Stopping method
Description
Details
Servo braking
Servo driver delivers braking torque in
opposite direction
Quick stopping but mechanical
impact might exist
Free stopping
Motor power cut off. Free to move until
velocity = 0. Affected inertia, friction
and other factors
Smooth deceleration, low mechanical
impact but slow stopping
Dynamic braking
Brake activated when in motion
Quick stopping but mechanical
impact might exist
Stopping status
Status after stopped
Free moving
Motor is powered off, rotor is free to rotate
Dynamic braking
Motor is powered off, rotor is not free to rotate
Holding brake stopping
