setting = 2)

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.
