2 Getting Started To get started, select File New Application Select Drive Series, Option Board, and Application templates, etc. For this tutorial, the Tritex II 230V AC drive series was used with an SIO Standard option board in a Generic application template

3 Getting Started Cont. Next, pick a location to save the application.

4 Overview of Layout Tritex Expert contains pages that have subpages within them. These subpages are where the user can specify the parameters that control the system and subsequently monitor the response.

5 Setup In the following slides, we will go over the subpages enclosed in Setup. They include User Units, System Setup, Tuning, and Factory Parameters.

6 User Units Select between linear actuator, rotary/gear motor, or a combination of the two. For rotary/gear motors, set the output gear reduction ratio. For this case, the distance output revs is post gear reduction while revs is used for pre-reduction. Choose the actuator lead and specify the distance, velocity, and acceleration units. The current can be displayed in amps or the percentage of range of the continuous o rating of the actuator.

7 System Setup This subpage allows the user to specify a variety of parameters to control the system. The contents t of the tabs (Options, Fault Enables, Comms Faults, etc.) are discussed in the following slides.

8 Options Auto-Enable on startup command is best suited for applications that use little l or no digital i input.

9 Fault enables This tab is used for controlling the actuator response when a fault occurs. Depending on the type of fault, select the appropriate drive response (i.e. stop, move, disable, warn, log).

10 Fault enables cont. If the continuous current box is disabled and the current is above the continuous current rating for more than two seconds, Tritex will issue a P- current fault to protect itself. Move termination faults occur when the move is supposed to terminate, but has not reached the desired position within the specified time period. The following error fault occurs when a commanded move falls outside of the following error specifications (set in the Limits tab).

11 Fault enables cont. Thelowandhightrip high limits are set in the Analog I/O page. Loss of signal is a fault for analog signals and is generally used with a 4-20 ma option board.

12 Comms Faults If the connection is severed for a specified period of time, then a fault will occur. Communication faults for Channel A (RS-485) and B (Ethernet).

13 Set these parameters related to the enabling of different faults: Limits User Current Limit Max Following Error Following Error Time Limit In Current Limit Time Stop Ramp

14 Operating Modes Select a default and alternative operating mode Click the arrow to drop down the list of available operating modes The Host operational mode is an active connection to the di drive and used dfor testing ti a direct MODBUS command

15 Operating Modes cont. The Host option is defined by the Host Control subpage under the Monitor/Control t page. To engage the alternate mode, click the Alternate Mode button under the Input tfunction Control lbox on the right-hand side of the screen.

16 Dedicated Move The unit moves to a specified position at a set velocity and acceleration when a fault occurs if the move box is selected in the fault enables tab.

17 In Position Window The Window Width is where the actuator is expected to be at any given time. Once a move completes and is within the Window Width for a specified time (Time To Activate), then the In Position output fires to say the position has been reached and the move is complete..

18 Position Limits This tab gives the ability to create software limits to control the response if the position falls outside the minimum and maximum absolute position limits. The jog functionality is used to control the velocity response if the position is outside the minimum and maximum absolute position limits

19 Position Limits Cont. For valve or damper control, to keep the valve closed, we can enable the max position limit to be our closed position. If we set the percent of analog range to 95%, anytime the unit is commanded above 95% it will move at a specified RPM until it reaches a seating current for a certain time period. After that set time period, a foldback current is initiated to keep the valve closed tightly. The Jog using position limit foldback current command dis used to limit i the amount of force produced using the jog commands, which can protect tooling or keep the unit from running into the end of travel too hard.

20 Tuning Tuning from the factory is generally acceptable, but if a higher performance is necessary use the scope to watch the profile and adjust the Inertia Gain and Response accordingly. Larger inertia loads will require a proportionally larger inertia gain value to maintain position and velocity control through a profile. Larger response values increase position stiffness, reduce error while running, and the time required to reduce position i error at a stop. An excessively large setting for inertia gain or response se will cause instability in the system.

21 Tuning Cont. Right click on this page and select Show Page Details This will reveal hidden tuning parameters that include Integral, Velocity Feedforward, and Velocity Damping (rotary applications).

22 Factory Parameters Parameters that you cannot change and are here eefor reference eee ceonly. This subpage contains the continuous current setting for the actuator and various other useful factory parameters located within the tabs

23 I/O Next, we will discuss the contents of the I/O page and how to configure the subpages.

24 Digital I/O This subpage contains input and output assignments. To assign parameters, click edit and use the drop down boxes to select inputs and outputs.

25 Digital I/O cont. These functions include modes, motions, moves maintained, moves active, control, etc. We can give the LEDs output assignments as well. Select the done button when finished assigning the inputs and outputs. Changing the polarity of the inputs and outputs will make them normally on vs. normally off.

26 Analog I/O This subpage is used to set up your analog range. It contains the tabs for Input Setup and Output Setup In the Input Setup tab select the appropriate mode Next, set the minimum and maximum voltage values of the analog system. The bandwidth is adjustable on this page, pg, allowing gyou to smooth out the analog signal if necessary. Once online, you will be able to see the voltage output under this tab.

27 Analog I/O cont. Select the output variable and units Set the minimum and maximum output limits The bandwidth is set to the highest amount here to ensure the fastest update rate.

28 Motion Now we will discuss the contents of the Motion page. pg

29 Home There are two ways to define the home reference. It can be done by jogging back and forth until a desired position is reached. Once this position is reached, select Define Home button from Input Function Control box.

30 Home cont. The other way to define the home position is by using the parameters Clicking the Terminate on Current Limit box will ensure the system will stop once the specified current limit is reached. This position will now be defined in the position register at the bottom of the screen. This page includes the option to terminate on switch active, which can be defined in the Digital I/O page. The home offset parameter can be used to move the unit off the bumper and update the final home position.

31 Jog This subpage allows for the manual override of speed control. It also gives data pertaining to the position and velocity of the unit.

32 Move Setup This page is where a lot of the digital motion will occur. Start by selecting the move number and move type. Next, set the position/distance, velocity, and acceleration.

33 Move Setup Cont. A secondary motion is available to initiate a command after the main motion has been completed. Useful applications include using the main motion to reach a position and the secondary motion to return it. The unlimited move type can be executed using the Terminate on current limit i option. Auto-Start Next Move is available to initiate a series of moves. The Wait for In Position command will check to make sure the move is completed before initiating the next move (defined in System Setup under In Position Window).

34 Analog Position Set the minimum and maximum position based on the minimum and maximum analog input. Also set up the velocity and acceleration limit in this page.

35 Analog Velocity Set minimum and maximum velocity, and acceleration limit. Use the negative sign for reverse motion.

36 Analog Torque Set the maximum and minimum i current tlimit. it This will use as much velocity and acceleration as it can until it reaches the set current limit.

37 Networks This page will show you the hardware and protocol specification the system is using to communicate Set parameters for Drive ID, Baud Rate, RX Timeout, and RX to TX Delay

38 Monitor/Control The following slides give an overview of the contents of the Monitor/Control page

39 Monitor This page pg displays the Position, Velocity, Current, Continuous Current, and Temperature of the system. It also gives the ability to activate/deactivate inputs and outputs.
