Input/Output Functions ■ INPUTS CP1/CP2 (count inputs) Reset Key protect • Count signal inputs. • Up, Down, and Reversible (command, individual, or phase difference) inputs accepted. • Maximum counting speed: 5 kcps. • Present value reset (to zero in Up or Up/Down modes, to preset with 1-stage models in Down mode and to preset 2 for 2-stage models in Down mode). • Count inputs are not acknowledged while reset input is ON. • Reset indicator lit while reset input is ON. • Reset, Right Shift and Up keys are inoperative while key protect input is ON. • Although Display key remains effective, only monitoring of settings is possible. • Keys protected indicator lit while key protect input is ON. • Effective when power supply is turned off. Count Input vs. Reset Input When the RESET input is ON or the RESET key input is ON, the count input is prohibited and the present value is reset. However, when the key protect input is ON and the key protect level is KP-2 or KP-4, no RESET key input is accepted. Reset Time Set to 1 ms if high-speed resetting is necessary. Set the reset time to 20 ms if you need to prevent false signals caused by electrical noise from affecting the counter. ■ OUTPUTS Outputs 1 and 2 Outputs made according to designated output mode when corresponding preset is reached. Using Prescale Function The prescale function converts the number of input counts into a user-selectable value. The example below shows a system that uses 250 encoder pulses to determine when an object has advanced 0.5 meters. Here is how to convert pulses into a unit of measure appropriate for your application: 1. Set the decimal point between the third and fourth digits. 2. Set a prescale value of 0.002. This is calculated by dividing the unit of measure (0.5) by the number of pulse counts (250). 7 H7CR H7CR Timing Charts ■ INPUT MODES Up Count input CP1 H L Gate input CP2 H L Down Count H input L CP1 5 4 Gate input CP2 H L n n-1 3 n-2 2 n-3 Count 1 Count n-4 n-5 0 Count input CP1 H L Gate input CP2 H L Count H input L CP1 5 Gate input CP2 H L n n-1 4 n-2 3 n-3 2 Count 1 0 Reversible A (command inputs) CP1 n-4 Count n-5 0 0 Reversible C (phase difference inputs) CP1 See below.

The settings that are possible for each model vary. After changing modes, the counter is ready to accept setting changes to default items. Run Mode Item Applicable Counters Preset 1, H7CR-B, H7CR-SB Preset 2 H7CR-C, H7CR-SC set value Description Setting values Determine the timing of the outputs in comparison to the present count value according to the output mode. The DISPLAY key switches between set value 1 and 2 in double preset models. Use the increment keys (1 to 6) to change a digit. Sequence when changing a digit using the increment keys (1 to 6). Minus sign displayed for leftmost digit of H7CR-C and H7CR-SC (+/– range counters) by using increment key 6. Setting Mode Item Input mode (default) Applicable Counters H7CR-A, H7CR-SA H7CR-B, H7CR-SB H7CR-C, H7CR-SC H7CR-8, H7CR-11 Description Setting values Determines the input mode: Increment keys 1 to 6 change the display. Up, Down, Reversible A, Reversible B, Reversible C Press the Up key until the desired Up Down Reversible A Reversible B Reversible C mode is displayed. *There is no Up or Down mode for H7CR-C and H7CR-SC (+/– range) counters. Output mode and OUT 2 output time H7CR-A, H7CR-SA H7CR-B, H7CR-SB H7CR-C, H7CR-SC H7CR-8, H7CR-11 Determines the operation of the control outputs. Refer to "Output Operations" tables for details. Also determines the output time for control output (OUT2) in single preset counters. Increment keys 1 to 6 change output mode. OUT 1 output time H7CR-B, H7CR-SB H7CR-C, H7CR-SC (double preset models only) Designates the output time for output 1 (double preset models only). Press the increment keys to set the desired time for output 1. Increment keys 1 to 6 change output time. *Hold mode is available only on H7CR-BW and H7CR-SBW counters. (Applicable to output modes C, R, K, P, Q, and A only.) Counting speed H7CR-A, H7CR-SA H7CR-B, H7CR-SB H7CR-C, H7CR-SC H7CR-8, H7CR-11 Changes the input filter for counting inputs. Used to prevent counting errors caused by input interference. Press the increment keys to set the desired speed. A "k" on the display indicates kilocycles (1000 cycles). Increment keys 1 to 6 change count speed. Minimum reset times H7CR-B, H7CR-SB H7CR-C, H7CR-SC H7CR-8, H7CR-11 