Installation and Connection
Table 3.12 - P0275...P0279 options for indication of state of inverter or faults on DOx digital outputs
DOx Digital Output Function
State of the inverter = STO
(Safety Stop function activated)
F160 fault
(inverter tripped by Safety Stop function fault actuation)
Fault
(inverter tripped by actuation of any fault)
Without fault
(state of the inverter is not fault)
Refer to inverter programming manual for a complete list of options for parameters P0275...P0279.

3.3.2.4 Periodic Test

Safety Stop function, alternatively safety stop inputs (STO1 and STO2), must be activated at least once a year
for preventive maintenance purposes. Inverter power supply must be switched off and then on again before
3
carrying out this preventive maintenance. If during testing the power supply to the motor is not switched off,
safety integrity is no longer assured for the Safety Stop function. The drive must therefore be replaced to ensure
the operational safety of the machine or of the system process.
