Overspeed
Motor is turning faster than
highest allowed speed due to
incorrectly set
minimum/maximum speed,
insufficient braking torque or
changes in load when using
torque reference.
Check minimum/maximum speed
settings, parameters

.
Check adequacy of motor braking torque.
Check need for brake chopper and
resistor(s).
