Message Description
5134 FSSB : OPEN READY TIME
OUT
The FSSB did not become ready to open
during initialization.
5135 FSSB : ERROR MODE The FSSB entered an error mode.
5136 FSSB : NUMBER OF AMPS
IS SMALL
The number of amplifiers recognized by the
FSSB is insufficient, compared with the
number of controlled axes.
5137 FSSB : CONFIGURATION
ERROR
The FSSB detected a configuration error.
5138 FSSB : AXIS SETTING NOT
COMPLETE
Axis setting has not been performed in auto-
matic setting mode. Perform axis setting
using the FSSB setting screen.
5139 FSSB : ERROR The servo system could not be initialized
normally. The cause may be an optical
cable failure or incorrect connection with an
amplifier and other modules.
5197 FSSB : OPEN TIME OUT The FSSB did not open when the CNC had
allowed the FSSB to open.
5198 FSSB : ID DATA NOT READ The initial ID information for the amplifier
cannot be read because of a failure in the
temporary assignment.
5311 FSSB : ILLEGAL CONNEC-
TION
A connection related to FSSB is illegal.This
alarm is issued when either of the following
is found:
1 Two axes having adjacent servo axis
numbers (parameter No. 1023), odd
number and even number, are assigned
to amplifiers to which different FSSB
systems are connected.
2 The system does not satisfy the require-
ments for performing HRV control, and
use of two pulse modules connected to
different FSSB systems having different
FSSB current control cycles is speci-
fied.
