4.2.9 Load pattern selection (Pr. 14)
Pr. 14 "load pattern selection"
You can select the optimum output characteristic (V/F characteristic) for the application
and load characteristics.

Note: 1. This parameter setting is ignored when the general-purpose magnetic flux
vector control mode has been selected.
2. Pr. 46 "second torque boost" is made valid when the RT signal turns on.
The RT signal acts as the second function selection signal and makes the
other second functions valid.
Refer to page 148 for Pr. 180 to Pr. 183 (input terminal function selection).
