The address of the I/O tag is a 16-bit number (1-65535). It can be entered decimally (e.g. 1 or 1234) or hexadecimally using a hash (e.g. #0001 or #4D2).
A special symbolic address STATUS is also supported, which indicates the inverter status register in the form of an integer variable (for the meaning of individual bits, see Table 2).
Table 2 - Status register of a converter
| Bit | Meaning | Logical 0 | Logical 1 |
|---|---|---|---|
| 0 | Motor voltage | disconnected | connected |
1 | Converter is ready for START via serial link | not ready | ready |
| 2 | Converter is reset via serial link | OFF | ON |
| 3 | Reverse - required frequency or position is negative | OFF | ON |
| 4 | Motor ready | not ready | ready |
| 5 | Active set | SET1 | SET2 |
| 6 | Converter is reset | OFF | ON |
| 7 | Terminal switch 2 | not ready | ready |
| 8 | Fault | didn’t occur | occurred |
| 9 | Warning | didn’t occur | occurred |
| 10 | Start / Stop | in stop | in start |
| 11 | End of trial operation | OFF | ON |
| 12 | Critical warning | didn’t occur | occurred |
| 13 | Frequency change at the output of ramp generator | not finished | finished |
| 14 | Position calibration command | not received | received |
| 15 | Password authorization | not valid | valid |

If the number is fractional, the corresponding linear conversion must be entered in the I/O tag configuration in the Conversion tab (e.g. coefficient A=0.1 for #0030, A=0.01 for #0028).

Warnings register 1 (values of the I/O tag with address #0045). If an arbitrary bit is set to logical 1, the converter generates a corresponding warning.
| Bit | Meaning |
|---|---|
| 0 | some warnings W1-W5: |
| 1 | W6 - Motor cooler has reached an increased temperature (over 75 °C). For VQFREM 400 005, 007, and 011 types, the module temperature is over 90 °C |
| 2 | W7 - The converter switches itself into scalar mode due to IRC/ARC failure. |
| 3 | W8 - Signalisation of reverse direction of IRC/ARC. |
| 4 | F7 - The time needed for motor field suppression has not expired yet (before subsequent start). |
| 5 | W12 - Process regulator is saturated. Converter frequency has reached its maximum value. |
| 6 | F9 - Position calibration initiated by 9.4.3 command, or calibration of IRC encoder on the synchronous motor. |
| 7 | F11 - The speed decreased to zero by activating a software terminal switch. |
| 8 | F8 - Dynamic deceleration was activated as a result of a sharp decrease in speed. |
| 9 | W16 - Sensored motor temperature has achieved nonpermissible value. |
| 10 | W17 - If EWCP,(M),(I) panel is active (2.4.1)and the connection with the converter has failed. |
| 11 | F2 - Maximal current regulator (par.13.3.1) is active. It limits the current to the value of parameter 9.10.1 |
| 12 | F3 - The converter is in kinetic backup mode after input power failure. |
| 13 | F4 - The converter is processing the frequency for the spinning motor. |
| 14 | F5 - Sleep function of process regulator. |
| 15 | F6 - Braking unit is active. |

Warnings register 2 (values of the I/O tag with address #0044). If an arbitrary bit is set to logical 1, the converter generates a corresponding warning.
| Bit | Meaning |
|---|---|
| 0 | W23 - The converter recognized no load at output terminals U, V, W at START command. |
| 1 | F12 - Terminal switch 1 or terminal switch 2 is switched on. |
| 2 | F13 - The function „flux braking“ (8.3.1) increases motor excitation proportionally to UDC-UDCnom |
| 3 | W9 - Converter input phase was interrupted |
| 4 | reserved |
| 5 | F14 - OFF-LINE identification of some motor parameters (Rs, Ls+Lm, Uinit). |
| 6 | W25 - The air temperature in the converter is more than 70 °C. |
| 7 | reserved |
| 8 | W18 - Serial communication error has occurred - RS232 (RS485) |
| 9 | F16 - It signalizes, that relay with the function „shut-down, overload“ has just been released. |
