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

Load pattern
selection
1 0, 1, 2, 3
0: For constant-torque loads
1: For variable-torque loads
2: For vertical lift loads
3: For vertical lift loads
Setting is
enabled when
Pr. 30 = "1".
CAUTION
1. When automatic torque boost control is selected, this parameter setting is
ignored.
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.
