b0
READY/BUSY
Turns ON when the 20SSC-H is ready for a START command
after normal completion of positioning, or when recovering
from an error.
Bit
-
b1
Outputting pulses for forward rotation.
Turns ON while pulses for forward rotation are output.
b2
Outputting pulses for reverse rotation.
Turns ON while pulses for reverse rotation are output.
b3
Completion of zero return operation.
Turns ON upon completion of mechanical zero return
operation, or when the current position is established by the
absolute position detection system.
Turns OFF at OFF-to-ON transition of a mechanical zero
return command, at power-off (reset), or when an absolute
position is lost during the absolute position detection system.
b4
Current value overflow.
•
This bit is set when the current address value falls outside
the range of 32-bit data
(-2,147,483,648 to 2,147,483,647).
•
Cleared by power-off or when a zero return command
becomes active.
b5
Occurrence of an error.
•
This bit is set upon occurrence of an error from the
20SSC-H or the servo amplifier.
•
Cleared when an error reset command becomes active.
→
For details on the statuses at occurrence of errors,
refer to Section 13.2
b6
Completion of positioning.
This bit is set upon normal completion of positioning.
*1
Cleared when a START command becomes active, an error
occurs, or an error reset command becomes active. When the
20SSC-H is stopped by a STOP command, the bit is kept in
OFF status.
b7
Ready and waiting for remaining travel after stopping.
This bit is set when the 20SSC-H goes into a standby state for
the remaining travel upon a STOP command.
Cleared by a START command, or when the remaining travel
operation is canceled.
→
For details on the stop command, refer to Section 7.4
b8
m code is active.
This bit is set when a m code becomes active.
When a m code OFF command is received, the bit is cleared.
→
For details on the m code, refer to Section 10.9
b9
The unit is ready.
This bit is set upon completion of 20SSC-H boot-up after
power-on.
(It is kept in ON state until the power is turned off.)
All buffer memory values become valid after the bit is set.
b10
Transferring servo parameters is in progress.
This bit is ON state while transferring servo parameters with a
transfer command.
It is automatically cleared upon completion of the transfer.
→
For details on the servo parameters transfer,
refer to Subsection 6.2.3 and Section 7.1
b11
*2
Saving data into flash-memory is in progress.
•
This bit is ON while saving buffer memory data into flash-
memory.
•
When finished storing the data, the bit is cleared.
→
For details on storing buffer memory into flash-
memory, refer to Subsection 6.2.1 and Section 7.1
