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. | |
