7.3 Check direction of rotation
Warning! Dangerous voltage may be present at the motor terminals and the ter-
minals of the brake resistor even after the frequency inverter has been
disconnected from power supply. Wait for some minutes until the DC
link capacitors have discharged before starting to work at the unit.
• The unit may only be connected with the power supply switched off.
• Make sure that the frequency inverter is discharged.
To check if the reference value and the actual direction of rotation of the drive corre-
spond to one another, proceed as follows:
• Operate the drive at low speed, i.e. specify a reference value of approx. 10%.
• Release the frequency inverter briefly {signal at digital inputs S1IND (controller
release) and S2IND (start of clockwise operation) or S1IND (controller release)
and S3IND (start of anti-clockwise operation)}.
• 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 fre-
quency 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 control unit.
Note: The commissioning of the frequency inverter is complete and can be
complemented by further settings in the PARA menu. The set parame-
ters have been selected in such a way that they are sufficient for com-
missioning in most applications. The other settings which are relevant to
the application can be checked according to the operating instructions.
If the controller release of the frequency inverter at S1IND is switched off the power
output stage will be disabled. The motor will coast down or, if installed, a break will
be activated.
