14.2.6 Example 6: Enable inverter
This example shows how to use the "Enable inverter" funcon for a separate enable input.
•
In idle state of switch S1 (normally-closed contact), "Enable inverter" is already available.
•
Switch S2 starts the motor in forward rotang direcon (if switch S1 is closed). Switch S2 in
inial posion stops the motor again.
•
Switch S1 disables the inverter. The motor becomes torqueless (coasts).

①
If the inverter is enabled and no error is acve, the motor can be started with the "Run" funcon in forward rotang direcon.
②
If "Enable inverter" is set to FALSE, the inverter is disabled. The motor becomes torqueless and coasts to standsll as a funcon of the mass
inera of the machine.
③
Without "Enable inverter", the motor cannot be started.
④
In the default seng, the motor does not start if the "Run" funcon is set to TRUE during "Enable inverter" . Aer "Enable inverter", must
be retriggered to start the motor.
