Set the stall prevention operation level in Pr. 48 and Pr. 114.
Refer to the following list to set values in Pr. 49 and Pr. 115.
Pr. 114 and Pr. 115 are made valid by switching on the X9 signal. Set "9" in any of Pr. 180 to Pr. 186 to
allocate the terminal used to input the X9 signal.
Pr. 49 Setting
Pr. 115 Setting
0.01Hz to 400Hz
Cannot be set.
Note: 1. When Pr. 49 = "9999", setting "0" in Pr. 48 disables the stall prevention function when the RT
signal switches on. When Pr. 49 ≠ "9999" and Pr. 48 = "0", the stall prevention operation level is
0% when the frequency is equal to or less than the value set in Pr. 49.
2. When the stall prevention operation level signal input function is selected (Pr. 22 = 9999), setting
"9999" in Pr. 49 changes the stall prevention operation level from the value of the stall prevention
operation level signal (terminal 1 input) to the value set in Pr. 48 when the RT signal switches on.
3. When both the RT and X9 signals are on, the third stall prevention function is selected.
4. When the RT (X9) signal is on, the second (third) functions such as second (third)
acceleration/deceleration time are also selected.
5. When terminal assignment is changed using Pr. 180 to Pr. 186, the other functions may be
affected. Check the functions of the corresponding terminals before making setting.
Do not set a too small value to the second (third) stall prevention operation current.
Otherwise, torque generated will decrease.
Pr. 50 Î Refer to Pr. 42.

Second (third) stall prevention function is not activated.
Second (third) stall prevention function is activated according to the
frequency as shown above.
Second stall prevention function is activated according to the RT signal.
RT signal ON ..........Stall level Pr. 48
RT signal OFF ........Stall level Pr. 22
