TECO AC Drive Question

Wednesday, May 15, 2013
by Scott Welch

Question:

I have a Teco JNEV-203-H1 variable frequency drive that I just received. When enabled, it will run up and oscillate between 5-6 hertz. After I disable then re-enable and off we go and will run up to speed.

Answer:

This depends on the motor that is being used. We have seen this before with other vendors motors. Because the drive is defaulted in sensorless vector mode and the algorithms are pre-set for TECO motors, the units sometimes get "confused" by other motors in sensorless vector mode.

You should convert from Sensorless Vector to V/f

1. Set parameter F51 to 1 to access C parameters. Then Press the function button to get the C menu.

2. Set C14 = 001, and the problem should disappear.

Sizing A Variable Frequency Drive

Friday, April 12, 2013
by Beckie Bordenaro

I was hoping to make this into such a simple process that even I could do it... however, it's not quite that simple!

This blog will turn more into a 'here is the information you need to have someone who knows what they are doing size a drive'. That 'someone' could be our in-house tech support team, Scott and Chris!

Before you start looking at which variable frequency drive you want, get this information (hint: most of this information can be found on the motor nameplate!):

Horsepower
FLA (full load amps)
Voltage
RPM
Service Factor
Not required but good to know if the motor is inverter duty rated

There will also be questions asked about your application. Some of the common ones I hear are whether the load is constant torque or variable torque, what the speed range and control method is and if you have any special application requirements for the enclosure.

If you contact us with this information then I promise it will be a simple process, Scott or Chris will be able to recommend the best drive for your application! We stock a large amount of high performance AC drives from all the big names; AC Tech Lenze, Fuji Electric, Hitachi, TECO, Delta and more.

Baldor and The Movable Platform

Thursday, March 28, 2013
by Scott Welch

Question:

We would like options to use 110 volts and we try to avoid 220 or 240 volts because 220 volt outlet is 50 feet away from platform that is movable with 10 straight wheel casters.

Platform will be real heavy as it will need to hold 4 people and a huge bed.

Brand : Baldor
MAX INPUT:.471
Ratio 40
Output torque .1
461 in. lbs
ID#HF-918-40-BS or B5-H100
Cat. Spec GHF4018AH/GRO212B006
Serial#G24000153

Answer:

GH1/54C Teco Westinghouse 1.5 hp 230/460 three phase induction motor 56c frame with feet $213.60

ESV112N01SXB AC Tech 115 volt single phase input, 230 volt three phase output rated at 1.5 hp output - variable frequency drive

The gearbox you currently have will only take in .47 hp and will not stand up to a 1.5 hp motor.

I looked at Baldor and did not see a 40:1 ratio available at 1.5 hp. You have a little room on the gear ratio as the drive will help with the actual output speed but at 461 in lbs of torque that you are currently attaining, which is not nearly enough torque to do what you want.

A 1.5 horse power motor with a 40:1 would give you roughly 2160 in lbs. A 30:1 would get you to 1620 in lbs.

You can verify your torque needs by connect a torque wrench at the point where you couple to the platform. Load it up and give it several pulls and document the torque necessary to get the platform to move with a full load. This will get you in the ball park torque wise and then we will know what the best gear ratio for the application.

The drive will maintain torque through the speed range but will not increase the torque developed by the motor/gearbox combination.

Which Drive Should I Use?

Monday, March 11, 2013
by Scott Welch

Customer Question:

I need:

1. 2 each, VFD, for 4 hp motor, input power – 400 VAC, 50 HZ, 3 phase

2. 3 each, VFD, for 15 hp motor, input power – 400 VAC, 50 HZ, 3 phase

Notes:

1. Drives need to be NEMA 12 or better for water ingress.

2. Drives need to have Modbus RS 485 comms.

Our Recommendation:

I have attached the manual for these units. These both offer Modbus Communications and the Nema 4 enclosure you require.

MA7200-4005-N4 Teco MA7200 series variable frequency drive, 440 volt three phase input, 440 volt three phase output, rated for 5 hp in a Nema 4/12 enclosure $686.35

How To Adjust AC Drive Speed Using The Potentiometer

Saturday, March 9, 2013
by Scott Welch

Here is a question I received in my voice mail:

I have my TECO JNEV series variable frequency drive and cannot get the speed to change using the potentiometer. It is working fine using the up and down arrows but I want to use the potentiometer instead.

Here is my reply:

You need to go to parameter number F05 Frequency command source. The default on this is 000. You need to change to 001 to activate the potentiometer.

Question Regarding Dirty Power

Wednesday, March 6, 2013
by Scott Welch

Customer Question to Tech Department:

I'm having problems with a Teco N3 variable frequency drive. It is single phase, 240V input, 3 phase out (N3-2P5-CS) running a 1/2hp 1.66amp motor(3ph).

The parameters in Teco are good, the motor is good. It has been suggested to get reactor for potential dirty power (114v on one leg, 118v on the other).

I read their single phase note, which might be an MTE RL-00802 or the RLW series. Need help, need two in a snap base mount

Tech Department Answer:

Here are two options for you:

RL-00802 MTE Version Stock in Southern CA. 5-6 days delivery plus freight

KDRA25L TCI version List is $107.00 o/c $44.94..Out of stock but can build in three days.

Either of these options will work for you!
