Accessory 36E ADDRESSING ACC-36E Dip switch (SW1) specifies the base address of the ACC-36E in a 3U TURBO / POWER UMAC, or MACRO Station rack.
Accessory 36E Hardware Address Limitations Two types of accessory cards have been designed for the UMAC 3U bus type rack; type A and type B cards.
Accessory 36E USING ACC-36E WITH TURBO UMAC Setting Up the Analog Inputs (ADCs) The A/D converter chips used on the ACC-36E multiplex the resulting data, and therefore it is mandatory to read each input one at a time. With Turbo UMAC, this can be done in two ways: Automatic Read Manual (semi-automatic) Read The automatic read feature is available with Turbo firmware version 1.936 or newer. It supports up to two ACC-36Es in one rack.
Accessory 36E Automatic ADC Read The automatic read function demultiplexes the data into individual registers and stores them in accessible memory locations. It can handle up to a total of 32 ADC channels. There are 16 ADCs (8 pairs) per base address (or ACC-36E card) for a maximum of 2 base addresses (or two ACC-36E cards).
Accessory 36E Automatic ADC Read Example 1 Setting up Turbo UMAC with an ACC-36E at base address $078C00 to automatically read all 16 ADCs, allowing the user to choose unipolar or bipolar mode: 1. A/D Processing Ring Size I5060=8 2. ; Demux 8 ADC pairs A/D Ring Pointers I5061,8=$400 ; ADC pairs 1 through 8 Offset width $400 = $078C00-$78800 3.
Accessory 36E Automatic ADC Read Example 2 Another ACC-36E has been added to a total of two cards respectively at $078C00 and $079C00: 1. A/D Processing Ring Size and Ring Pointers I5060=16 I5061,8=$400 I5069,8=$1400 ; Demux 16 ADC pairs ; ADC pairs 1 thru 8 offset width ; ADC pairs 9 thru 16 offset width $400 = $078C00 - $078800 $1400 = $079C00 - $078800 2.
Accessory 36E Manual ADC Read The manual read method consists of choosing the desired channel with a pointer, reading it, waiting for the conversion to finish, and then copying the contents of the result register into a UMAC memory location. The following are the necessary steps for implementing the manual ADC read method. The example parameters given here are for an ACC-36E at base address $078C00, allowing the user to choose unipolar or bipolar input signals: 1.
Accessory 36E 4. Using the Channel Select Pointer, specify the channel # and voltage mode as follows: ADC Channel ADC# Read by M5058 ADC#1 ADC#2 ADC#3 ADC#4 ADC#5 ADC#6 ADC#7 ADC#8 Channel Select Value ADC# Read by M5059 Unipolar Bipolar ADC#9 0 8 ADC#10 1 9 ADC#11 2 10 ADC#12 3 11 ADC#13 4 12 ADC#14 5 13 ADC#15 6 14 ADC#16 7 15 Data Read 5. Wait for the ADC Ready bits to become 1, then read and/or copy data from the Data Read M-Variables.
Accessory 36E ADC Manual Read Example PLCs Ultimately, the procedure above can be implemented in a PLC script to read all channels consecutively and consistently, creating a “custom automatic” function, as seen in the following examples. Unipolar PLC Example Setting up Turbo UMAC with an ACC-36E at base address $078C00 with all 16 ADCs as unipolar. This example uses M5000, M5002, M5004–M5006, and P2001–P2016.
Accessory 36E Bipolar PLC Example Setting up Turbo UMAC with an ACC-36E at base address $078C00 with all 16 ADCs as bipolar. This example uses M5001, M5003–M5006, and P2001–P2016.
Accessory 36E Testing the Analog Inputs The Analog Inputs can be brought into the ACC-36E as single ended (ADC+ & Ground) or differential (ADC+ & ADC-) signals. In single-ended mode, ADC- should to be tied to analog ground for full resolution and proper operation.
Accessory 36E Using an Analog Input for Servo Feedback The ACC-36E analog inputs can be used as a feedback device for a servo motor. Note Refer to Delta Tau’s released application notes or Turbo User Manual for cascaded-loop control (i.e. force, height control around position loop). The automatic ADC read function is recommended for this application. Example: Setting up Motor #1 position and velocity feedback to ADC channel #1.
Accessory 36E Analog Input Power-On Position Some analog devices are absolute along the travel range of the motor (e.g., in hydraulic piston applications). Generally, it is desirable to obtain the motor position (input voltage) on power up or reset. This procedure can be done in a simple PLC on power-up by writing the processed A/D data into the motor actual position register (suggested M-Variable Mxx62).
ACC-36E Manual USING ACC-36E WITH POWER UMAC Setting Up the Analog Inputs (ADCs) The A/D converter chips used on the ACC-36E multiplex the resulting data, and therefore it is mandatory to read each input one at a time. With Power UMAC, this can be done in two ways: Automatic Read Manual (semi-automatic) Read In either method, the user may use either Power PMAC Script or the C programming language.
ACC-36E Manual Automatic ADC Read The automatic read function demultiplexes the data into individual registers and stores them once every AdcDemux.Enable phase cycles in accessible memory locations. It can handle up to a total of 32 ADC channels (16 pairs). There are 16 ADCs (8 pairs) per base address (or ACC-36E card) for a maximum of 2 base addresses (i.e.

ACC-36E Manual Accessing AdcDemux Structures in C Code (Optional; For C Programmers) Having configured the Power PMAC to process the ADC inputs, the following example shows how to access the data in C environment. It reads the 16-channel ADCs in a CPLC and stores them in a user defined array (ADC_Result[] in the following example) whose elements can subsequently be used from within the C program as the user desires. #include #include #include
ACC-36E Manual Using an Analog Input for Servo Feedback The ACC-36E analog inputs can be used as a feedback device for a servo motor. For simplicity, the automatic ADC read function is recommended for this application. This example assumes that the automatic ADC read function has already been configured and activated. Example: Setting up Motor #1 with position and velocity feedback from ADC channel 1.
ACC-36E Manual Analog Input Power-On Position Some analog devices are absolute along the travel range of the motor (e.g., in hydraulic piston applications). The following example code will configure Motor #1 to use ADC channel 1 for the power-on position read as unsigned data with a scale factor of 1: Motor[1].pAbsPos = AdcDemux.ResultLow[0].a; Motor[1].AbsPosFormat = $00000C00; Motor[1].

ACC-36E Manual APPENDIX C: USING POINTERS Below are alternate methods for accessing the data structures of Power PMAC in order to read ADCs on the ACC-36E. Manual ADC Read Using Pointers Following are the necessary steps for implementing the manual ADC read method. The example parameters given here are for an ACC-36E at I/O base address offset $A00000: 1. Point an available M-Variable (12-bit wide) to bits 8-19 of the ACC-36E I/O base address offset, and another to bits 20-31.
