Message Description
460 n AXIS : FSSB DISCON-
NECT
FSSB communication was disconnected
suddenly. The possible causes are as fol-
lows:
1) The FSSB communication cable is dis-
connected or broken.
2) The power to the amplifier dropped sud-
denly .
3) The amplifier issued a low--voltage
alarm.
461 n AXIS : ILLEGAL AMP IN-
TERFACE
Both axes of a 2--axis amplifier were as-
signed to the fast type interface.
462 n AXIS : SEND CNC DATA
FAILED
Because of an FSSB communication error , a
slave could not receive correct data.
463 n AXIS : SEND SLAVE DATA
FAILED
Because of an FSSB communication error ,
the servo system could not receive correct
data.
464 nAXIS:WRITEIDDATA
FAILED
An attempt to write maintenance information
on the amplifier maintenance screen failed.
465 n AXIS : READ ID DATA
FAILED
At power--up, initial amplifier ID information
could not be read.
466 n AXIS : MOTOR/AMP COM-
BINATION
The maximum current value of the amplifier
does not match the maximum current value
of the motor.
467 n AXIS : ILLEGAL SETTING
OF AXIS
The following servo functions are not en-
abled even when an axis using a DSP ex-
clusively is set on the axis setting screen:
1) Learning control (bit 5 of parameter No.
2008 = 1)
2) High--speed current loop (bit 0 of param-
eter No. 2004 = 1)
3) High--speed interface axis (bit 4 of pa-
rameter No. 2005 = 1)
