AL.54 Motor parameter is out of range
Alarm cause Checking method Corrective action
When the motor executes the
PL02 motor parameter automatic
identification function, the motor
resistance (PL47) and inductance
(PL48) are out of range or are
zero, and then this alarm occurs. Check if the motor
resistance (PL47),
inductance (PL48) values
are out of range or are
zero. Check the value of
motor resistance
(PL47) and
inductance(PL48).
AL.55 Motor magnetic field error
Alarm cause Checking method Corrective action
1. The difference between
magnetic field feedback by the Hall
sensor and the control magnetic
field inside the servo is big.
2. Hall sensor three-phase (UVW)
are all high or all low and the
output time is over1ms. 1. Check whether the Hall
sensor is abnormal or
interfered.
2. Check whether there is
interference in the
feedback signal, which
caused pulses leakage. Eliminate the Hall
sensor or feedback
signal problem, and
cycling the power.
AL.57 Feedback pulse is lost
Alarm cause Checking method Corrective action
Activate pulse lost detection, and
after initial Z phase signal output,
the pulse interval number between
every 2 Z phase output signal is
out of the range. 1.Check if the feedback is
normal.
2. Check if the pulse
interval number which
triggered by 2 Z phase
pulse is fixed value or not. 1.Eliminate
feedback abnormal.
2. Set correct pulse
number to PL39,
PL40.
