| Product | FP7 High-speed Counter Units |
| Part Number | AFP7HSC4T |
| Product name | FP7 High-speed Counter |
| Product Number | AFP7HSC4T |
| Input:Insulation method | Photocoupler insulation |
| Input:Rated input voltage | 12 to 24 V DC / 3.5 to 5 V DC |
| Count function:Counter type | Linear counter / Ring counter |
| Count function:External I/O | Control signal input: 8 points (2 points/ch), External output: 8 points (2 points/ch) |
| Count function:Input signal | Phases A, B and Z |
| Input:Input impedance:5 V DC | 390 Ohm (5 V DC) approx. |
| Count function:Counting range | Signed 32-bit (-2,147,483,648 to +2,147,483,647) |
| Input:Input impedance:24 V DC | 3.0 kOhm approx. |
| Count function:No. of counters | 4ch |
| Input:Usage voltage range:5 V DC | 3.5 to 5.25 V DC |
| Other functions:Capture function | Acquires the current count value from the edges of input signals, and stores it in the capture 0 register or capture 1 register. The value of the specified capture register will be overwritten by a new value and the old value will be discarded every time a counter value is captured. |
| Count function:Counter input type | Individual input (Phases A and B): 1 multiple, 2-multipleDirection discrimination input: 1 multiple, 2-multiple2-phase input: 1 multiple, 2-multiple, 4-multiple |
| Input:Input time constant setting | None, 0.1 micro s, 0.2 micro s, 0.5 micro s, 1.0 micro s, 2.0 micro s and 10.0 micro s |
| Input:Usage voltage range:24 V DC | 10.8 to 26.4 V DC |
| Count function:Max. input frequency | 4 MHz / 8 MHz for individual input (phases A and B) (Duty ratio 50 plus or minus 10 %), 4 MHz / 8 MHz for direction discrimination input (Duty ratio 50 plus or minus 10 %), 4 MHz / 8 MHz /16 MHz for 2-phase input (Duty ratio 50 plus or minus 10 %, Phase shifting below 5 %) |
| Other functions:Interrupt input function | Available (2 points/ch, Max. 8 points/unit)(Note) The interrupt input function can be used for 8 points per unit and for a maximum of 8 units (max. 64 points) in the whole system. However, the entire scan time slows down as more interrupt programs are used. Minimize the use of interrupt programs.(Note) The priority order for interrupt inputs is as follows; In a unit, from the smallest interrupt bit. In the whole system, from the smallest unit number. |
| Input:Min. ON voltage / Min. ON current:5 V DC | 3.0 V DC / 4 mA |
| Comparison function:Target value match function | Depending on the count direction, sets or resets the output when the counter value reaches the target value. |
| Input:Min. ON voltage / Min. ON current:24 V DC | 10 V DC / 4 mA |
| Input:Max. OFF voltage / Max. OFF current:5 V DC | 1.0 V DC / 0.5 mA |
| External output:Comparison result output function | Outputs the result of comparison function. |
| Input:Max. OFF voltage / Max. OFF current:24 V DC | 2.0 V DC / 2 mA |
| Measurement function:Frequency measurement function | Measures the intervals between the variations of count values, and calculates the frequency. |
