Connecting to Powtran frequency drives
The Powtran model 9130A is used to show WebHMI connection example over RS-485.
The drives have default protocol option that needs to be changed to “1”.
| Pr. 9-05 | 0 - non - standard Modbus (default) |
|---|---|
| 1 - standard Modbus |
With right protocol setting it is possible to control the drive with these parameters:
| Pr. F0.03 | = 9 (Frequency source) |
|---|---|
| Pr. F0.03 | = 2 or 3 or 4 (run/stop source) |
| Modbus register 1000h (HR4096) | Write -10000..+10000 corresponding to -100.00% + 100.00% of rated drive frequency |
| Modbus register 2000h (HR8192) | Write 1 (run forward), 2 (run backward), 6 - stop with deceleration time |
| Modbus register 2001h (HR4097) | Read actual speed |
