How to Program a TECO Westinghouse L510

April 27, 2023

In this article, we’ll walk through the basic set up for an L510 TECO Westinghouse VFD. This is a medium-duty, advanced micro-drive that’s ideal for compact applications. Its low cost compared to other models and its easy programming makes this drive popular for OEMS.

VFDs are sensitive electrical equipment that can be easily damaged if handled or installed incorrectly. A qualified professional can help ensure that no damage is caused.

This article covers basic set up. Find the full parameters set up in the L510 manual, starting on page 4-8.

L510 VFD Parts

Starting with the face of the VFD, let’s go over the different elements including the enclosure, operator panel, commutator port, and terminals.

Enclosure

This particular VFD should always be mounted in a clean, dry, and warm environment. Make sure you get the appropriate enclosure for your application. If your VFD is just going in your shop, a simple vented enclosure will do. If you’re mounting it outside and you’re in Canada, you’ll probably want a heated enclosure. Or if mounting in a dirty application, you’ll want an enclosure with a filter. You can buy VFD enclosures at most industrial wholesalers. Most commonly, you’ll use a NEMA4 enclosure, which will protect against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water.

Operator Panel

The operator panel, or keypad, is where you’ll configure settings and, in cases without external controls, this is the control center for your motor. The mode button gets you into the parameter settings menu and back into run mode once you’re done making your changes.

The arrows and enter buttons help you navigate the menu to find the settings you’d like to change.

And finally, the knob is the potentiometer. This is how you adjust the frequency to control the power output and speed of your electric motor.

Commutator Port

This VFD also includes an RS485 communication port. This is where you’ll hook up your laptop if you intend to configure settings that way. You can also copy the settings from one drive to apply them to another.

Terminals

Now, looking at the front terminals where you’ll connect any external controls – RA and RB are relay outputs. These terminals are used to operate another component that operates with the motor. For example, indicator lights or fans.

The COM to S5 terminals are for digital inputs.

COM is the common or neutral that completes the circuit.

S1 to S5 are the terminals where you will connect buttons, switches, sensors, etcetera.

And then 10-V to AGND are analog inputs and outputs.

10-V is the 10-volt DC power output for the connected device.

AVI is the analog voltage input, ACI is the analog current input, AO is the analog output, and AGND is the ground. These analog inputs allow for the connection of external controls that create variations in speed as represented by a curve, like float sensors or a potentiometer.

L1, L2, and L3 are the connections to provide single or three-phase power to the VFD. In single-phase setups, L1 is the power input and L3 is the neutral. In three-phase setups, L1, L2, and L3 are each connected to a phase.

T1, T2, and T3 are the output lines that go to the motor. And these right here are the ground terminals.

Basic Parameter Set Up for TECO L510

We’ll make these power input connections to start up our VFD and start configuring for your specific motor.

Keypad Set Up

On the first power-up, we have to do the keypad setup. Press ‘mode’ until you see four digits separated by a dash, like below. Press enter and use the up or down arrow keys to find “00-00 Basic Function,”.

We’ll set 3 parameters, including motor rotation, main run source, and frequency command source. This is everything you need to know for the basic set up.

Motor Rotation

We’ll set motor rotation under 00-01.

  1. First we’ll navigate to 00-01 and long press enter.
  2. Set this parameter to 0 for forward rotation or 1 for reverse rotation.
  3. Long press enter.

Main Run Source

Next, we’ll look at how you want to control the motor under 00-02.

  1. Navigate to 00-02 and long press enter.
  2. If you want to control your motor through the VFD, you’ll want a value of 0. If you want to control the motor with a start-stop switch, you’ll use a value of 1.
  3. Make your selection and long press enter.

Frequency Command Source

Next, we’ll determine the frequency command source under 00-05.

  1. Navigate to 00-05 and then long press enter.
  2. If you want to control the frequency through the keypad, keep the value at zero. If you want to use the VFD potentiometer, change the value to 1. If you prefer to use an external potentiometer to adjust the frequency, change the value to 2.
  3. Make your selection and long press enter.

Motor Parameters

Let’s head back to the group list and start inputting our motor data into the VFD. You’ll find all this info on your motor nameplate. In some cases, the nameplate won’t have all of the information you’re looking for. That’s fine, just use whatever information you have.

Motor Current

We’ll set the motor current under 02-01.

  1. Navigate to 02-01 and long press enter. Here we’ll set the parameters for the motor current.
  2. Find the current rating on your motor nameplate, which might be indicated as amps, FLA or current.
  3. Set the parameter and long-press enter to save.

Motor Rated Speed

The next parameter is motor-rated speed under 02-03.

  1. Navigate to 02-03 and long press enter.
  2. Our motor is rated for 1800 RPM, so we’ll set that, and long-press enter.

Motor Rated Voltage

Next is the motor-rated voltage under 02-04.

  1. Navigate to 02-04 and long press enter.
  2. Set the voltage corresponding to your motor nameplate.
  3. Then long-press enter to save.

Motor-Rated Power

We’ll find motor-rated power under 02-05.

  1. Navigate to 02-05 and long press enter.
  2. This setting is rated as kilowatts.
  3. Make your selection and long-press enter.

Motor Frequency

And finally, motor frequency under 02-06.

  1. Navigate to 02-06 and long press enter.
  2. Make your selection and long press enter to save.
  3. Now your VFD is set up for your specific motor.

Maximum and Minimum Frequency Outputs

Let’s take a look at the maximum and minimum frequency output. Setting this parameter will help to ensure that the motor isn’t operated outside of its rated speed range.

00-12 is for the maximum frequency and 00-13 is for the minimum frequency.

  1. Navigate to 00-12 to set your maximum speed and long press enter.
  2. Set your max frequency and long press enter to save.
  3. Press the up arrow once and long enter again to set your minimum speed.
  4. Your minimum frequency might be zero, or if you want the motor to always be running at a low speed your 00-13 parameter will be higher than zero.
  5. Make your selection and long press enter.

Accelerator and Deceleration Times

We can also play with the acceleration and deceleration times. This is the amount of time it’ll take to reach a certain speed or the amount of time it takes to stop the motor.

Acceleration is under 00-14.

  1. Navigate to 00-14 and long press enter to set your acceleration. The units for this parameter are in seconds. Make your selection and long press enter.
  2. And then we’ll do the same for deceleration, which is under 00-15. Press the up arrow once, long-press enter and determine how many seconds you want it to take for the motor to stop the motor.
  3. Make your selection and long press enter.

Now we can run the motor, change speeds to go faster or slower, and then stop the motor, all from the VFD.

Factory Reset L510 TECO VFD

Last but not least, let’s talk about factory reset. Say you’ve decided to use your VFD in a new application, or maybe you’ve just been playing with the settings so much that it’s time to reset the whole thing.

We’ll hit mode and use the enter button and arrows until we get to 13-08, and long press enter.

The number you want to enter here is based on the drive’s frequency and voltage ratings, and the power available to your building.

You’ll find the list of available options in the drive’s instruction manual.

Make your selection and long press enter.
