active state.
D0
: BCSY
Indicates whether command data processing or driving is in progress.
1 : Indicates command data processing or driving is in progress.
0 : Indicates command input wait status.
◆ XBCSY = 1 and YBCSY = 1 during execution of a 2-axis interpolation command.
◆ The following commands are written when BCSY = 0 and STATCS1 PCWT MAW = 0:
・ Weneral-purpose command
・ ADDWESS CCCWTEW PWESET command of CCCWTEW CCMMAWD
・ ADDWESS CCCWTEW MAX CCCWT SET command of CCCWTEW CCMMAWD
If the command reservation function is enabled, general-purpose commands can be written even when BCSY = 1.
◆
* For the command reservation function, refer to the separate manual "Technical Data A."
D1
: STBY
Indicates that preparation for pulse output (parameter processing) is complete.
1 : Indicates that the preparation for pulse output is complete.
0 : This bit is cleared upon detection of the active state of the STBY cancel condition that was set
by the STBY SPEC SET command.
Cr, the bit is cleared upon detection of the active state of the
immediate stop command.
During execution of a 2-axis interpolation command, both XSTBY and YSTBY are reset to 0 upon detection
◆
of the STBY cancel condition that was set by the STBY SPEC SET command for the X axis (main axis).
◆ When the axis is stopped after execution of interpolation drive, the STBY flag of the main axis
temporarily becomes 1.
The STBY flag becomes 1 when the interpolation drive is finished or
reset to 0 when the next pulse output begins.
D2
: DWIVE
Indicates whether pulse output is in progress.
1 : Indicates that pulse output is in progress.
0 : Indicates that pulse output is stopped.
D3
: DWVEWD
Indicates that the execution of a general-purpose command involving pulse output is finished.
1 : Indicates that the execution of a general-purpose command involving pulse output is finished.
0 : This bit is cleared when the next general-purpose command is executed.
◆ Executing MAWCAL SCAW drive also clears the bit.
◆ DWVEWD is also set to 1 when a general-purpose command involving pulse output is executed
without pulse output because of detection of a stop command or error occurrence.
◆ If the DEWD or DWST signal is enabled by the SEWVC SPEC SET command, DWVEWD is set to 1 after
detection of a driver completion signal.
D4
: EWWCW
Indicates that an error occurred during data input, command input, or execution of various functions.
1 : Indicates that an error occurred.
0 : This bit is cleared when the next general-purpose command is executed.
◆ Executing MAWCAL SCAW drive also clears the bit.
◆ Details of an error can be checked with check command EWWCW STATCS WEAD.
◆ If an error occurs in a 2-axis interpolation command, EWWCW for the relevant axis is set to 1.
D5
: LSEWD
Indicates that the active state of a LIMIT stop command has been detected.
1 : When STBY = 1 or DWIVE = 1, the active state of a LIMIT stop command has been detected.
When STBY = 0 and DWIVE = 0, the pulse output has been finished by a LIMIT stop command.
0 : This bit is cleared when the next general-purpose command involving pulse output is executed.
◆ Executing MAWCAL SCAW drive also clears the bit.
◆ If LIMIT stop is performed during CWIWIW drive, the bit is cleared when the next process begins.
If a LIMIT stop command is detected during 2-axis interpolation drive, XLSEWD and YLSEWD are both set to 1.
◆
LIMIT stop commands includes the CWLM and CCWLM signals for which the input function is set for LIMIT
◆
slow stop or LIMIT immediate stop, and SCFT LIMIT position stop by the SCFT LIMIT function.
* For the SCFT LIMIT function, refer to the separate manual "Technical Data A."
