3.4 INPUTS & OUTPUTS
Multi-function Input Signals (n036 to n040)
Multi-function contact input terminal S2 to S6 functions can be changed when
necessary by setting parameters n036 to n040, respectively. None of these
parameters can receive a setting common with the other (no duplication).
·Terminal S2 function: set via parameter n036
·Terminal S3 function: set via parameter n037
·Terminal S4 function: set via parameter n038
·Terminal S5 function: set via parameter n039
·Terminal S6 function: set via parameter n040
* 2 to 6 are displayed in _ corresponding to S2 to S6, respectively.
Factory settings: n036 = “Reverse RUN (2W)”, n037 = “Ext Fault (NO)”, n038 = “Fault
Reset”, n039 = “Multi-Step Spd 1”, n040 = “Multi-Step Spd 2”

Ext Fault (NO) External fault (normally open)
Inverter stops at fault when external fault signal is
input. Digital operator displays “EFX”.
