User manual OMRON H7CX-N DATASHEET

[. . . ] New Product Multifunction Counter/Tachometer H7CX-@-N Ultra-compact Counter Provides More Complete Functionality. Basic Features · Short body with depth of only 59 mm (for 12 to 24-VDC Models with Screw Terminals). *1 · Better readability with character height of 12 mm on 4-digit models and 10 mm on 6-digit models. · The present value display characters can be switched between red, green, and orange. *2 Safety and Reliability · New set value limit and counter functions have been added. Other Features · Front Panel can be changed to white or light gray. *3 · Models with two independent tachometer inputs have been added to the series. *1. For 100 to 240-VAC Models with Screw Terminals: 78 mm, Models with Sockets: 63. 7 mm (case dimension). *2. The H7CX-A11 and H7CX-R11 have only red characters. *3. The Front Panel can be replaced with an optional Front Panel (except for Tachometer-only Models).

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 two inputs (ratio of 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). Average processing enables stable displays even for fluctuating input signals. Set the optimum number of times for the application. Counting Speed (cnts) Set the maximum counting speed (30 Hz/10 kHz) for CP1 input. If contacts are used for input signals, set the counting speed to 30 Hz. Processing to eliminate chattering is performed for this setting. Decimal Point Position (dp) Decide the decimal point position for the measurement value, OUT1 set value, and OUT2 set value. Prescale Value (pscl) It is possible to display the rate of rotation or the speed of a device or machine to which the H7CX is mounted by converting input pulses to a desired unit. If this prescaling function is not used, the input frequency (Hz) will be displayed. It is also possible to specify time (seconds) as the display value. [. . . ] The EEPROM is written at the following times: · When the power supply is turned OFF · When switching from Configuration Selection Mode or Function Setting Mode to Run Mode · Dispose of the product according to local ordinances as they apply. 53 MEMO 54 Warranty and Application Considerations Read and Understand This Catalog Please read and understand this catalog before purchasing the products.
