Modbus control
VFD parameters
In the DZB312 series manual:
- Page 10 (17 in the PDF) gives the parameter list
Here are the ones relevant for Modbus control:
| Function Code | Serial No. | Default Value | Required Value | Description |
|---|---|---|---|---|
| F0.01 | 1 | 1: terminal | 2: RS-485 | run command source |
| F0.03 | 3 | 1: AVI | 6: RS-485 | frequency command source |
| F3.03 | 81 | 0: only keypad | 2: keypad and RS-485 | stop function sources |
| F4.11 | 108 | 0 | ? | fault automatic reset number |
| F4.18 | 115 | 0: keypad (F4.19) | 3: RS-485 | PID setpoint source |
| F4.20 | 117 | 0: reserved | 3: RS-485 | PID feedback source |
| F6.00 | 142 | 1 | RS-485 Modbus slave address | |
| F6.01 | 143 | 3: 9,600 bps | RS-485 Modbus baudrate | |
| F6.02 | 144 | 0: N, 8, 1 | RS-485 Modbus parity/data-width/stop-bits | |
| F6.03 | 145 | 5 | RS-485 Modbus response delay (ms) | |
| F6.04 | 146 | 0.0 (invalid) | 2.0 (2 seconds) | RS-485 Modbus timeout (s) |
| F6.05 | 147 | 1: continue without alarm | 2: stop with alarm (only when in RS-485 mode) | RS-485 Modbus error handling |
| F6.06 | 148 | 0: respond to writes | 0: respond to writes | RS-485 Modbus write response |
Modbus registers
In the DZB300 series manual (which also applies to DZB312 series):
- Page 49 (91 in the PDF) describes the Modbus protocol (should be standards compliant)
- Page 53 (100 in the PDF) has the register address map
| Register No. (hex) | Register No. (dec) | R/W | Value | Description |
|---|---|---|---|---|
| 0x1000 | 4096 | R/W | 1-8 (look in manual) | Modbus controlled command |
| 0x1001 | 4097 | R | 1-4 | inverter state |
| 0x2000 | 8192 | R/W ? | -10000 - +100000 (frequency/PID percentage * 100) | frequency/PID setpoint percentage (?) |
| 0x3000 | 12288 | R | (decimal Hz * 10) | frequency setpoint |
| 0x3001 | 12289 | R | (decimal Hz * 10) | output frequency |
| 0x3002 | 12290 | R | ??? | output current |
| 0x3003 | 12291 | R | (decimal V) | output voltage |
| 0x3004 | 12292 | R | ??? | output speed |
| 0x3005 | 12293 | R | ??? | output power |
| 0x3006 | 12294 | R | output torque | |
| 0x3007 | 12295 | R | (decimal V * 10) | DC bus voltage |
| 0x5000 | 20480 | R | ??? | inverter fault address |
| 0x5001 | 20481 | R | 0-8 (look in manual) | Modbus communication fault |