Determines the minimum time required for the reset input. Press any increment key to switch between 1 and 20 ms. Increment keys 1 to 6 change reset time. 1 ms 20 ms Note: Settings changed in the Setting mode are effective only after returning to the Run mode. 21 H7CR H7CR Setting Mode continued Item Applicable Counters Description Setting values Decimal point H7CR-B, H7CR-SB H7CR-C, H7CR-SC H7CR-8, H7CR-11 Determines the position of the decimal point on the display. Press the Increment keys 1 to 6 to move the decimal from left to right. Increment keys 1 to 6 move decimal point. Scale factor H7CR-B, H7CR-SB H7CR-C, H7CR-SC H7CR-8, H7CR-11 Used to convert counts to other units, (e.g., to display millimeters when each input pulse represents 0.02 mm, input a scale factor of 0.02). Values from 0.001 to 99.999 are possible. Press the Increment keys to set the desired value. Increment keys 1 to 5 change the scaling Key protection level H7CR-B, H7CR-SB H7CR-C, H7CR-SC H7CR-11 Blocks certain keys to prevent accidental operation. The key protection level, kP-1 to kP-4, determines which keys are locked out when the key protection input is ON. The locked keys are crossed out in the diagrams at right. Increment keys 1 to 4 change key protection level. Note: Settings changed in the Setting mode are effective only after returning to the Run mode. ■ EXAMPLES Run Mode Changing the Set Value When changing the set value while the counter is operating, an output will be produced if the set value ever equals the present value. To avoid triggering the output, begin by setting a higher digit to a larger number. Output Delay The following table shows the delay from when the present value passes the set value until the output is produced. The delay is the result of output control time, signal transmission time, relay switching time etc. 1. Press the DISPLAY key to change the displayed values for preset 1 and 2 during operation. Actual measurements in N and K modes: Control output Contact OUT1, OUT2 Transistor OUT1, OUT2 Max. counting speed 30 cps 1 kcps 5 kcps 30 cps 1 kcps 5 kcps Output delay* 18 to 24 ms 4.7 to 5.8 ms 4.4 to 5.4 ms 13.5 to 20 ms 0.59 to 0.81 ms 0.29 to 0.44 ms * The variation in delays is due to different modes and conditions. For systems where the delay is a problem, take actual measurements under operating conditions. 2. Change the set value from 250 to 1,250. Pressing increment keys 1 to 6 advances the corresponding column value by 1. Nonsignificant zeros are not normally shown on the set value display. 22 H7CR H7CR Setting Mode Changing Setting in the Function Setting Mode 1. Press the MODE key to switch from RUN mode to SETTING mode. 3. Changing the counting speed or another selected item: Press the MODE key until the desired item appears. The counter will continue operation if switched from RUN mode to function setting mode during operation. Change the item setting by pressing increment keys 1 to 6. The MODE key will be locked if the key protection function is enabled. Settings changed in the function setting mode are not effective until RUN mode is entered. As the operating conditions will change in this case, always reset operation with the RESET key or a reset input. 2. Press the MODE key to scroll successively through the items that can be set. Release the MODE key to select the desired item. Press the DISPLAY key to return to RUN mode from SETTING mode. Precautions ■ EXTERNAL POWER SUPPLY The capacity of the counter's external power supply is 50 mA at 24 VDC or 100 mA at 12 VDC. For models with 24 VAC/12 to 24 VDC specifications, loads must be established between the following limits. Load (mA DC) 100 12 VDC 50 24 VDC 20 10 0 10 15 20 25 Supply voltage (VDC) 23 H7CR H7CR ■ POWER SUPPLY When the power turns OFF then ON, the input signal may or may not be received. The diagram below shows when the input signal will be received, will not be received or will be unstable. The unstable period will vary with power supply voltage, and the load conditions on external power supplies. For 100 to 240 VAC and 24 VAC/12 to 24 VDC counters, be sure that the capacity of the external power supply is adequate, because the power supply may not provide a surge current sufficient to start the counter due to the switching regulator contained in the counter's internal circuitry. Power supply Connect the power supply voltage through a relay