As shown in Fig. 17-8, when S1–DCM is OFF during operation (STO function is required) and
S2–DCM is ON (STO function is not required), the drive stops outputting and the keypad shows the
STL1 error. However, you cannot reset the STL1 error even if the S1 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.
