When switching the
motor type, if the
setting value exceeds
the range of PM-00,
this alarm will occur.
Check if the parameter is

E320A represents P2-10;

The parameter setting range of
linear motor is different from
rotary motor. Please setup the
correct parameter according to
the motor type.
：
Motor parameter is not confirmed
Causes
Checking Method
Corrective Actions
When enabling the Y
item of PM-09, servo
will detect the motor’s
current magnetic field,
and compare it with the
position of Hall
sensor’s. When the
deviation between both
is too excessive, this
alarm will occur.
The servo drive monitors
motor
’
s magnetic field through
the encoder, thus,
1. check if the feedback of
encoder interferes the pulse
loss because of the noise.
2. assume that the feedback type
of the encoder is square wave
digital signal, check if the
motor is over speed and
exceeds the limit that
hardware could take. The limit
is 20Mhz (the resolution of
quardruple frequency)
3. check if Hall sensor is normal.
1. Exclude the noise problem, if
the type is square wave digital
signal, users could filter out
the noise through the proper
setting of filter function.
The setting of converter box
=>PM-03
The setting of CN5 =>P1-74
2 Limit the max. speed of motor.
Setup P1-55.
：
Feedback pulse is lost

Corrective Actions
When P2-81 = 1, it will
check if pulse is lost. If
the pulse loss amount
exceeds the value of
P2-82, this alarm will
occur.
1. Check if the feedback of
encoder interferes the pulse
loss because of the noise.
2. Assume that the feedback type
of the encoder is square wave
