The two most common I/O Assembly Instances for the Toshiba AS3 Adjustable Speed Drive (ASD) are instances 100/150
and 102/152
. Instance 102/152
allows users to customize the type of I/O data using drive parameters C641 through C660. For additional information on AS3 Embedded Ethernet functionality and other I/O Assembly Instances, please refer to the E6582125 – AS3 Embedded Ethernet Function Manual, available at www.toshiba.com/tic/.
The Ethernet module configuration programmed in this document utilizes Instance 100/150
, which allocates 2 Words (16 Bits) each for the Output Control and Input Feedback.
Visual description: A screenshot of the "Module Properties Report" dialog for the Generic Ethernet Module. The "Connection" tab is active, showing the "Assembly Instance" settings for Input (150) and Output (100), with their respective sizes (2 Words, 16-bit). These parameters are highlighted.
Controller Output (ASD Input) Instance 100 utilizes 2 Words (0,1), with each Word labeled from Bit 0 to Bit 15. This instance is primarily used for Run/Stop and Speed Reference to the ASD.
The first Word in Instance 100 provides basic drive control functions such as preset speeds, forward/reverse, run/stop, emergency stop, fault reset, and communication override. For example, activating Word 0, Bit 10 will send a Run command to the ASD.
The second Word provides the speed reference to the ASD in decimal format, labeled in Hz. For example, entering "6000" in decimal format in Word 1 will result in a 60.00 Hz speed reference to the ASD.
Bit 0 | Bit 1 | Bit 2 | Bit 3 | Bit 4 | Bit 5 | Bit 6 | Bit 7 | |
---|---|---|---|---|---|---|---|---|
Word 0 | Preset Speed 1 | Preset Speed 2 | Preset Speed 3 | Preset Speed 4 | V/f Switching | PID Off | AccDec 1/ AccDec 2 | DC Braking |
Bit 8 | Bit 9 | Bit 10 | Bit 11 | Bit 12 | Bit 13 | Bit 14 | Bit 15 | |
Jog Run | Forward/ Reverse | Run/Stop | Free Run (ST) | Emergency Stop | Reset Trip | Speed Ref Override | Control Ref Override | |
Word 1 | Drive Speed Reference in Hz (decimal format) |
Similarly, controller Input (ASD Output) Instance 150 utilizes 2 Words (0,1), with each Word labeled from Bit 0 to Bit 15. This instance is primarily used for Status Feedback and Speed Feedback.
The first Word in Instance 150 provides basic ASD status feedback such as fault status, alarm status, undervoltage, running in forward or reverse, and ready to run. For example, an active Word 0, Bit 0 indicates the ASD is currently faulted.
The second word provides speed feedback from the ASD in decimal format, labeled in Hz. For example, receiving "6000" in decimal format in Word 1 indicates the drive is running at 60.00 Hz.
Bit 0 | Bit 1 | Bit 2 | Bit 3 | Bit 4 | Bit 5 | Bit 6 | Bit 7 | |
---|---|---|---|---|---|---|---|---|
Word 0 | Faulted | Emergency Stopped | Alarm | Under Voltage | V/F 2 | PID | AccDec Mode | DC Braking |
Bit 8 | Bit 9 | Bit 10 | Bit 11 | Bit 12 | Bit 13 | Bit 14 | Bit 15 | |
Jog Running | Forward/ Reverse | Run/Stop | Free Run (ST) | Emergency Stopping | Ready with ST | Ready without ST | Hand/Auto | |
Word 1 | Drive Speed Feedback in Hz (decimal format) |
The example screenshot illustrates that Controller Tags ASD_AS3:I.Data[0].0
, ASD_AS3:I.Data[0].1
, and ASD_AS3:I.Data[0].12
(Bits 0, 1, and 12) are active. This indicates that the ASD is currently Faulted, Emergency Stopped, and in an Emergency Stopping state.
Visual description: A screenshot of the Logix Designer "Controller Tags" window. The tag ASD_AS3:I.Data[0]
is expanded, and bits 0, 1, and 12 are highlighted and shown as active (value 1), representing "Faulted," "Emergency Stopped," and "Emergency Stopping" respectively.
The example below displays the Output Controller Tags for an AS3 drive operating at 60.00 Hz. From the Controller Tags window, expand the first Word under ASD_AS3.O.Data
to view the 16 Bits from the Output Instance 150 mapping.
To run the drive using the embedded Ethernet connection, both parameters CMod
(Run command select) and FMod
(Freq command select 1) must be changed to "Embedded Ethernet." By default, these parameters are set to "Terminal" and "Terminal RR."
Writing a value of 6000
into the second Word, ASD_AS3:O.Data[1]
, will send a 60.00 Hz speed command to the ASD via Ethernet/IP.
Visual description: A screenshot of the Logix Designer "Controller Tags" window. The tag ASD_AS3:O.Data[0]
is expanded to show its individual bits. The tag ASD_AS3:O.Data[1]
is highlighted, showing a value of 6000, representing the speed command.
Using the same project created previously, add three coils and a MOV (Move) block into the Start Stop rung within the "MainRoutine" ladder logic.
Point each coil to ASD_AS3.O.Data(0).10
, ASD_AS3.O.Data(0).14
, and ASD_AS3.O.Data(0).15
, which correspond to Run/Stop, Speed Reference Override, and Control Reference Override from Instance 150 mapping, respectively.
Move a speed reference value into the destination ASD_AS3:O.Data[1]
, which correlates to the second speed reference Word from Instance 150 mapping.
Once online, toggle the Start Contact bits to send a run command and a speed reference to the drive.
Visual description: A screenshot of the Logix Designer ladder logic editor. The "Main Program - MainRoutine" shows a ladder rung with a "Start Stop" input, three output coils (ASD_AS3:O.Data[0].10
, ASD_AS3:O.Data[0].14
, ASD_AS3:O.Data[0].15
), and a MOV instruction block transferring a value of 6000 to ASD_AS3:O.Data[1]
. These elements are highlighted.
