DANGER 
Risk of unexpected motion with non-latched faults. 
After the cause of a non-latched fault is corrected, the amplifier re-enables 
the PWM output stage without operator intervention. In this case, motion 
may re-start unexpectedly. Configure faults as latched unless a specific 
situation calls for non-latched behavior. When using non-latched faults, be 
sure to safeguard against unexpected motion. 
Failure to heed this warning can cause equipment damage, injury, or 
death.
