Command Rotate controller Linear controller
RA Query the Runaway status for the actual motion controller. Valid for both
motion controllers as each one individually may activate a Runaway output
which removes motor power.
If Runaway is not active, the response will be:
No runaway, mask = 0x8467
(the value for ‘mask’ differs for the two motion controllers and may also
differ for different software versions).
If Runaway is active, the response will comprise a cause code:
RUNAWAY, cause code = 0x0020, mask = 0x8467
The cause code is bitmapped, i.e. there may be more than one cause present
at the same time. The interpretations of the individual bits are:
RA_X_ENC_ERROR 0x0001 The position readings from the
absolute and the incremental
encoders for the X axis differ too
much
RA_Y_ENC_ERROR 0x0002 Same for the Y axis
RA_Z_ENC_ERROR 0x0004 Same for the Z axis
RA_LOST_SYNC_
ERROR 0x0020 Checksum error on 3 consecutive
messages on the serial link used for
communication between the two
motion controllers. Happens if one
of the motion controllers stops
responding
RA_TIMEOUT 0x0040 The linear controller has not
received synchronization messages
from the rotate controller at the
required regular interval
RA_X_ILL_MOVE 0x0100 The X axis has moved when it is not
expected to
RA_Y_ILL_MOVE 0x0200 Same for the Y axis
RA_Z_ILL_MOVE 0x0400 Same for the Z axis
RA_TRAP 0x4000 The micro controller has encounterd
an illegal instruction
VERSION Print the boot message including software version (see the section Boot
prompt on page 5-28)
SSCTX Transmit a message on the high-speed serial link used for communication
between the two controllers.
Do not use unless you receive further instructions
BAUD Change the baud rate of the interface. Remember to change the terminal
baud rate immediately afterwards
