STL2, Pr.06-44=0 or 1
As shown in the figure below, when S1–DCM is ON during operation (STO function is not required) and S2–DCM is
OFF (STO function is required), the drive stops outputting and the keypad shows the STL2 error. However, you
cannot reset the STL2 error even if the S2 status is restored (ON) regardless of the parameter setting. You must
cycle the power to reset and to restore the drive to the normal standby state.
