• Machine struck. • Check the machine.
• Accuracy at initial magnetic pole
detection is bad.
• Review the parameter No.PS09
setting (magnetic pole detection
voltage level).
• Wrong wiring of the servomotor wires
(U, V, and W).
• Correct the wiring.
• Linear encoder resolution differs from
the setting value.
• Review the parameter No.PS02
and PS03 setting (linear encoder
resolution).
• Check the installation of linear
encoder.
• Mismatch of the linear encoder
installation direction.
• Check the installation direction of
linear encoder.

Initial magnetic
pole detection
error
• Magnetic pole detection limit switch is
not on.
• Servo amplifier
power on.
• Multiple CPU
system power on.
• Connect the magnetic detection
limit switch correctly.
• Set the limit switch to forced ON
by the parameter No.PD02
setting. (When the amplifier input
is used in the Motion CPU, do
not set to forced ON since it is
shared with the input signal.)
• The temperature of linear encoder is
high.
• Check the temperature of linear
encoder and contact with the
linear encoder manufacturer.

error 2
• The signal level of linear encoder has
dropped.

• Check the installation of linear
encoder.
