îš„ 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 page 4-11, Adjustment Suggestions if hunting, vibration, or other problems originated by the con-
trol system occur.
îš‹ Check and Recording User Parameters
Use verify mode to check user parameters that have been changed for trial operation and record them in a user
parameter table.
Any user parameters that have been changed by autotuning will also be displayed in verify mode.
If required, the copy function (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 set-
tings are saved in the Digital Operator, they can be easily copied back to the Inverter to speed up system
recovery if the inverter has to be replaced for any reason.
The following functions can also be used to manage user parameters.
• Recording user parameters
• Setting access levels for user parameters
• Setting a password
îš„ Recording User Parameters (o2-03)
If o2-03 is set to 1 after completing trial operation, the settings of user parameters will be saved in a separate
memory area in the inverter. When the Inverter settings have been changed for any reason, the user parameters
can be initialized to the settings saved in the separate memory area by setting A1-03 (Initialize) to 1110.
îš„User Parameter Access Levels (A1-01)
A1-01 can be set to 0 (monitoring-only) to prevent user parameters from being changed. A1-01 can also be set
to 1 (User-specified Parameters) to display only parameters required by the machine or application in a pro-
gramming mode. These parameters can be determined by setting the A2- parameters.
îš„Password (A1-04 and A1-05)
When the access level is set to monitoring-only (A1-01 = 0), a password can be set so that user parameters will
be displayed only when the correct password has been input.
