits." Over the expected life of a DC motor, you can expect to spend nearly $600,000 in repairs, maintenance and field service costs. This cost includes the associated downtime opportunity costs, too. So if you make the decision to change from DC to an AC controls system today, find a great partner. You won't have to worry about the AC drive maintenance costs....leave that for the next guy who replaces you after you're promoted for making wise decisions.

The webinar brought up some interesting considerations concerning AC controls systems vs DC control systems. AC wins on energy consumption, yet DC wins or ties on many other performance factors which are explained in the presentation. However, AC control systems enjoy far less downtime and repair/maintenance time than DC. Given that all downtime has a negative production cost, an AC controls system (as you can see in the chart below) wins BIG in the long run.

The DC to AC Drive retrofit webinar is available to watch on demand here.

AC Systems Save Money

If you decide to replace your DC motors with an AC controls system, it will be the next guy -- not you -- who worries about the maintenance of the AC system.

AutoTune an AC drive with a Cheat Sheet

Posted May 20, 2016 by Pepper Hastings

Categories: AC Drives, Blog

To AutoTune an AC drive seems like a complicated task that requires technical experience. While the devices themselves can be used for complicated tasks, setting them doesn’t have to be difficult. Many AC drives can be AutoTuned and program themselves if you follow a basic set of instructions generally provided by the manufacturer.

And it’s not the programming manual.

Programming manuals can be daunting books to read through with a lot of numbers, charts, diagrams and text that is easy to get lost in. The solution is something else: The Cheat Sheet.

Cheat sheets are nifty charts that walk you through the process of wiring the motor to three or four simple parameters then guide you through the actual process of setting up and auto-tuning your AC drive.

Many manufacturers and sellers provide cheat sheets and manuals on their website so coming by this information can be as simple as performing a Google search. A search for ‘Yaskawa cheat sheet’ brings up five or six cheat sheets alone for their AC drives.

Yaskawa provides multiple cheat sheets AutoTune an AC Drive. It ranges from the Yaskawa v1000 to the higher-featured a1000 drive.

Quick Start Guides will provide a bit more detail than cheat sheets and are another simple resource for installing an AC drive. They have flow charts, walking you through each step in order to have your drive operating as soon as possible.

Of course, if your task is more complex then a manual may be your only option. They have every detail about every parameter and are useful for experienced technicians.

Check out our website for an extensive list of AC drive information like cheat sheets, manuals, tips and online resources.
