MC_GroupDisable 2:

MC_GroupDisable 3:
(MC_GroupDisable 4: up to and including v3.2)

MC_GroupDisable 5:

The function block MC_GroupDisable disables the group. After successful execution the group changes into group state GroupDisabled (see State diagrams).

Notice

Disabling a Moving Group results in an instant stop.

The sudden stopping of axes is likely to exceed its allowed deceleration limits. Depending on the drive hardware, this could lead to current peaks and runtime errors.
Before executing MC_GroupDisable, use MC_GroupHalt or MC_GroupStop to avoid this situation.

Name

Type

Description

Done

BOOL

This output becomes TRUE when the command was successfully executed.

Busy

BOOL

This output becomes TRUE when the command is started with Execute and remains so as long as the function block executes the command. If Busy becomes FALSE again, the function block is ready for a new command. At the same time one of the outputs Done, CommandAborted (if available) or Error is set.

Error

BOOL

This output becomes TRUE if an error has occurred during command execution.

ErrorId

UDINT

Contains the command-specific error code of the last executed command. Details of the error code can be found in the ADS error documentation or in the NC error documentation (error codes 0x4nnn and 0x8nnn).
