Hello,
I have a GPIO input which goes high when there is a fault. When this happens I want to force my PWM outputs off. So ideally I would like to connect the GPIO pin to a TZ input (1 to 3) via the Input X-BAR to ePWM.
At the top of page 1913 of the manual (SPRUHM8I) it says:
"The trip-zone signals TZ1 to TZ6 (also collectively referred to as TZn) are active low input signals."
So I concluded that my active high GPIO fault input cannot be used with active low TZ1-TZ3 inputs.
However, on page 1926 it appears to say that TZ active state is configurable:
I cannot see where to defined active high or active low state for TZ1-TZ3 when used as DC input.
Please can you confirm whether TZ1-TZ3 can be configured to be active high to suit my hardware application?
Thank you.
