Parameter Description
| Code | Description | Setting range | Defaults |
| Pn-00 | The position of the decimal point (the number of decimal places in the displayed value). | 0~6 | 2 |
| Pn-01 | Counting frequency 0-single frequency, 1-double frequency, 2-quadruple frequency | 0~2 | 1 |
| Pn-02 | Counting magnification, after linear calibration, this item will be invalid. | 0.000~9999.999 | 1.000 |
| Pn-03 | The upper limit and the decimal point are defined by settings. | 0~9999999 | 500 |
| Pn-04 | The lower limit and the decimal point are defined by settings. | 0~9999999 | 10 |
| Pn-05 | Counting direction, 0 means positive counting. | 0/1 | 0 |
| Pn-06 | Initial value, this item is an integer without decimal point | 0~9999999 | 0 |
| Pn-07 | Parameter protection password, when it is not zero, the parameter is protected by password. | 0000~9999 | 0000 |
| Pn-08 | The unit of relay reset time is second, 0.0 means no reset. Note 1. | 0.0-999999.9 | 0.0 |
| Pn-09 | Enter the filter coefficient, 0 means no filtering, and level 5 is the strongest. | 0~5 | 0 |
| Pn-10 | 485 communication address, see communication protocol for details. | 00-99 | 01 |
| Pn-11 | Pn-08 is 0 when the lower limit relay action mode, 0-below the lower limit action 1-above the lower limit action, but has nothing to do with the upper limit, 2-over the lower limit action, if the upper limit is reached, it will reset. If Pn-08 is non-zero, this item is invalid. | 0~2 | 0 |
| Pn-12 | The input pulse form selects 0-quadrature code input 1-single input. For single input, both can be connected to AB. | 0 | 0 |
| Pn-13 | 485 serial port baud rate setting 600~9600 bps, Note 2 | 0~5 | 5 |
Speed Parameter
| Code | Description | Setting range | Defaults |
| S n-00 | The position of the decimal point (the number of decimal places in the displayed value). | 0~4 | 2 |
| S n-01 | Speed unit: 0-mm/s 1-mm/min 2-m/h | 0~2 | 0 |
| S n-02 | Speed multiplier, the speed value can be corrected | 0.000~9999.999 | 1.000 |
| S n-03 | The upper limit and the decimal point are defined by settings. | 0~99999 | 300 |
| S n-04 | The lower limit and the decimal point are defined by settings. | 0~99999 | 50 |
| S n-05 | Speed measurement mode. 0 is the instant speed; 1-5 is the speed average time, in seconds. | 0~5 | 0 |
| S n-06 | The reset time unit of the speed relay is second, 0 means no reset, note 1. | ||
| S n-07 | When S n-06 is 0, the lower limit relay action mode is the same as Pn-11. If S n-06 is non-zero, this item is invalid. |
