6A.4.3 Digital Output Configuration (RO1- Fault)
When the control supply line is external, it is not possible to set the fixed output relay RO1 Fault if the main power is not present.
If a digital output is required to relay the Drive Fault condition, it is possible to use the other digital outputs (RO2, RO3, DO4, DO5, DO6) configured as
Drv Fault. The following example explains how to configure the digital output DO6.
Remark The drive fault condition is activated when the relative digital output is 0:
 DO6 = 1 (24 V)  NO Trip occurred
 DO6 = 0 (0 V)  Trip occurred
