nOperation Using the Digital Operator
• Use the Digital Operator to start operation in LOCAL mode in the same way as in no-load operation.
• Make sure the STOP Key on the Digital Operator is easily accessible so that any unexpected movement
can be stopped.
• At first, set the frequency reference to a low speed of one tenth the normal operating speed.
n Checking Operating Status
• Having checked that the operating direction is correct and that the machine is operating smoothly at slow
speed, increase the frequency reference.
• After changing the frequency reference or the rotation direction, check that there is no oscillation or abnor-
mal sound from the motor. Check the monitor display to ensure that U1-03 (Output Current) is not too
high.
• Refer to Adjustment Suggestions on page 4-18 if hunting, vibration, or other problems originating in the
control system occur.

K Check and Recording Parameters
Use verify mode (i.e., when the VERIFY indicator on the Digital Operator is lit) to check parameters that have
been changed for trial operation and record them in a parameter table.
Any parameters that have been change by autotuning will also be displayed in verify mode.
If required, the copy function in parameters o3-01 and o3-02 displayed in advanced programming mode can
be used to copy the changed settings from the Inverter to a recording area in the Digital Operator. If changed
settings are saved in the Digital Operator, they can be easily copied back to the Inverter to speed up system
recovery if for any reason the Inverter has to be replaced.
The following functions can also be used to manage parameters.
• Recording parameters
• Setting access levels for parameters
• Setting a password
n Recording Parameters (o2-03)
If o2-03 is set to 1 after completing trial operation, the settings of parameters will be saved in a separate mem-
ory area in the Inverter. Later, after Inverter settings have been changed, the parameters can be initialized to
the settings saved in the separate memory area when o2-03 was set to 1 by setting A1-03 (Initialize) to 1110.
nParameter Access Levels (A1-01)
A1-01 can be set to 0 (monitoring-only) to prevent parameters from being changed. A1-01 can also be set to 1
(User-specified Parameters) and used along with A2 parameters to display only parameters required by the
machine or application in a programming mode.
nPassword (A1-04 and A1-05)
When the access level is set to monitoring-only (A1-01 = 0), a password can be set so that parameters will be
displayed only when the correct password is input.
