MC_Stop

Name :Stop the instruction

Symbol :MC_Stop

Illustrate:

    It is used for the shaft to realize the emergency stop function, and the command rising edge is effective.
    This command can only be invoked if the axis is enabled using the MC_Power command.
    On the rising edge of the EXECUTE, the input DECE value is locked, and the PLCOpen state machine of the axis switches to Stopping and does a deceleration and shutdown motion.
    The DONE signal is valid after stopping, and when EXECUTE=TRUE, DONE is maintained, and the axis state is kept at Stopping.
    EXECUTE=OFF, and has stopped, the PLCOpen state machine of the axis is switched from Stopping to Standstill.
    If the same MC_Stop command is re-triggered during the execution of the order, the deceleration at the time of the last trigger is used.
    Instructions cannot be called multiple times, and other MC_Stop instructions are invoked during the validity period of one instruction, and other MC_Stop instructions will report errors.
    This command cannot be interrupted, and the motion command cannot be executed when the PLCOpen state machine of the axis is Stopping (refer to the PLCOpen state machine of the axis).

Parameter:

The name of the parameter	data type	IN/OUT	Parameter role	Illustrate	Default value
AXISNO	UDINT	IN	Pulse shaft number	0-7	not
EXECUTE	BOOL	IN	Function block triggering	The rising edge triggers the execution of the order	FALSE
DECE	REAL	IN	Deceleration	Deceleration(0 - Stop immediately; non-0 - Absolute value valid), ≤ maximum acceleration, in units：unit/s	not
DONE	BOOL	OUT	Shutdown Complete flag	TRUE：The shutdown is complete	FALSE
BUSY	BOOL	OUT	Busy sign	TRUE：Deceleration is being stopped	FALSE
ERROR	BOOL	OUT	Error flags	TRUE：There was an error with the function block call	FALSE
ERRORID	UINT	OUT	Error codes	0：Normal, Other: Error code value	0

Example:

LD:

ST:


MC_Stop_inst1(AXISNO := 0,
 EXECUTE     := TRUE,
 DECE        := 100,
 DONE       => DoneOut,
 BUSY       => BusyOut,
 ERROR      => ErrorOut,
 ERRORID    => ErrorIdOut);

Interpretation:

   AXISNO is 0, which means that the operating pulse axis is 0;
   EXECUTE is executed by FALSE->TRUE, and the rising edge triggers the function block to execute;
   DECE is 100, which means deceleration at 100 unit/s until it stops.
   If DoneOut is TRUE, the deceleration and shutdown are complete.
   BusyOut is TRUE, which means that the deceleration is stopping, and BusyOut is reset after completion.
   If ErrorOut is TURE, it means that there is an error and the command cannot be executed.
   If ErrorIdOut is 0, the execution is normal, and if it is not 0, there is an error and cannot be executed.
