FLT - Fault inputs

The FLT block configures and reads the digital fault inputs.

The fault input pin signals are tied to the fault manager and, using the FLT block, they can be configured to generate a “hardware fault” and immediately disable all the PWM outputs (similar to an analog input limit fault or any other fault). They can also be accessed as digital inputs like a GPI.

Simulink block

Signal specification

The output signal returns the value of one FLT pin.

Parameters

• Device ID selects which B-Box/B-Board to address when used in a multi-device configuration.
• Fault input(s) (vectorizable) selects the pin(s) to read.
• Activate fault input enable the generation of a “hardware fault” if the pin goes high and immediately disable all the PWM outputs.

PLECS block

Signal specification

The output signal returns a vector containing the values of the FLT pins. The vector size is defined by the number of FLT pin(s) read which is specified by the parameter Fault input(s).

Parameters

• Device ID selects which B-Box/B-Board to address when used in a multi-device configuration.
• Fault input(s) (vectorizable) selects the pin(s) to read.
• Activate fault input enable the generation of a “hardware fault” if the pin goes high and immediately disable all the PWM outputs.