or switch in such a way that the voltage reaches a fixed value immediately. On Off 0 to 50 ms Input Not received 10 ms 0 to 0.9 s Received Not received Unstable ■ TRANSISTOR OUTPUT The transistor output in H7CR counters is optically isolated from the internal circuitry by a photocoupler, so either NPN or PNP output is possible. ■ SELF DIAGNOSTIC FUNCTIONS The displays at right appear when irregularities occur. When the problems causing these conditions have been cleared, the preset count value and all outputs will be reset in the same way as when the Reset key is pressed. Display –––– Meaning Present value below minimum FFFFFF Present value above maximum E1 CPU error E2 Memory error – – – –: FFFFFF: Outputs Recovery Not Press RESET key changed. for 1 second or reset input. OFF Press RESET key for 1 second. Displayed for +/– range counters H7CR-C and H7CR-SC when max. negative value is exceeded. Displayed for +/– range counters H7CR-C and H7CR-SC when max. positive value is exceeded. ■ OPERATING ENVIRONMENT Although the front of the counter resists water and oils and can be used where subject to these, extended exposure to large amounts of either can adversely affect internal components. The counter, input signal lines, and the input device must be separated as far as possible from any sources of electrical noise, such as high-voltage power lines. Shielded input signal lines can also be effective in suppressing noise. To prevent damage, the exterior of the counter must not be exposed to organic solvents (e.g., paint thinner or benzene), strong alkalis, or strong acids. ■ OTHER Always isolate the counter from external circuits or short all terminals before measuring dielectric strength between electric circuits and non-charged metal parts or performing similar testing with the counter mounted in a control panel. This is to prevent internal circuit damage that might occur if the test voltage enters the counter interior due to withstand-voltage or insulation failure in control panel devices. 24 The counter contains a lithium battery, and must never be incinerated. Dispose of the counter as a noncombustible item. H7CR H7CR Applications of Operating Modes ■ SINGLE OPERATING MODES ■ REPETITIVE OPERATING MODES Single operating modes are basic modes, among which, Mode N is the most basic (input the RESET signal to restart). Modes R and C are typical of repetitive operating modes (the counter internally resets itself after each counting operation and then restarts). The counter begins the next counting operation after the present output is processed. Mode N The displayed count-up value is on hold. Mode R The displayed count-up value is on hold. Example: Cutting Objects to Specified Size The object is advanced for a specified distance measured by encoder pulses to determine correct length for cutting. Example: Portion Control of Material or Ingredients The valve is closed when the supplied quantity of cookie batter or blended ingredient has reached a specified amount. Wood Cutter control Cookie batter Valve opening/ closing Rotary encoder Counter Rotary encoder Programmable controller Counter Mode A Select Mode A for a one-shot output of the count-up signal used in Mode N. The displayed count-up value is on hold. Mode A can be used for a start signal for sequence control equipment. Mode F Go to Mode F to monitor the number of overrun objects. The process value is displayed normally. It is possible to monitor the number of overrun objects upon interruption of the operation after a specified number of objects are counted. Mode Q Choose Mode Q to view the process value continuously. There is no difference in operation between Mode R and Mode Q. Mode C The counting operation restarts upon counting up. The process value is displayed continuously. Example: Marking Material at Regular Intervals A roll of film being advanced is marked at regular intervals based on encoder input. Ink Mode K Select Mode K for the one-shot output of the count-up signal used in Mode F. Mode K can be used as a start signal for sequence control equipment. Rotary encoder Counter Mode P Choose Mode P to put the count-up value on hold (display is on hold while the one-shot output is ON). There is no difference in operation between Mode C and Mode P. 25 H7CR H7CR NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters to inches, divide by 25.4. Omron Europe B.V.
