| Number of I / O occupied points |
8 points (either input or output can be considered) |
| mass |
0.2kg |
| Counting range |
When 32-bit is specified: -2,147,483,648 to +2,147,483,647 When
16-bit is specified: 0 to 65,535 (Upper limit can be specified with BFM # 3, # 2, # 43, # 42) |
| Count mode |
Automatic up / down
(However, the counting direction of the 1-phase 1-input counter is determined by the following command.)
[H / W up / down]
Up / down count is performed by turning OFF / ON of the A-phase input terminal.
[S / W up / down]
Up / down count is performed based on the current value (K0 / K1) of BFM # 1 and # 41. |
| Display (LED) |

| Number of input channels |
2ch |
| Input format |
Open collector, differential line driver
(differential line driver output type encoder is connected to the 5V terminal) |
| Input voltage |
DC5V, DC12V, DC24V can be selected by the connection terminal |
| Maximum response frequency |
1 phase 1 input |
200kHz or less |
| 1 phase 2 inputs |
