9.2.12 Selection of an actual value for display
After commissioning, the value of parameter
Actual Frequency
241 is displayed at the control unit
KP500.
If another actual value is to be displayed after a restart, make the following settings:
 Use the arrow keys to select the actual value to be displayed as from now.
 Use the ENT key to display the value of the parameter.
 Press the ENT key again. "SEt" is displayed for confirmation.
As from now, the selected actual value is displayed after each restart.
If the parameter settings were made via the optional control software or in the PARA menu branch
of the operating unit, the display of the selected actual value must be activated manually. Use the
ESC key to switch to the selection of the actual value for display again.
9.3 Check direction of rotation
WARNING
Before any assembly or connection work, discharge the frequency inverter. Verify
safe isolation from power supply.
When the frequency inverter is disconnected from power supply, the mains, DC-link
voltage and motor terminals may still be live for some time. Work on the device may
only be started once the DC link capacitors have discharged. The time to wait is at
least 3 minutes in the case of sizes 1 through 7 .
To check if the reference value and the actual direction of rotation of the drive correspond to one
another, proceed as follows:
 Operate the drive at low speed, i. e. specify a reference value of approx. 10%.

Switch on release of frequency inverter briefly:
Connect digital inputs S1IND/STOA and S7IND/STOB as well as S2IND (Start Clockwise) or
digital inputs S1IND/STOA and S7IND/STOB as well as S3IND (Start Anticlockwise) .
 Check if the motor shaft turns in the required direction.
In case the sense of rotation is wrong, exchange two motor phases, e.g. U and V at the
terminals of the frequency inverter. The mains-side connection of the frequency inverter does
not affect the sense of rotation of the drive. In addition to checking the drive, the corresponding
actual values and operating messages can be read out by means of the operating unit.
The commissioning of the frequency inverter is complete and can be complemented
by further settings in the PARA menu. The set parameters have been selected in such
a way that they are sufficient for commissioning in most applications. The other
settings which are relevant to the application can be checked according to the
operating instructions.
