Chapter 17 Safe Torque Off FunctionMS300 (High Speed Model)
17-8
17-6-4 STL1, Pr. 06-44=0 or 1
As shown in Figure 8: When S1~DCM is OFF during operation (STO function is required) and
S2~DCM is ON (STO function is not required), the drive will stop outputting and keypad will
show STL1 error. However, STL1 error cannot be reset even if the S1 status is restored (ON)
regardless of the parameter setting. Turn the power on after power off to reset, thereby the
drive can restore to normal standby state.
