Over-Voltage Protection
If the voltage supplied to the amplifier rises above its rated supply voltage, an Over-Voltage error will be reported.
While the amplifier is experiencing this condition, current is no longer commanded and the motor phases are
shorted together. This results in a drag on the motors causing them to coast to a stop. The amplifier will resume
commanding current when the voltage drops below the maximum rated supply voltage. The Over-Voltage
amplifier error is not a latching error.
If this error occurs, it is indicative of a problem at the system level. An Over-Voltage error is usually

due to regeneration from the motor and load. Consider using a shunt regulator if this occurs during
normal operation.
Abort/ELO Input
If the ELO jumper is installed, the power stage of the amplifier will be disabled when the Abort input is asserted.
The Abort input is a latching input with the ELO jumper installed, see the Clearing Latched Amplifier Errors section
for details.
Clearing Latched Amplifier Errors
Amplifier errors that do not latch will be reported in real-time by the
