Monitoring at Startup

In operation mode, the frequency reference, output frequency, output current, and output voltage can be

monitored immediately if the factory presets are being used. One of these four values, the output voltage,

can be changed to a different monitor item. When an item other than the output voltage is to be monitored,

set that value in user constant o1-01 (Monitor selection). Refer to the example procedure given later in this

manual.
When the power is turned ON, the frequency reference will appear in the Unit’s data display if the factor

presets are being used. Any one of the four values monitored at startup (frequency reference, output frequen-

cy, output current, or the value set in user constant o1-01) can be selected to appear when the power is turned

ON.
The value that appears at startup is determined by user constant o1-02 (Monitor selection after power up).
User constants o1-01 and o1-02 can be changed in the Basic or Advanced access levels. These user constants

can be changed during operation.

Use the last two digits from the U1 Monitor list (U1-09) to select a value. For example, the torque reference

is U1-09, so input 9 to select the torque reference.

Setting Range

The setting range for the constant.

Units

The unit used to set the constant (“--” indicates that no unit is used).

Factory Setting

The value preset at the factory. (There are different factory settings for each control method,

i.e., if the control method is changed, the factory setting can also change.)
