The use of frequency converters for fans is also a very popular application. This includes smoke exhausters, supply or exhaust ventilation, aspiration, etc. In this article, we will look at the main parameters for this application. Since proper settings are the key to the normal functioning of the mechanism and will extend its service life, let's move on to the parameters of these frequency converters. Interestingly, the parameters for this application will be the same across all three series.
| Parameter | Description | Value |
| F00.03 | Reset to factory settings | Set value to 22. |
| F02.01 | Number of motor poles | Value from the motor nameplate, or 3000 rpm - 2, 1500 rpm - 4, 1000 rpm - 6, etc. 2*(3000/motor rpm) |
| F02.02 | Rated motor power, kW | Value from the motor nameplate |
| F02.03 | Rated motor frequency, Hz | Value from the motor nameplate |
| F02.04 | Rated motor voltage, V | Value from the motor nameplate |
| F02.05 | Rated motor speed, rpm | Value from the motor nameplate |
| F02.06 | Rated motor current, A | Value from the motor nameplate |
| F02.07 | Motor auto-tuning | 1. Dynamic tuning (with load connected) 2. Static tuning (if disconnecting the load is not possible). After selection, press the run button. r00-r01-r02-r03-frequency 50.00 or an error code will be displayed. |
| F01.00 | Control type | 0. Asynchronous motor, scalar control |
| F01.01 | Frequency inverter start method | 0. Start from panel (Run/Stop buttons) 1. Start from terminals |
| F01.02 | Frequency setting channel | 0. Frequency set from buttons on the control panel 1. Frequency set by potentiometer on the panel (if available depending on the model) 2. Frequency set from remote potentiometer for series AC310 and AC10 3. Frequency set from remote potentiometer for series AC01 |
| F01.13 | Minimum frequency | Set the minimum motor operating frequency (choose not less than 15Hz or when the effect starts to appear) |
| F01.21 | Acceleration time setting | Set the motor acceleration time in seconds (usually not less than 15-20 s) |
| F01.22 | Deceleration time setting | Set the motor deceleration time in seconds (usually not less than 20 s) |
| F07.06 | Auto-start after power loss/power restoration | 0. Disabled 1. Auto-catch with speed search (recommended) |
| F07.07 | Auto-start delay time after power restoration | Set the auto-start delay time after power appears. (recommended 1 second or more) |
| F07.10 | Stop mode | 0. Smooth stop (according to parameter F01.22) 1. Coast stop (recommended) parameter F01.22 disabled |
| F04.00 | U/F curve selection | 0 – linear dependency 1 – power 1.1 2 - power 1.2 3 - power 1.3 4 - power 1.4 5 - power 1.5 6 - power 1.6 7 - power 1.7 8 - power 1.8 9 - power 1.9 10 - power 2 (quadratic) 11 – custom by 5 points (parameters F04.10 – F04.19) Recommendation: either select according to the fan curve if known or adjust so that the current consumption is minimal. This will be the optimal curve. |
Here is the set of necessary parameters for starting the fan operation. If you have additional questions or if the mechanism does not operate as you need, you can refer to the frequency converter's user manual or contact our technical support department, which will assist you.
