Easy control of Delta VFD drives

This week we would like to show you two new function blocks (FB) that we have developed to make even easier to use Delta Industrial Automation products.

Usually we need to control several AC drives from a single Master PLC and Modbus communication is a cheap and helpful way to get it.

In order to reduce programming and commissioning time we have developed two FB:

  • COM2_VFDLINK: Configures the communication parameters (baudrate, number of bits, parity,…) that all the nodes on the network have to share and informs about the communication state of each node.
  • DELTA_VFD: Controls each one of the slaves VFD, we can Start/Stop, Forward/Reverse, frequency command and reset faults. On the other side, the FB informs us about the status of the drive, alarm code, output frequency and output current.

Below you’ll find the FB library ready to be imported in your ISPSoft and a little pdf explaining the I/O of each FB, enjoy it!

Successful Application: Top cleaner greenhouse deck

Another successful application from our parters in Netherlands Innomotion.

On below video new top cleaner unit for cleaning the glass roofs of greenhouses, and since last year fully equipped with delta inverters

For the cleaning brushes they use VFD-L, And to drive the car over the roof our VFD-E.
And finally to control all the sequence a simple SS2 makes all the job.

Congratulations Innomotion!

Successful Application: 11 Axis Cutting / profiling machine

Another successful application from our Netherlands distributor Innomotion.

This time is a Woodcutting / Profiling machine with 11 axis control!

As you can see on the picture our partners use 7 VFD-E drives for transportation and high speed spindle, and 4 servodrives ASDA-A2 400W for the cutting/profiling.
Everything controlled by central CPU with Master CANopen module (DVPCOPM-SL).

Via the PC Cad drawings are imported to the Machine and machine settings are executed. The PLC is controlling all the I/O and servo’s for the motion.
In this machine the wooden boards for the stairs are cut to length , width and angle on front and end of the board. The PC software is written in Labview.
