 Torque setting current (voltage) bias/gain adjustment method
 Adjustment by applying current (voltage) between terminals 4 and 5 to set the current (voltage)
at the bias/gain torque
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 (Pr.933) 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.
Do not touch the setting dial and UP/DOWN key until calibration is completed.
7.
Applying current (voltage)
Apply a 20 mA (5 V). (Turn the external potentiometer connected between terminals 4 and 5 to a desired position.)
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.
