BUSY BIT
: When this bit is 0, it indicates that writing a command to the corresponding axis is enabled.
When this bit is 1, it indicates that the corresponding axis is in the driving status or in the
data processing status. The command is ignored. A command must be written after confirming
BUSY BIT=0.
However, special commands(refer to the paragraph 6-2) can be written even when BUSY BIT=1.
DRIVE BIT : When this bit is 1, it indicates that the corresponding axis is in the driving status.
DREND BIT : When this bit is 1, it indicates that the drive of the corresponding axis has been terminated
(Note 1,3). Judge the termination of driving when multiple control.
This bit is reset by writing the next command.
ERROR BIT : This bit indicates that the written command is undefined or has a data error(Note 1,3).
You can check description of the error using the ERROR STATUS READ Command.
This bit is reset by writing the next command.
MAN BIT
: This bit is not used on this product. 0 is output (Note3).
LSEND BIT : When DRIVE BIT=1, it indicates a valid CWLM or CCWLM signal has been entered.
When DRIVE BIT=0, it indicates pulse output has been stopped by CWLM or CCWLM signal
(includes the output stopped by an applied function SOFT LIMIT).
This bit is reset at start of the next drive (Note2).
SSEND BIT : When DRIVE BIT=1, it indicates the SLOW STOP Command has been entered.
When DRIVE BIT=0, it indicates pulse output has been stopped by the SLOW STOP Command.
This bit is reset at start of the next drive (Note2).
FSEND BIT : When DRIVE BIT=1, it indicates the FSSTOP signal or FSSTOP Command has been entered.
When DRIVE BIT=0, it indicates pulse output has been stopped by the FSSTOP signal or
FAST STOP Command. This bit is reset at start of the next drive (Note2).
Note1: It is valid only when BUSY=0.
Note2: Reset by the up edge of the DRIVE signal. Not reset by a command not accompanied by drive.
When the power is turned on or the RESET signal is input, each of DREND, ERROR and MAN bits
Note3:
has an undefined value. So, check only whether BUSY bit is 0, run an NOP command and then
initialize the DREND, ERROR and MAN bits.
