Setting Output Characteristics Application
0 For constant-torque load Conveyor, cart, etc.
1 For variable-torque load Fan, pump
2 Boost for reverse rotation 0% Boost for forward rotation...Pr. 0 setting
3
For constant-
torque lift
Boost for forward rotation 0% Boost for reverse rotation...Pr. 0 setting
For lift load
ON...For constant-torque load (same as in setting = 0)
4 RT signal
OFF...For constant-torque lift, boost for reverse rotation 0% (same as in
setting = 2)
ON...For constant-torque load (same as in setting = 0)
5 RT signal
OFF...For constant-torque lift, boost for forward rotation 0% (same as in
setting = 3)
Load pattern selection
switching function using
RT signal
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.
Jog operation (Pr. 15, Pr. 16)
Pr. 15 "jog frequency"
Pr. 16 "jog acceleration/deceleration time"
In the external operation mode, jog operation can be started and stopped with the start signal (STF, STR)
after selection of the jog mode (JOG signal ON). In the PU operation mode, jog operation can also be
performed using the PU (FR-DU04/FR-PU04).
Set the frequency and acceleration/deceleration time for jog operation

Note: 1. In S-shaped acceleration/deceleration pattern A, the set time is a period of time required to reach
Pr. 3 "base frequency".
2. The acceleration time and deceleration time cannot be set separately for jog operation.
