 Adjustment by selecting the current (voltage) at the bias/gain torque without applying current
(voltage) between terminals 4 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 LED 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.
Calibration parameter selection
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 "C41" (C41 Terminal 4 gain (torque/magnetic flux)) appears.
6.
Displaying analog current (voltage) value
Press the SET key to display the analog current (voltage) value (%) currently applied to terminal 4.
7.
Analog current (voltage) adjustment
After the setting dial is turned or the UP/DOWN key is pressed, the gain current (voltage) value (%) currently set to
the parameter appears.
Turn the setting dial or press the UP/DOWN key until the gain current (voltage) to be adjusted appears.
8.
Setting completed
Press the SET key to confirm the setting. The analog current (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.
