Output Descripti ons

Brake: The Brake output is activated on any fault condition. This provides a control signal to
engage a brake when the Impulse loses torque due to a fault. The Brake output also provides a
polarity-conf igurable fault outpu t since the ded icated fault output is fixed as an active high, si nking
output. Note: The Brake output is not intended nor designed as a power source for a mechanical
brake.
In Motion: The In Motion output is activated upon receiving incoming step pulses or when a stored
move (Motion Node option) is running. The minimum step frequency that the internal velocity
tachometer can render is 156.25 Hz (156.25 / Step Resolution in RPS). Input step frequencies below
156.25 Hz will not activate the In Motion output.
Stall: The Stall output is activated when OLSD™ (Open Loop Stall Detect) detects a motor stall.
