6.1.6 Drive Stop
The servo stop modes include the coast to stop mode and zero-speed stop modeThe stop
states include the de-energized state and position lock state. Specic information is as
follows:
Table 6-5 Comparison of two stop modes
Stop Mode Stop Description Stop Characteristics
Coast to stop
The servo motor is de-
energized and decelerates
to stop gradually. The
deceleration time is affected
by the friction inertia and
mechanical friction.
This mode features smooth
deceleration and a small
mechanical impact, but the
deceleration process takes much
time.
Stop at zero speed
From the current speed
immediately stop at 0 speed
as the target speed
This mode features quick
deceleration but a larger impact.
Stop according to ramp
The speed reference stops
smoothly to stop at 0 speed
Smooth deceleration and small
mechanical impact, but the
deceleration process is controllable.
Emergency torque stop
The servo drive outputs the
reverse braking torque to stop
This mode features quick
deceleration but a larger impact.
DB brake The servo motor is working
This mode features quick
deceleration but a larger impact.
Table 6-6 Comparison of two stop states
De-energized State Position Lock
The motor is not energized after stopping
rotation, and the motor shaft can be rotated
freely.
The motor shaft is locked and cannot rotate
freely after the motor stops rotation.
The servo drive stops due to the following causes:

When the S-ON signal is turned off, it sets the deceleration mode of the servo motor from rotation to stop
and the servo motor status after stop.
Value Stop Mode
0 Coast to stop, keeping the de-energized state
1 Stop according to ramp, keeping the de-energized state
Set a proper stop mode according to the mechanical status and running requirement.
After the brake output is enabled, the stop mode at S-ON OFF is changed forcibly to "Stop at zero speed,
keeping de-energized state."
