THE ABSOLUTE DIGITAL DURACODER

Absolute Digital DuraCoder Overview

DuraCoders are designed as direct replacements for optical encoders. Instead of being designed around a disk and optics, a DuraCoder uses a resolver as its primary shaft position sensor. Constructed in a manner similar to high precision motors, resolvers are absolute, single turn position sensors that are unsurpassed in terms of ruggedness and reliability. The resolver is an analog device whose outputs vary sinusodially as the shaft is rotated. If you are interested in learning more about resolvers, read the article on our website at: https://www.amci.com/indus-

trial-automation-resources/plc-automation-tutorials/whatresolver/.

The resolver’s analog signals are decoded into a 12 bit position value by electronics incorporated into the DuraCoder. This 12 bit (4096 count), absolute position value is available as a paral lel digital output. Several different output codes and voltage level outputs are available.

In addition to the actual position outputs, the Absolute Digital DuraCoders also offer two inputs that control the outputs. The Latch Input is used to control when the position values update and the Direction Input controls the direction of rotation needed to produce increasing counts.

The Absolute Digital DuraCoder is available in a variety of industry standard size 25 optical encoder packages. A flange mount unit with a 3/8" shaft and a side connector is shown in figure R1.1. Servo mount and end connect units are also available. If your application requires you to mount the DuraCoder to a motor, a blind shaft mounting option is available as well. Finally, a face mount unit with a 5/8 inch shaft is available for applications that may be exposed to high shaft loads.

Outline drawings of all of the packing options is available in the Outline Drawings section of the Installation chapter, starting on page 11.

Absolute Digital DuraCoder Diagnostics

Starting in August of 2018, Absolute Digital DuraCoders include additional diagnostic features.

 Fault Output - This output is active during normal operation and goes inactive when one or more of the

following conditions exists:

1) Over temperature of the output drivers

2) Output shorted to ground

3) Output shorted to Vdc

4) Open connection or wire.

 Test Input - Used to test the outputs of the unit. This single input can be used to force all of the outputs

into their active or inactive states. A full explanation of the uses of this pin can be found in Task 2,

Diagnostics starting on page 21.

 Status LED - Located on the back of the unit, this LED shows the status of the unit under normal oper-

ating conditions, and the status of the outputs when used with the Test Pin.

Description of Outputs

Output Codecs

The Absolute Digital DuraCoder can output its data in 12 bit Natural Binary , 12 bit Gray Code, or 12 bit BCD formats. In Natural Binary and Gray Code formats, the maximum output value is 4,095. For BCD format, the maximum output value is 999.

to DuraCoder Input Voltage.

Output Update Control

Position data updates are controlled by a single pin named Latch Control and the type of control is set when the DuraCoder is ordered. Two types of position update control are available.

In new installations, the sole advantage of Gray Code over Natural Binary is that only one bit changes per count. This allows you to easily check the validity of the position data. This one bit change holds true only if your number of counts per turn is a power of two. (2, 4, 8, ... 4,096) If your number of counts per turn is not set to a power of two, the transition between your maximum count and zero will result in two or more bits changing in the data.

 Level Sensitive (Part # starts: DC25?-??A) – The

position data updates every 325 microseconds while the Latch Control pin is at a Logic 1 voltage or the pin is left open. The position data will freeze within 25 microseconds of this pin being driven to a Logic 0 voltage. The position data will begin to update within 325 microseconds once it is released from the Logic 0 voltage level. If the Latch Control pin is at a Logic 0 on power up, all outputs will be in their zero state until the first positive transition. Position data will not be valid until this transition.

Shaft Loading

Limit shaft loading to the following values. These values statistically yield an L10 life of 2X109 revolutions. (L10 life is a rating which means that statistically, only 10% of the bearings will have failed after 2X10 olutions.) Shaft loading has an exponential effect on bearing life. The bearings will statistically last longer if you can limit shaft loading below the given values. Consider using the 5/8" shaft DuraCoder from AMCI if your shaft loading is expected to be greater than the values given below. Outline drawings for the 5/8" shaft DuraCoders start on page

Shaft Loading

The load that the Analog DuraCoder presents to your input shaft, which is equal to the load presented to the DuraCoder by your input shaft, is difficult to calculate and is dependent on the accuracy of the mounting. The flexible metal mounting bracket will be able to absorb most of the radial loading forces, but accurate mount ing of the DuraCoder is still important.

