The two fault signals provide diagnostic feedback to the user’s control
system. These use the common ground to provide HI or LOW signals.
When both Fault Signals indicate HI, the EagleDrive is operating normally
(no faults detected). Signals are driven with 5.6kohm pull-up resistors to the
internal 5V and should be monitored with a high impedance device (R
load
>
100kohms).
Caution:
Do not short Fault Signals to ground or EagleDrive will not
operate properly.
