Adjustment by selecting the voltage at the bias/gain frequency without applying voltage between
terminals 1 and 5 (Example of adjustment at the gain frequency)
Operating procedure
1.
Turning ON the power of the inverter
The operation panel is in the monitor mode.
2.
Changing the operation mode
Press the PU/EXT key to choose the PU operation mode. The [PU] indicator turns ON.
3.
Selecting the parameter setting mode
Press the MODE key to choose the parameter setting mode. (The parameter number read previously appears.)
4.
Selecting a calibration parameter
Turn the setting dial or press the UP/DOWN key until "C..." appears. Press the SET key to display "C---".
5.
Selecting a parameter
Turn the setting dial or press the UP/DOWN key until "C15" (C15 (Pr.918) Terminal 1 gain (speed)) appears.
6.
Displaying the analog voltage value
Press the SET key to display the analog voltage value (%) currently applied to terminal 1.
7.
Adjusting the analog voltage value
After the setting dial is turned or the UP/DOWN key is pressed, the gain voltage value (%) currently set to the parameter
appears.
Turn the setting dial or press the UP/DOWN key until the gain voltage to be adjusted appears.
8.
Setting completed
Press the SET key to confirm the setting. The analog voltage value (%) blinks when it is applied.
• Turn the setting dial or press the UP/DOWN key to read another parameter.
• Press the SET key to return to the "C---" display.
• Press the SET key twice to show the next parameter.
NOTE
• The present frequency setting bias/gain setting can be checked by pressing the setting dial or pressing the UP/DOWN key
one time after step 6. The setting cannot be checked after step 7.
