Quick stop [G] [WG]
With Quick stop defined in CiA 402, the servo motor can be stopped by the forced stop deceleration. For details of the forced
stop deceleration, refer to the following.
Page 128 Forced stop deceleration function
When the Quick stop command in [Controlword (Obj. 6040h)] is turned off, the servo motor decelerates to a stop in
accordance with the setting of [Quick stop option code (Obj. 605Ah)], following which the status changes to "Switch On
Disabled" (servo-off).
• This function can be used in the cyclic synchronous mode (csp/csv/cst), profile mode (pp/pv/tq), and
homing mode (hm).
• In the torque mode or continuous operation to torque control mode (ct), the servo motor stops with the
dynamic brake without deceleration to a stop.
Objects for setting
For details on the objects, refer to the User's Manual (Object Dictionary).
The methods and operations supported in [Quick stop option code (Obj. 605Ah)] are shown in the following table.

Description
1
(not supported)
csp/csv: The servo motor decelerates to a stop with [Quick stop deceleration (Obj. 6085h)], and the state shifts to "Switch On Disabled".
cst/tq: The state shifts immediately to "Switch On Disabled", and the servo motor stops with the dynamic brake.
pp/pv: The servo motor decelerates to a stop with Profile deceleration (6084h) and the state shifts to "Switch On Disabled".
hm: The servo motor decelerates to a stop in accordance with [Homing acceleration (Obj. 609Ah)] and the state shifts to "Switch On
Disabled".

In the cyclic synchronous mode (csp/csv), profile mode (pp/pv), and homing mode (hm), the servo motor decelerates to a stop with [Quick
stop deceleration (Obj. 6085h)] and the state shifts to "Switch On Disabled".
In the cyclic synchronous torque mode (cst), profile torque mode (tq), and continuous operation to torque control mode (ct), the state
immediately shifts to "Switch On Disabled" and the servo motor stops with the dynamic brake.
3
(not supported)
The servo motor decelerates by limiting the current, following which the state shifts to "Switch On Disabled".
4
(not supported)
The servo motor decelerates by limiting the voltage, following which the state shifts to "Switch On Disabled".
5
(not supported)
After deceleration to a stop, the state remains as "Quick Stop Active". (Servo-on is maintained.)
6
(not supported)
After deceleration to a stop with [Quick stop deceleration (Obj. 6085h)], the state remains as "Quick Stop Active". (Servo-on is maintained.)
7
(not supported)
After deceleration by limiting the current, the state remains as "Quick Stop Active". (Servo-on is maintained.)
8
(not supported)
After deceleration by limiting the voltage, the state remains as "Quick Stop Active". (Servo-on is maintained.)
