5134 FSSB : OPEN READY TIME
OUT
Initialization did not place FSSB in the
open ready state.
5135 FSSB : ERROR MODE FSSB has entered error mode.
5136 FSSB : NUMBER OF AMPS
IS SMALL
In comparison with the number of con-
trolled axes, the number of amplifiers rec-
ognized by FSSB is not enough.
5137 FSSB : CONFIGURATION
ERROR
FSSB detected a configuration error.
5138 FSSB : AXIS SETTING NOT
COMPLETE
In automatic setting mode, axis setting has
not been made yet.
Perform axis setting on the FSSB setting
screen.
5139 FSSB : ERROR Servo initialization did not terminate nor-
mally. The optical cable may be defective,
or there may be an error in connection to
the amplifier or another module. Check the
optical cable and the connection status.
5155 NOT RESTART PROGRAM
BY G05
During servo leaning control by G05, an at-
tempt was made to perform restart opera-
tion after feed hold or interlock. This restart
operation cannot be performed. (G05 lean-
ing control terminates at the same time.)
5156 ILLEGAL AXIS OPERATION
(AICC)
(M series)
In AI contour control mode, the controlled
axis selection signal (PMC axis control)
changes.
In AI contour control mode, the simple syn-
chronous axis selection signal changes.
ILLEGAL AXIS OPERATION
(AICC)
(21i–M)
In AI advanced preview control mode, the
controlled axis selection signal (PMC axis
control) changes.
In AI advanced preview control mode, the
simple synchronous axis selection signal
changes.
5157 PARAMETER ZERO
(AICC)
(M series)
Zero is set in the parameter for the maxi-
mum cutting feedrate (PRM1422, 1432).
Zero is set in the parameter for the accel-
eration/deceleration before interpolation
(PRM1770, 1771).
Set the parameter correctly.
5195 DIRECTION CAN NOT BE
JUDGED
(T series)
When the touch sensor with a single con-
tact signal input is used in the direct input
B function for tool offset measurement val-
ues, the stored pulse direction is not
constant. One of the following conditions
exists:
· The stop state exists in offset write
mode.
· Servo off state
· The direction varies.
· Movement takes place simultaneously
along two axes.
5196 ILLEGAL OPERATION
(HPCC)
(M series)
Detach operation was performed in HPCC
mode. (If detach operation is performed in
HPCC mode, this alarm is issued after the
currently executed block terminates.)
5197 FSSB : OPEN TIME OUT The CNC permitted FSSB to open, but
FSSB was not opened.
