15-6-5 STL2, Pr.06-44=0 or 1
As shown in Figure 9, 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.
