Corrective Actions
1) Check the wiring of the Y-connection/Δ-
connection.
2) Check the parameters settings.
1) Set P6.61 to 0.
2) Check if input power is stable.
1) Check if motor parameter is correct (please
decrease the load if overload).
2) Check the settings of P2.26 and P2.27.
Do not disconnect RST when drive is still
operating�
n/a
STO1~SCM1 internal hardware detect error�
(See Appendix E for corrective action�)
Fault S1 is generated upon a loss of the E-Stop
input at ES1�
The corrective action is to restore the E-Stop
input to the drive at ES1�
Fire fault is due to the multi-function input set
as 40 or 41 and that DI is ON�
For some installations, particularly exhaust fan
operation where smoke is detected and requires
evacuation, it is highly desired for the drive to
run the fan as long as is needed to exhaust that
smoke�

If unknown STO faults occur, the onboard +24V
might be getting shorted (+24V to DCM)�
