All page numbers refer to the ER24 Programming Guide.

1. switch on the power supply to the drive without giving a run command (start command +24V and DI1) Observe the wiring diagram!

2. define the following settings:

- Set the rated motor frequency [Standard Motor Freq.] (bFr), page 84, if the frequency is not 50 Hz.

- Set the motor parameters in the [DRIVE DATA] (drC-) menu, page 103, only if the factory configuration of the drive is unsuitable.

- Set the application functions in the [INPUTS / OUTPUTS CFG] (I_O-) menu, page 124, in the CONTROL menu] (CtL-), page 153, and the [APPLICATION FUNCTION] (FUn-) menu, page 167, only if the inverter's factory configuration is not suitable.

Set the following parameters in the [SETTINGS (SEt-) menu:

- Start-up time] (ACC), page 85, and [Deceleration time] (dEC), page 85.

- Low frequency] (LSP), page 85, and

- [High frequency] (HSP), page 87.

- [Therm. current rating] (ItH), page 85.

After all preparations are complete, the run command / start command can be wired. (FI starts and drives off!)

1. To achieve electromagnetic compatibility, the inverter must be operated with a built-in or external radio interference filter.

2. If shielded cables are used between the inverter and the motor, the shield must be connected to earth at both ends. Cable interruptions should be avoided if possible. If it is necessary to separate the cable, e.g. to install a motor contactor, the cable shielding must be connected through as directly as possible. It is important to ensure that the lowest possible HF impedance is achieved.

3. The shorter the cable, the lower the radio interference and leakage current. The maximum possible cable lengths must be taken into account.

4. To avoid interference with the control inputs, control cables should always be shielded. The shield must be connected to the cable clamp provided on the inverter. If the shield is also connected to a control device, care must be taken to ensure that the ground points have the same potential.

5. Control cables should not cross power cables if possible. Where this cannot be avoided, a right-angled crossing is recommended.

6. Separate laying of control and power cables should be aimed for. If the cables must be laid parallel, e.g. on the same cable route, the largest possible distance (> 20 cm) should be selected.

7. The shielding of the laid cables should have a low HF impedance if possible. Copper braiding is therefore preferable to steel braiding.

8. The RF contact resistance at the connection points between shielding and housing must be kept as low as possible. Dirt, paint and insulation residues on the housing and shielding in the area of the connections must therefore be removed. In principle, the cable clamps or crimp connections provided for this purpose should be used to connect the shielding. It is advantageous to use earthing cable glands.

9. The shielding should be connected to the housing as close as possible to the cable terminals. Longer, free cable ends act as antennas.

10. With unscreened cables, the cable wires should be twisted and output filters should be used.

1. graphic display via a Modbus cable with the Modbus interface
(RJ45 connector) on the ER24 frequency inverter.

2. connect the mains voltage

3. press "ESC" repeatedly until the main menu appears

4. Select item "4 Open / Save as" and press "OK

5. Select item "4.1 Copy to inverter" and press "OK

6. select the desired data record (e.g. "File 1") and click "OK
press.

7. The submenu "Download group" appears. Now "All"
and press "OK".

8. The display shows: "Check the connection to the
Inverter" "ESC = Cancel OK=Apply", Now press "OK".

9. After error-free saving, the display shows: "Transfer
Complete" "OK OR ESC TO CONTINUE"
Now press "ESC" or "OK".

10.by pressing "ESC" several times to the starting point (e.g.
"Main menu").

Assuming that the ER24 is in the factory setting, the following are possible in the stopped
state (display: rdY) the following settings:

1. press ENT and select the COnF mode, then press ENT again

2. first select the item "FULL", scroll down to the parameter LAC and this
to AdV or EPr, press >2s ENT to save, then press ESC,
until LAC appears on the display again.

Scroll to the CtL- control menu, press ENT, find parameter FR2 and press
Set UPdt

4. set the parameter rFC to FR2 in the Control CtL- menu

5. call up the menu Application functions FUn- and select the parameter UPd- there

6. now call up the parameter "USP" and enter a "+ speed" for the assignment "+ speed".
Select free input e.g. LI5

7. finally, call up the "dSP" parameter and select a free
Select input e.g. LI6
Via input DI5 the speed is increased and via input DI6 the speed is
reduced.

1. Call up parameter FrY[PARAMETER GROUP] and select ALL, save with ENT and
then press ESC to exit the parameter.

2. Call parameter GFS [GOTO WORK SETTING] and select YES, then press the ENT key at least
Press and hold for 2 seconds to save.
