4-2 Function Mode Initial Screen Selection (Initial Screen at Power-ON) You can select the Digital Operator screen to be displayed at power-on among the following items. (By factory default, "01" (d001) is selected.) 4 Note: With "00" (screen on which the Enter key was last pressed) selected, if the last screen is other than d*** or F***, the entrance (*---) of each group is displayed. (Example) When the power is turned off and then on after a change in the A020 setting, "A---" is displayed.
Functions User Parameter Automatic Setting Function •When user parameter automatic setting function b039 is set to "01" (enabled), the parameters subjected to a data change are automatically stored in sequence (from U001 to U012). This data can be used as changed data. •The screen information is stored when the Enter key is pressed. The monitor screens (d***) are also stored in the same manner. •U001 is the most recent parameter, and U012 is the oldest. •The same parameter cannot be stored. If the number of parameters stored exceeds 12, the oldest data (U012) is erased.
Torque Limit Function •This function limits motor output torque when "03" (sensorless vector control), "04" (0-Hz sensorless vector control), or "05" (sensor vector control) is selected in control method A044/A244. 4-56 Parameter No. Function name Data Default setting Unit b038 Initial screen selection 00: Screen when the Enter key was pressed last 01: d001 (Output frequency monitor) 02: d002 (Output current monitor) 03: d003 (Rotation direction monitor) 04: d007 (Output frequency monitor [after conversion]) 05: F001 (Output frequency setting/monitor) 01 Parameter No. Function name Data Default setting Unit b039 User parameter automatic setting function selection 00: Disabled 01:
