Product line:

Environment:

Cause:
Parameter F856

Resolution:
The default setting for parameter F856 is 2 (4 pole motor).  You may need to change the number of motor poles to see the correct RPM value returned on the display.

F856 can be set to:
1 - 2 poles
2 - 4 poles (default)
3 - 6 poles
4 - 8 poles
5 - 10 poles

Note that the displayed value is based on nominal RPM and output frequency.  It does not take motor slippage into account.  The VFD does not monitor the actual motor RPM.
