Tachometer Input Mode (tinm) Set the count input mode to one of the following: 1 input (F1), 2 inputs (F2), error (F3), absolute ratio (F4), or error ratio (F5). Input mode 1 input 2 inputs Input Count 1 Internal processing None Application Operation with only one input. Measuring the difference between two inputs (error in number of revolutions). Measuring the ratio of error for two inputs (measuring the error ratio of number of revolutions). N: Number of pulses per revolution d: Diameter of rotating body (m) d: Circumference (m) d: Diameter of rotating body (m) Counts 1 and 2 None Count 1 input - Count 2 input Count 1 input ÷ Count 2 input Error Counts 1 and 2 · Observe the following points when setting a prescale value. Set the set value to a value less than {Maximum countable value - Prescale value}. Example: If the prescale value is 1. 25 and the counting range is 0. 000 to 999. 999, set the set value to a value less than 998. 749 (= 999. 999 - 1. 25). If the set value is set to a value greater than this, output will not turn ON. * Output will turn ON, however, if a present value overflow occurs (FFFFFF or FFFF}. Absolute ratio Counts 1 and 2 (Count 1 input - Error ratio Counts 1 and 2 Count 2 input) ÷ Count 2 input Note: If the prescale value setting is incorrect, a counting error will occur. Check that the settings are correct before using this function. Averaging Method (avgt) (Only for Tachometer Operation) A simple average or moving average can be selected for the averaging. With the moving average method, the average of the measurement values is displayed each sampling cycle, in contrast to a simple average, with which the the average of the set number of samples is displayed. Tachometer Output Mode (totm) Set the output method for control output based on the comparison value. Upper and lower limit (HI-LO), area (AREA), upper limit (HI-HI), and lower limit (LO-LO) can be set. (For details on the output modes, refer to Output Mode Settings and Operation on page page 34. ) Number of Averaging Times (avgn) Flickering display and output chattering can be prevented using average processing. Average processing can be set to one of four levels: no average processing, 2 times (i. e. , the average of 2 measurement values), 4 times, 8 times, or 16 times. The measurement cycle will be equal to the sampling cycle multiplied by the average processing setting (i. e. , the number of times). [. . . ] Unexpected operation resulting in property damage or accidents may occur if the settings are not appropriate. · Do not leave the Counter for long periods at a high temperature with output current in the ON state. Doing so may result in the premature deterioration of internal components (e. g. , electrolytic capacitors). · EEPROM is used as backup memory when the power is interrupted. [. . . ]
