Fault (Temperature Warning) Output
The MDriveAC Plus Microstepping features an Open-Drain Fault output located at Pin 19 of connector P1. This
is an impending over-temperature and over-temperature fault.
When the internal temperature of the MDriveAC Plus reaches the temperature specified by the WARN_TEMP
parameter, the output will pulse at 1 second intervals (1/2 second on, 1/2 second off). When an over-temperature
fault state is reached the output will latch on.
The output will remain in the latched condition until a power cycle, or new parameter set from the IMS SPI Mo-
tor Interface.
