S Press the Mode Key until the V/F indicator is lit.
S The following two methods are available to set the V/f pattern.
S Select
one of the fixed 15 V/f patterns preset with the Inverter , in which case set the V/f pattern
to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, b, C, d, or E.
S Set the V/f pattern to F for an optional V/f pattern.
S The
following are the fixed V/f patterns preset with the Inverter . Refer to 3-4 Basic Operation for

S Select a V/f pattern suited to the mechanical system from the above V/f patterns.
S Set
the V/f pattern to F for an optional V/f pattern to be determined with n012 to n018. The optional
V/f pattern set with the Inverter before shipping is the same as the V/f pattern obtained with the set
value 1.
10. Operation with Actual Load
S Be ready to press the STOP/RESET Key for any error operation of the Inverter or the load.
S Use
the Digital Operator to operate the Inverter in the same way as the operation of the Inverter
with no load.
S Set
the frequency reference so that the motor will rotate at an approximately 10% of the rotation
speed of the motor in actual operation.
S Set
the frequency reference according to the actual rotation speed of the motor after making sure
that the mechanical system operates correctly and smoothly.
S Change the frequency reference and the rotation direction of the motor and check that the me-
chanical system operates without error vibration or noise.