Connector Pinout

Figure T1.11 shows the pin designations on the MS3112E-14-19P connector. AMCI sells a straight mating connector under the AMCI part number: MS-19.

AMCI does not supply factory made cables for the Absolute Digital DuraCoder because of the many possible configurations.

Pins A-M: Position Output – These pins output the absolute position value.

Pin A is the least significant bit.

INSTALLATION

rev-

Pin N: Error Output – The output state of this pin is active dur-

ing normal operation. It switches to its inactive state when there is a fault condition. The four detectable fault conditions are:

 Output driver over -temp erature  Output shorted to ground  Output shorted to Vdc  Open wire or connections

20 Gear Drive, Plymouth Ind. Park, Terryville, CT 06786 Tel: (860) 585-1254 Fax: (860) 584-1973 http://www.amci.com

These faults are latched. Once they occur, the DuraCoder will report the error until it is cleared. There are two methods to clear the error.

1)Cycle power to the DuraCoder

2)Pull the Test input low for a minimum of 10 milliseconds and release it.

If the fault condition no longer exists, the Error output will return to its active and the Status LED on the back of the unit will change from red to green.

See table T2.2, Output Voltage States, found on page 21 for the output voltage levels when the output is active or inactive.

Pin P: Test Input – This pin is used to test the outputs of the

DuraCoder and clear fault conditions. This pin should be left open for normal operation. Connecting this pin to GND will place the DuraCoder in test mode. The use of this pin is fully described in Task

Prior to the August 2018 release of the Absolute Digital DuraCoder, the “N” and “P” pins were “No Connection” pins.

2, Diagnostics, starting on page 21.

INSTALLATION

Connector Pinout

Pin R: Direction Control – This pin controls which direction the shaft must rotate to increment the position

data. With this pin open circuit, position data increases with CCW rotation, looking at the shaft. Connecting this pin to Pin T, (DC Return), forces the position to increase with CW rotation, looking at the shaft.

If you want CW increasing counts, you must connect pins R and T at the connector or at the end of a short extension cable. Do not run a long cable pair from these pins and connect these pins at the other end of the cable. This may allow noise to be injected into the Direction Con trol pin that will affect the position count.

Pin S: Case GND – This pin should be used to tie the body of the DuraCoder to chassis ground at the



DuraCoder if the unit is not grounded through its mounting. This pin is not to be used as the power supply return. The power supply must be wired to pins T (DC Return) and V (+DC Input).

Pin T : DC Return – This pin must be connected the power supply return. The power supply must be wired to

pins T (DC Return) and V (+DC Input). This pin cannot be used to tie the body of the DuraCoder to chassis ground.

Pin U: Latch Control – The Latch Control input is fully described in the section Output Update Control,

found on page 8. Briefly here, there are two types of position data update control:



Level Sensitive:

The outputs update every 325 microseconds when the pin is open circuit or at a logic 1 voltage level. The outputs will freeze within 25 microseconds when a logic 0 voltage is applied. Wh en the input transitions between a logic 0 and a logic 1, the outputs will take approximately 325 microseconds before they begin to update.



Edge Sensitive:

The outputs update within 325 microseconds of a 01 or 10 transition on the input. The outputs then freeze until another valid transition. T r ansitions must be at least 325 micro seconds apart, which yields a maximum frequency of 1.5KHz with a 50% duty cycle. All of the outputs will be at a logic 0 state on power up until the first valid transition occurs.

Pin V: +DC Input – This pin must be connected to the high side of the power supply. The power supply must

be wired to pins T (DC Return) and V (+DC Input).

This chapter is specifically for the latest revision of the Absolute Digital DuraCoders that contain additional diagnostic features. These instructions only apply to units with a status LED on the rear cover.

Output States

The Absolute Digital DuraCoder offers both sinking and sourcing outputs. Therefore, these diagnostic instructions list the outputs as being in their active state or inactive state. (Conducting current, or not conduct ing current.) T able T2.1 below shows the expected output voltages when an output is in its two states. Refer to

Part Numbering System, found on page 8 if you need to determine the type of outputs your DuraCoder has.

Over Voltage and Under Voltage Detection

The output driver IC on the DuraCoder has the ability to detect over voltage and under voltage conditions on the power supply and turn off the drivers if either condition occurs. This leaves the outputs in a known state instead of an uncertain state based on the power supply levels. However, this is a feature of the driver IC itself, and does not indicate to the DuraCoder that it is in this state.

