Configurable I/O Application Functions

Logic output application functions

Relay R2, LO solid state output (with I/O extension card)

Downstream contactor control (OCC): can be assigned to R2 or LO

Enables the speed controller to control an output contactor (located between the speed controller and the motor). The request to close the contactor is made when a run command appears. The request to open the contactor is made when there is no more current in the motor.

If a DC injection braking function is configured, it should not be left operating too long in stop mode, as the contactor only opens at the end of braking.

Speed controller running (RUN) : can be assigned to R2 or LO

The logic output is at state 1 if the motor power supply is provided by the speed controller (current present), or if a run command is present with a zero reference.

Frequency threshold reached (FTA) : can be assigned to R2 or LO

The logic output is at state 1 if the motor frequency is greater than or equal to the frequency threshold set by Ftd in the adjust menu.

Setpoint reached (SRA): can be assigned to R2 or LO

The logic output is at state 1 if the motor frequency is equal to the setpoint value.

High speed reached (FLA): can be assigned to R2 or LO

The logic output is at state 1 if the motor frequency is equal to HSP.

Current threshold reached (CTA): can be assigned to R2 or LO

The logic output is at state 1 if the motor current is greater than or equal to the current threshold set by Ctd in the adjust menu.

Motor thermal state reached (TSA) : can be assigned to R2 or LO

The logic output is at state 1 if the motor thermal state is greater than or equal to the thermal state threshold set by ttd in the adjust menu.

Drive thermal state reached (TAD) : can be assigned to R2 or LO

The logic output is at state 1 if the drive thermal state is greater than or equal to the thermal state threshold set by dtd in the adjust menu.

Brake sequence (BLC) : can only be assigned to relay R2

Used to control an electromagnetic brake by the speed controller, for vertical lifting applications. For brakes used for horizontal movement, use the “speed controller running“ function.
