17-6-4 STL1, Pr.06-44 = 0 or 1
As shown in Figure 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.

As shown in Figure 17-9, when S1–DCM is ON during operation (STO function is not required) and

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.
