20.8.11 Halt
When Halt Bit (Bit 8 of Controlword (CiA 402 standard)) is set to 1, the servo motor decelerates to a stop with
the deceleration time constant of Homing acceleration (P24730), Profile deceleration (P24708) or the point
table according to the setting of Halt option code (P24669). This function can be used in Profile mode,
homing mode (hm) and point table method (pt/jg).
When Halt Bit is set to 0 at deceleration stop operation, the servo motor decelerates to a stop and returns to
the operable state. The following table lists the related objects.

Refer to table 8.11 for details.
The following table shows descriptions of Halt option code. However, in the tq mode, Torque demand value
(P24692) is set to 0 regardless of Halt option code. The amount of torque change at this time can be set
using Torque slope (P24711).

Description
1
The motor decelerates to a stop in accordance with the deceleration time constant of Profile deceleration (P24708) in
pp/pv/jg, of Homing acceleration (P24730) in hm, and of the point table in pt, and the state does not change from Operation
Enabled (servo-on).
2
The servo motor decelerates to a stop with Quick stop deceleration (P24709). The state does not change from Operation
Enabled (servo-on). (Not compatible) (Note)
3
The current is limited and the servo motor decelerates to a stop. The state does not change from the Operation Enabled
(servo-on). (Not compatible) (Note)
4
The voltage is limited and the servo motor decelerates to a stop. The state does not change from the Operation Enabled
(servo-on). (Not compatible) (Note)
Note.
This is not supported by the driver.
20.8.12 Ramp Stop
This decelerates the motor to a stop with the off command of Control word 1 (PROFIdrive standard) in the
Operation state. The deceleration to a stop is according to a deceleration time constant of Profile deceleration
(P24708).
