Adjustment by selecting the voltage at the bias/gain torque without applying voltage between
terminals 1 and 5
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 "C19" (C19 (Pr.920) Terminal 1 gain (torque)) 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 torque 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.
