A parameter(*) has been
specified incorrectly.
Check the following param-
eters(*):
No.030: Is the specified
motor type cor-
rect?
No.031: Is the specified
direction of rota-
tion of the motor
correct?
No.106: Is the denominator
of the number of
pulses per single
revolution of the
motor 0?
No.180: Is the specified
reference counter
capacity 0 or a
negative value?

A DO alarm is issued. Replace the servo amplifier
unit.
423
The specified speed
exceeds 32767000 detec-
tion units per second.
Re–examine the CMR and
speed settings.
425
The cooling fan has
stopped.
This alarm is issued when
the fan motor built into the
servo amplifier unit has
failed.
The fan motor is consum-
able.
(1) Check that the fan is not clogged with foreign matter.
(2) Check that the power connector of the fan is connected
properly.
(3) Replace the fan or servo amplifier unit.
446
The external pulse input line
is disconnected.
Connect the external pulse
input signal correctly.
447
The velocity deviation is too
high (velocity control)
Check the actual velocity.
See the settings of parame-
ter(*) 136.
