46, RS-485 ETX FAULT DETECTED
A slave controller can generate this error message if the command received
by it is incomplete; the number of bytes transmitted by a master controller do
not match the number of bytes received by the slave controller.
A master controller can generate this error message if the response received
by it is incomplete; the number of bytes transmitted by a slave controller do
not match the number of bytes received by the master controller.
NOTE: Check for (a) improper RS-485 cable connection, (b) controller
address conflict, or (c) prohibited multiple master configuration.
47, RS-485 CRC FAULT DETECTED
A slave controller can generate this cyclical redundancy check (CRC) error
message if a checksum verification of the command received by it does not
match the checksum computed by master controller.
A master controller can generate this cyclical redundancy check (CRC) error
message if a checksum verification of the response received by it does not
match the checksum computed by slave controller.
NOTE: Check for (a) improper RS-485 cable connection, (b) controller
address conflict, or (c) prohibited multiple master configuration.
48, CONTROLLER NUMBER OUT OF RANGE
The controller number prefix is out of range.
49, SCAN IN PROGRESS
This error message is generated if “SC” or “SC?” commands are received by
a controller while a scan is already in progress.
7.2 Axis-Specific Error Messages
Where (“x” = 1 to 4)
x00, MOTOR TYPE NOT DEFINED
A motion command has been issued to the controller before specifying a
motor type. Enable auto motor detection by setting bit# 0 in configuration
register to 0 (refer ZZ command) or set valid motor type (refer QM
command).
x01, PARAMETER OUT OF RANGE
The parameter sent along with a command is out of range.
x08, MOTOR NOT CONNECTED
The controller has detected that there is no motor connected to the axis that is
either being commanded to move or is already in motion.
