171
In the panel window, the error numbers follow E in the display.
Error No. Error name Description, action, etc.
B00 SCHA setting error The setting of SCHA command is invalid.
B01 TPCD setting error The setting of TPCD command is invalid
B02 SLEN setting error The setting of SLEN command is invalid.
B03 Home-return method error The setting of “Axis-specific parameter No. 10,
Home-return method” is invalid.
(Not incremental encoder AND current position 0 home is
specified, etc.)
B04 1-shot-pulse output excessive
simultaneous use error
The number of BTPN and BTPF timers operating in one
program simultaneously exceeds the upper limit (16).
B05 Estimate-stroke over error at
home return
The operation at home return exceeded the estimate
stroke.
B0E ABS encoder multi-rotation error [Detail & Cause]
The multi-rotation of the encoder is inconstant. There is a
concern that the absolute reset has not been conducted or
the absolute data has been lost.
[Countermeasure]
Conduct the absolute reset.
B0F ABS encoder counter overflow
error
[Detail & Cause]
The multi-rotation counter on the encoder has exceeded
the upper limit.
[Countermeasure]
Check such a thing as if the soft limit of Axis Specific
Parameter No. 7 and 8 are set to encoder and the multiple
rotation count is in the available range.
B10 Z-phase search timeout error Z-phase cannot be detected. Check in restriction on
operation, wiring, motor, and so on.
B11 Home position sensor escape
timeout error
Escape from the home position sensor cannot be
confirmed. Check in restriction on operation, wiring, motor,
home position and so on.
B12 Storage variable number error for
SEL command return code
Storage variable number error for SEL command return
code
B15 Input-port debug filter type error The setting of input-port debug filter type is invalid.
B16 SEL operand specification error The operand specification of SEL command is invalid
B17 Parameter register busy error at
issuance of slave command
The driver special command ACK generated a timeout at
issuance of a slave command.
B18 Device number error The device number is invalid.
B19 Unit type error The unit type is invalid
B1A ABS reset indication error There is an error in the selection in the ABS reset.
(Ex: Simultaneous selection of two or more axes, or
selection of the axis except for that of the ABS encoder,
the version of the PC software or teaching pendant is old,
etc.)
B1B Ethernet non-closed socket open
error
An attempt was made to open a socket without closing it
first.
B1C Ethernet in-use-by-other-task
error
An attempt was made to open a channel already opened
by other task.
B1D Ethernet non-open error An attempt was made to use a channel not opened by
own task.
B1E Ethernet multiple WRIT execution
error
WRIT commands were executed simultaneously in
multiple tasks for the same channel, or a WRIT command
had failed (due to a communication error, etc.) and then
was retried without executing a CLOS command → OPEN
command first.
