Yaskawa DriveWorksEZ Application Guide

Chapter 3: Exercise 1 – Simple Widget Machine Control

1. Create a new project called “Exercise 1” and include your name and company name with the Project.
2. Create a project page called “Page One”.
3. Use the blocks described to accomplish the following:
   • 2 Digital Inputs (Terminals S6 & S7): Terminal S6 designated as “Run”, and terminal S7 as “Run Prohibit”. The drive runs ONLY if Terminal S6 is closed and Terminal S7 is open.
   • 2 Analog inputs added together (Terminals A1 & A3) become the frequency reference.
4. Successfully compile and download the project to a drive (if available).
5. Run the drive while monitoring with the DWEZ PC Tool.
6. Verify proper program operation before proceeding.

Chapter 5: Exercise 2 - Trolley Car Control

1. Create a new project called “Exercise 2” and include your name and company name with the Project.
2. Create a project page called “Over travel Control”.
3. Use the blocks described to accomplish the following:
   • 1 Analog input (Terminal A1) becomes the speed reference.
   • 2 Digital inputs (Terminals S1 & S2) become Fwd & Rev run.
   • 2 Digital inputs (Terminals S6 & S7) become N.C. Over travel Switches.
   • When the “FWD Over travel” switch is “tripped”, only reverse operation is allowed.
   • When the “REV Over travel” switch is “tripped”, only forward operation is allowed.
   • 1 Digital output (Terminal M5-M6) closes whenever either over travel switch is “tripped”.
4. Successfully compile and download the project to the demo unit.
5. Run the demo unit from the Virtual I/O while monitoring the status of the M3-M4 output with the DWEZ PC Tool.
6. Verify proper program operation before proceeding.

Chapter 6: Exercise 3 – Follower Reference

1. Create a new project called “Exercise 3” and include your name and company name with the Project.
2. Create a project page called “Follower Ref”.
3. Use the blocks described to accomplish the following:
   • Generate a frequency reference for another drive that will follow this drive's motor speed with a +/- trim.
   • Frequency reference for follower should be based off of MOTOR SPEED.
   • Trim amount should be entered via a parameter.
   • EXAMPLE: Motor speed = 50%, Trim = -10% → Frequency reference = 45%
   • Frequency reference should always be POSITIVE regardless of master motor direction.
   • Frequency reference should be sent to several places at once: An Analog output, a pulse train output (MP), scaling: fmax = 10kHz, and a keypad monitor.
   • There should be one monitor displaying master motor speed.
   • NOTE: Keep in mind that both motor speed and trim amount can be bi-polar. Select proper parameters and monitors.
4. Successfully compile and download the project to the A1000 demo unit.
5. Run the demo unit from the switch box (Virtual I/O) while monitoring the status of the follower frequency reference with the DWEZ PC Tool.
6. Verify proper program operation before proceeding.

Chapter 7: DWEZ Pro Story – Tank Level Control

1. Create a new project called “Tank Level” and include your name and company name with the Project.
2. Create a project page called “VFD Motor”.
3. Use DWEZ function blocks to accomplish the following:
   • Control the speed of a pump that is filling a large tank using the DWEZ-PI controller.
   • Ultra-sonic sensor above tank (0-10 VDC).
   • Noisy signal, due to “waves” in tank, filtering of feedback required.
   • Tank level settable via parameter.
   • Minimum motor speed settable via parameter.
   • Monitors for Tank Level & PI Error, and Drive output speed.

Chapter 7: DWEZ Pro Story - 2-Motor Tank Level Control

1. On the existing project called “Tank Level” ...
2. Create a new project page called “Line-Started Motor”
   • Digital output that starts line-started motor.
   • Start conditions: VFD at max freq. & liquid level below a settable parameter for a settable amount of time.
   • Stop Conditions: Drive not running, or liquid level above settable parameter for a settable amount of time.
   • NOTE: Some changes to the original “Tank Level” project may be required.
