Ten Simple Steps for KEB F5 Startup

Here's how to use our KEB F5 drive to rapidly and successfully start up an asynchronous induction motor. The programming procedure can be divided into 10 easy parts using KEB's programming tool, COMBIVIS 6. Read CM Industry Supply Automation - Servo Drive & Servo Motor Expert complete blog below.

We'll focus on a KEB F5 startup under closed-loop control with encoder feedback in particular. Other motor and control kinds will follow a similar basic procedure.

What am I going to need to start?

A VFD control technique known as closed-loop control with encoder feedback makes use of measured speed feedback via an encoder device.

Generally speaking, a KEB F5 starter using your specific motor will need five essential parts. As follows:

•     Energy Source (F5 offers DC, AC 3-phase, and AC 1-phase input options.)
•     F5 Drive a three-phase AC motor (either synchronous or induction).
•     VFD configuration with encoder feedback mechanism COMBIVIS 6 programming software

We can start COMBIVIS 6 and start programming as soon as we have connected our devices and power in the proper ways.

The F5 keb drive does not have integrated programming wizards, and programming is solely parameter-based, in contrast to the S6 drive initialization. In order to demonstrate how to quickly and simply program and start up the drive, we will develop a startup parameter list. For your convenience, we will build a parameter list that complies with the F5 Application Manual, which is a free resource for customers.

Control Type and Speed in Step 1

We will configure the Ud.02 control type to "4: F5-M / 4000 rpm" starting with Step 1. This establishes the drive for an asynchronous induction motor's operation, with a reference speed cap of 4000 RPM.

Enter factory settings on step two.

Step 2 of the parameter list uses the option Fr.01 to reset the drive's parameters to their factory defaults. This guarantees that we are beginning from scratch with our parameterization.

Configure the speed control in Step 3

In step three, we turn on closed-loop control with encoder feedback for the drive.

Set the feedback source in Step 4.

Set the feedback source to encoder 1 in Step 4.

Set the Encoder PPR Value in Step 5.
Since we are utilizing an incremental encoder for our startup, we must set the pulses per revolution (PPR) in the Ec.01 parameter.

Step 6: Enter the motor rated information

Step 6 requires us to enter the motor-rated information, which is normally taken from a motor specification sheet or the actual motor nameplate.

We require the induction motor's rated current, rated speed, rated voltage, rated power, rated power factor, and rated frequency. During the motor identification in Step 9, the resistance and inductance values discovered in parameters dr.06 to dr.10 will be computed automatically.

Step 7: Change more parameters

We are going to change a few settings that are essential for closed-loop control to function properly in Step 7. These settings enable current decoupling, enable the activation of the motor model, and establish the correct flux control. The F5 Application Manual guides the assignment of these parameters.

Set the maximum command speed in step 8

We will set the maximum command speed for this startup in Step 8.

After completing Step 8, our programming is complete, and we are now prepared to download our parameter list onto the F5 disk.

By selecting the green down arrow in the toolbar that says "download list to the device," we may download the parameter list into the associated F5 drive. To download, select "Yes." It will download the list to the drive. The "Offline value" column is subsequently written into the "Online value" column as part of the parameter download procedure.

Motor identification is step nine.

Now that the drive has been configured, we may proceed to Step 9, which is the identification of our motor. The motor identification can be accessed by first selecting the drive tab, then selecting "Online Wizards," and then selecting "Motor ident."

10th step: Test the motor

Once the motor identification is complete, we can review the parameter list to see how the motor identification has changed the inductance and resistance values in the F5 drive in real-time.

F5 Startup Summary

With a KEB F5 Drive, you have now successfully and swiftly started a motor.

An F5 drive has about 20 parameter groups, several of which were skipped over or were not used during this startup, as you may have noted. You would also check a number of other crucial parameters to finish commissioning your drive and motor for a successful integration into your industrial machine.
