S Monitoring at Startup
• In
operation mode, the frequency reference, output
frequency
, output current, and output voltage can
be
monitored immediately if the default settings are being used. One of these four
values, the output
voltage,
can be changed to a dif
ferent value. When a value other than the output voltage is to be moni
-
tored, set that value’s number in parameter o1-01 (user monitor selection).
• When
the power is turned on, the frequency reference will appear in the Unit’
s data display if the de
-
fault settings are being used. Any one of the four values monitored at startup (frequency reference,
output
frequency
,
output current, or the value set in parameter o1-01) can be selected to appear when
the
power is turned on. The value that appears at startup is determined by parameter o1-02 (Power-
On Monitor).
• Parameters
o1-01 and
o1-02 can be changed in the Basic or Advanced access levels. These parame
-
ters can be changed during operation.
User Monitor Selection (Parameter o1-01)
Use parameter o1-01 to select the values that will be monitored at startup.
Use the last two digits from the “U1 Monitor” list (U1-) to select a value. For example, the torque
reference is U1-09, so input 9 to select the torque reference.

The
following example shows how to change parameter o1-01 so that the output power is monitored at
startup instead of the output voltage.
Key sequence Display Explanation
** Main Menu **
Operation
Displays operation mode.
** Main Menu **
Programming
Displays program mode.
Function b1
Sequence
Puts the Unit in program mode.
2 times
Function o1
Monitor Select
Displays function selection o1.
User Monitor Sel
Output Voltage
Puts the Unit in function selection o1. (Monitor Select)
o1-01= 6 ***
Output Voltage
Displays the parameter setting for o1-01.
2 times
o1-01= 8 ***
Output kWatts
Sets the parameter to output power.
Entry Accepted
Writes the new setting.
User Monitor Sel
Output kWatts
Returns to the Monitor Select display.
Note In this example, the setting is changed in the Basic access level.
Power-On Monitor (Parameter o1-02)
Use parameter o1-02 to indicate which value will be displayed when the Unit is started.
A
setting of 1 indicates the frequency reference, 2 indicates the output frequency
, 3 indicates the output
current, and 4 indicates the value set in parameter o1-01.
