Before performing operation with the mechanical system actually connected, operate the motor with
no load (i.e., not connected to the mechanical system) using the Digital Operator keys.
• Check that no faults have occur in the Inverter during operation.
• Check that the directions of rotations match. If operation is in the wrong direction, reverse any two
of the motor output wires.
• The Increment and Decrement Keys can be used to change the frequency when the
@
Hz set indi-
cator is lit.
• Refer to
3-4-3 Changing the Frequency Reference
