SD20-G Series
337
Improper installation of drive, such as
poor ventilation or wrong install
direction.
Install as required.
Too heavy load
Discharge energy is too large
AL-13 Input phase loss
Phase loss with input phase Check input power supply.
Use single-phase power supply. Check parameter setting
AL-14
Regenerative
braking error
Wrong braking resistor parameter Change parameter.
Continuous brake time is too long
Check load, servo only can drive
non-potential energy load.
AL-16
Repeat setting of
input terminal
Repeat setting of input terminal Reset input terminal.
AL-17
Disconnected
encoder cable
Disconnected encoder cable
Disconnected or damage of
encoder cable
AL-18
Rotary inertia
recognition fault
Rotary inertia recognition fault Turn up Po013 manually.
AL-19
Alarm of encoder
battery
Alarm of encoder battery
1. Check if encoder cable is
connected well.
If it is disconnected, reconnect it
and reset alarm.
2. Check if battery level is 3.6V. If
level is lower than 3.2V, keep
control power at” ON” state,
3. Shield AL-19:
So-38=1
，
So-43=1 reset alarm.
4. Check if connecton of battery is
reliable.
AL-20
Uninitialized
E2ROM
Unintialized E2ROM of servo motor
Servo motor encoder is not
initialized, please study motor
angle manually.
AL-21 Large zero drift Servo drive zero drift is too large
Check wiring or parameter
setting.
AL-22 Z signal lost
Z signal is not detected after encoder
rotates 3 times continuously. Check encoder and Z signal
cable.
AL-23 Reserved
AL-24
Encoder battery
undervoltage
Encoder battery undervoltage
1. If encoder battery is
undervoltage, AL-24 will occur
leading to enoder position loss.
Reset mechanical origin to
eliminate.
2. Shield AL-24:
So-48=1
，
So-41=1(set current
position as machnical origin),
So-43=1 reset alarm, PC/PLC will
reset the mechanical origin.
AL-25 Motor overheat Motor temperature is too high. Improve ventilation
