Alarm Meaning
The setting of Pn212 (Num-
ber of Encoder Output
Pulses) or Pn281 (Encoder
Output Resolution) is outside
of the setting range or does
not satisfy the setting condi-
tions.
The combination of some
parameters exceeds the set-
ting range.
The settings of the Option
Module and Pn002 =
n.X (External Encoder
Usage) do not match.
The capacities of the SER-
VOPACK and Servomotor do
not match.
An unsupported device was
connected.
The connected motor is a dif-
ferent type of motor from the
previously connected motor.
The setting of Pn282 (Linear
Encoder Scale Pitch) has not
been changed from the
default setting.
The /S-ON (Servo ON) signal
was input from the host con-
troller after a utility function
that turns ON the Servomo-
tor was executed.
An overcurrent flowed
through the power trans-
former or the heat sink over-
heated.
The current to the motor
exceeded the allowable cur-
rent.
There is an error related to
regeneration.
A regenerative overload
occurred.
• The AC power supply input
setting or DC power supply
input setting is not correct.
• The power supply wiring is
not correct.
The main circuit DC voltage
is too high.
The main circuit DC voltage
is too low.
The motor exceeded the
maximum speed.
