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.
