13. the MR330 Controller via a duplex 62 5 125um optical fiber link The MR330 Controller constantly probes the sensor by sending a short optical pulse to the sensor The sensor modulates the optical spectrum of that light pulse depending on the current sensor position The MR330 controller receives this modulated optical signal and calculates the position The system is a Single Turn Absolute position sensor However the controller provides mechanism to use the system as a quasi multi turn position sensor Figure 6 shows the functional blocks to which the user interfaces This block diagram does not show the details of the sophisticated optical measurements and algorithms employed to extract the position information The default single turn resolution is 13 bits can be set to 14 bits 39850 counts via ZAPPY configuration software and there is also a 12 bit turn counter which keeps track of the full turns of the sensor while the unit powered up and the sensor is connected with the fiber optic link Both absolute single turn position 13 bits and the turn counter 12bits are combined to provide a 25 bit position signal The user has the option to mask the turn counter and thus limit the output to match the physical setup If the sensor is only used to measure a range over let s say 5 turns then the user may limit the turn counter to 3bits providing a range of maximum 8 turns until the output wraps around back to zero Using the example above
14. 1 Voltage Output Page 21 of 62 MICRONOR INC MR330 Fiber Optic Position Sensor System MODE 2 lets the user program the output voltage based on a scale value The output is O when the position is O and will reach 1 when the position reaches the scale value The full 25 bit range is available for scaling When setting this mode up the user should also take into account what should happen when the position reaches maximum or minimum values The MR330 system determines the wrap around point based on the available position range which is based on the turn mask setting n Figure 11 Mode 2 Voltage Output The Countmax is then 2 m Wrap Countmax Scale 2 The wrap point Pwis determined based on the formula above Essentially it is the midpoint between the un used range Scale MODE 3 is very similar to mode 2 but it makes use of the negative output voltage capability of the MR330 The output voltage follows the position output with O position being 10V and when the Scale value is reached the output is OV and with position twice the scale value the output is 10V Mode 3 is ideal when the voltage should swing positive or negative around a predetermined home position In that case the Reset Value of the MR330 should be set to the same value as the scale When the sensor is in the home position that is then equal to the scale value and the voltage output will be OV When the senor turns CCW th

16. A better method is to use a Battery backup and keep the unit powered up even over prolonged power outages The MR330 Controller has a dedicated 12V battery input Connect a 12V sealed lead acid battery of 1Ah or higher capacity between J1 7 BBAT and GND several connection points provided When the supply voltage is removed the 12V battery will keep powering the unit Current draw is approximately 80mA A typical sealed lead acid battery with 3Ah will keep the controller alive for some 38 hours There is a 10mA trickle charge provided from the MR330 controller as long as the regular 24V is applied 3 9 SSI Interface The MR330 Controller communicates the position information as an SSI SLAVE to the servo controller or similar devices The SSI master supplies the clock within the range of 25kBaud to 25O0kBaud clock speed and toggles out 25 bits from the MR330 Controller Resistor CLOCK Figure SSI Interface Connector 12 10 pin The SSI interface is configured as Slave and the master must supply the clock The clock maybe in the range from 25kHz to 250kHz The user should also set the MR330 with the appropriate clock rate This will allow the MR330 to provide correct timing for repeat read mode on the SSI bus If not sure how to set the SSI baud rate leave it at the lowest setting of 25k baud this setting will work fine in most applications Page 19 of 62 MICRONOR INC MR330 Fiber Optic Position
