444 n AXIS : INV. COOLING FAN
FAILURE
The cooling fan of the inverter is abnormal.
445 n AXIS : SOFT DISCONNECT
ALARM
The digital servo software detected a broken wire in the pulse coder.
446 n AXIS : HARD DISCONNECT
ALARM
A broken wire in the built–in pulse coder was detected by hardware.
447 n AXIS : HARD DISCONNECT (EXT) A broken wire in the separate detector was detected by hardware.
448 n AXIS : UNMATCHED FEEDBACK
ALARM
The sign of feedback data from the built–in pulse coder differs from
that of feedback data from the separate detector.
449 n AXIS : INV. IPM ALARM IPM (intelligent power module) detected an alarm.
460 n AXIS : FSSB DISCONNECT FSSB communication was disconnected suddenly. The possible
causes are as follows:
1) The FSSB communication cable was disconnected or broken.
2) The power to the amplifier was turned off suddenly.
3) A low–voltage alarm was issued by the amplifier.
461 n AXIS : ILLEGAL AMP INTERFACE The axes of the 2–axis amplifier were assigned to the fast type inter-
face.
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 n AXIS : WRITE ID DATA FAILED An attempt was made to write maintenance information on the ampli-
fier maintenance screen, but it failed.
465 n AXIS : READ ID DATA FAILED At power–up, amplifier initial ID information could not be read.
466 n AXIS : MOTOR/AMP
COMBINATION
The maximum current rating for the amplifier does not match that for
the motor.
467 n AXIS : ILLEGAL SETTING OF
AXIS
The servo function for the following has not been enabled when an
axis occupying a single DSP (corresponding to two ordinary axes) is
specified on the axis setting screen.
High–speed current loop (bit 0 of parameter No. 2004 = 1)