Therefore, if the outputs are in their inactive state but the DuraCoder does not give any fault indication, check the power supply voltage and verify that it is within its acceptable range of

Error Output

The Error output is the same driver type as the position outputs, with an internal pull-up or pull-down resistor. Therefore, the “high” voltage is equal to the voltage that powers the DuraCoder.

The output can sink or source a maximum of 500 milliamperes. It is designed to drive a typical PLC DC input. Figure

Input

Module Common

For sinking output units, the output is low during normal operation. For sourci ng output units, the output is high for normal operations. The output switches to its inactive state when one of the following conditions occurs:

 Over temperature fault on the output driver IC.  One or more outputs shorted to ground.  One or more outputs shorted to the input voltage of the DuraCoder.  One or more outputs with an open connection or broken wire.

These faults are latched. Once they occur , the DuraCoder will report the error until it is cleared. There are two methods to clear the error.

1) Cycle power to the DuraCoder

2) Pull the Test input (Pin P) low for a minimum of 10 milliseconds and release it.

If the fault condition no longer exists, the Error output will return to its active state and the Status LED on the back of the unit will change from red to green.

Test Inp ut

The Test input is a DC input with an internal pull-up resistor to the supply voltage of the DuraCoder. When the Test input is pulled low for a minimum of 325 microseconds, the DuraCoder is placed in test mode. The unit remains in test mode while the Test input is low. Once the Test input is released, the DuraCoder will return to its normal mode of operation within 325 microseconds.

If there are no faults, the state of the outputs is determined by the DuraCoder shaft position. If there is an overtemperature fault, all of the outputs are forced into their inactive state. For all other fault conditions, the state of the unaffected outputs is determined by the DuraCoder shaft position.

section above for a list of detectable

Test Input (continued)

Test Mode (Test Pin Tied to GND)

In T est mode, all of the outputs are forced into their active or inactive states. This is accomplished by pulling the Test input low for a minimum of 325 milliseconds. The DuraCoder remembers the last state the outputs were forced into. Once the T est input is released for a minimum of 325 milliseconds and pulled low again, the outputs will switch to their other test state. When the Test input is released for a minimum of 325 millisec onds, the unit exits Test Mode, and the outputs begin to output position data again.

Testing Sourcing Output DuraCoders

A pull down resistor or equivalent load is required when testing sourcing outputs. If this load is not present, a voltmeter may read that the output is active when it is in its inactive, high impedance, state due to leakage current through the output.

High True Output Units

High True output units have the output at 0 Vdc for a logic “0” and +Vdc for a logic “1”.

 If the Test Pin in pulled low when power is applied to the unit, all outputs are set to 0 Vdc. The drivers

are not conducting and this is considered a logic “0”.

1) If the Test Pin is high or open during power up, the first time it is pulled low for greater than 325 milliseconds, all outputs are set to the +Vdc voltage. The drivers are conducting and this is considered a logic “1”. If the output voltage is at 0 Vdc, you have a short to ground or a wiring error.

2) Releasing the Test Input for more than 325 milliseconds will take the unit out of test mode and back to normal operation.

3) Pulling the Test Input low for greater than 325 milliseconds will place the unit back into test mode. All of the outputs are now set to 0 Vdc. The drivers are not conducting and this is considered a logic “0”. If the output voltage is at +Vdc, you have a short to +Vdc or a wiring error.

4) Releasing the Test Input for more than 325 milliseconds will take the unit out of test mode and back to normal operation.

Repeating steps 1 through 4 will force the outputs to alternate between their logic “1” and “0” states.

DIAGNOSTICS

Testing Sinking Output DuraCoders

If the unit does not have internal pull up resistors, external pull up resistors or equivalent loads are required when testing sinking outputs. If this load is not present, a voltmeter may read that the output is active when it is in its inactive, high impedance, state due to leakage current through the output.

When the unit has internal pull up resistors, the voltage on the outputs will be equal to +Vdc. When external pull up resistors are used, the pull up voltage on those resistors does not have to be the same as +Vdc. For example, the DuraCoder can be powered by 24 Vdc, while the pull up resistors have 12 Vdc, or 5 Vdc, as their supply voltage. For simplicity in the explanations that follow, “+Vdc” will be used to describe the voltage on the pull up resistors.

High True Output Units

High True output units have the output at 0 Vdc for a logic “0” and +Vdc for a logic “1”.

 If the Test Pin in pulled low when power is applied to the unit, all outputs are set to 0 Vdc. The drivers
