Half or full step mode is selected by the position of jumper JP1. See
Section
1.4: Theory of Operation
, for an explanation of the modes.
F a u l t P r o t e c t i o n C i r c u i t r y / F a u l t O u t p u t
The INT-462H adds phase to ground fault protection to the IB462H. If a
phase to ground fault is detected, the driver will set the fault output and the
red LED will illuminate.
In order to clear a fault condition, the power must be cycled or the RESET
input toggled.
F a u l t O u t p u t
The INT-462 buffers the fault output signal through an open drain N-channel
FET. The signal at the terminal strip is inverted, thus it is active when in a
logic LOW state. See
Table 2.1.2
of this section for the electrical characteris-
tics of this output.
