Periodic Test; Examples Of Wiring Diagrams Of Inverter Control Signal - WEG CFW-11 Guía De Instalación, Configuración Y Operación

Table 5: 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 CFW-11 inverter programming manual for a complete list of options for parameters

3.4 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 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.

4 EXAMPLES OF WIRING DIAGRAMS OF INVERTER CONTROL SIGNAL

It's recommended to use inverter DI1 and DI2 digital inputs set as 3-wire start/stop commands
and the wiring diagrams of inverter control signal according to figure 4.
