<Setting>
Refer to the figure below and set the corresponding parameters:
• When Pr. 43 ≠ 9999, the Pr. 42 setting applies to forward rotation and the Pr. 43 setting applies to reverse
rotation.
Output Signal
Use Pr. 190 to Pr. 195 to assign the terminals used to output the FU2 and FU3 signals.
4.2.20 Second/third stall prevention (Pr. 48, Pr. 49, Pr. 114, Pr. 115)
Pr. 48 "second stall prevention operation current"
Pr. 49 "second stall prevention operation
frequency"
Pr. 114 "third stall prevention operation
current"
Pr. 115 "third stall prevention operation
frequency"
z The stall prevention operation level can be changed within the range from 0Hz to the frequency set in
Pr. 49 or Pr. 115.
z The stall prevention operation level can be changed by switching the external input signal on-off.

Note: 1. When the plug-in option unit is used to exercise encoder feedback control, use the RUN (running)
signal. (If the FU, FU2 or FU3 signal is used, the brake may not be opened.)
2. Changing the terminal assignment with any of Pr. 190 to Pr. 195 may affect the other functions.
Make setting after checking the functions of the corresponding terminals.
