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.
z The output voltage is automatically set by intelligent mode when "4" (energy-saving mode) is set in Pr. 60
"intelligent mode selection". (Refer to page 100.)

Setting Output Characteristics Application
0 For constant-torque load Conveyor, cart, etc.
1 For variable-torque load Fan, pump
2
For constant-
torque lift
Boost for reverse rotation 0% Boost for forward rotation...Pr. 0 setting
For lift load
3 Boost for forward rotation 0% Boost for reverse rotation...Pr. 0 setting
4 RT signal
ON...For constant-torque load (same as in setting = 0)
Load pattern selection
switching function using RT
signal
OFF...For constant-torque lift, boost for reverse rotation 0% (same as in
setting = 2)
5 RT signal
ON...For constant-torque load (same as in setting = 0)
OFF...For constant-torque lift, boost for forward rotation 0% (same as in
setting = 3)
Note: 1. This parameter setting is ignored when Pr. 80 and Pr. 81 have been set to select the advanced
magnetic flux vector control mode.
2. When the RT signal is on, the other second functions such as second acceleration/deceleration
time and second torque boost are also selected.
3. When the setting is 4 or 5, X17 signal may be used instead of the RT signal. Use any of Pr. 180
to Pr. 186 to assign the terminal used to input the X17 signal.
Pr. 0 "torque boost"
Pr. 60 "intelligent mode selection"
Pr. 80 "motor capacity"
Pr. 81 "number of motor poles"
