MELSEC-F Series High-Speed Counter Specifications
FX3U-2HC
FX3U-2HC image
- Each unit has two channels of high-speed input terminals and up to 200 kHz high-speed counting is possible. 2-phase counter can count multiplication by 1, by 2, by 4.
- Open collector (5, 12 or 24 V DC) or differential line driver (equivalent to AM26C31) output type encoder or sensor can be connected to the input. 16 or 32-bit counter mode can be selected, and multiplication can be specified to the 2-phase counter.
- The input/output signal connections are made through connectors. Connectors "FX-I/O-CON2-S and FX-I/O-CON2-SA" can be used. (Wiring cable must be provided by customer.)
FX3U-2HC Performance Specifications
| Number of Input Channels | 2 ch | |
|---|---|---|
| Input Format | Open collector, differential line driver (differential line driver output type encoder is connected to the 5 V terminal) | |
| Input Voltage | Selected from 5, 12 or 24 V DC depending on the connection terminal | |
| Maximum Response Frequency | 1-Phase 1 Input | 200 kHz or less |
| 1-Phase 2 Inputs | 200 kHz or less | |
| 2-Phase Input | 200 kHz or less (multiplied by 1), 100 kHz or less (multiplied by 2), 50 kHz or less (multiplied by 4) | |
| Count Range | At 32-bit specification: -2,147,483,648 to +2,147,483,647 At 16-bit specification: 0 to 65,535 (upper limit can be specified with BFM #3, #2, #43, #42) | |
| Count Mode | Automatic up/down (The counting direction of the 1-phase 1 input counter is determined by the following command) [H/W up/down] Counts up/down by OFF/ON of the A-phase input terminal. [S/W up/down] Counts up/down by the current value (K0/K1) of BFM #1, #41. | |
| Matching Output (Comparison) | When the current value of the counter and the comparison setting match, the comparison output is set (ON) within 30 μs, and is cleared (OFF) within 100 μs by the reset command. | |
| Output Format | Open collector output, 2 points, 5 to 24 V DC at 0.5 A each | |
| Display (LED) | øA, øB, DIS, PRE, YH1, YH2, POWER, UP, DOWN | |
| Number of Occupied Inputs/Outputs | 8 points (either input or output can be considered) | |
| Applicable Sequencers | FX5U, FX5UC, FX3U (V2.20 or later), FX3UC (V2.20 or later) "Connection to FX5U or FX5U CPU unit" Connection to FX5U or FX5UC requires FX5-CNV-BUS or FX5-CNV-BUSC. Select either one according to the system configuration. "Connection to connector type sequencer" Connection to FX3UC requires either FX2NC-CNV-IF or FX3UC-1PS-5V. | |
