SD20-G Series
336
AL-02 Overvoltage
Input voltage is too high Check input voltage.
Load rotary inertia too large
Prolong deceleration time
Add external braking resistor
Reduce load.
Increase drive capacity.
AL-03 Undervoltage Input voltage is low
Check input voltage.
Check whether main circuit is
powered on.
AL-04 Hardware fault Hardware fault Contact with Parker.
AL-05
Electric angle
recognition error
Motor line sequence error
Adjust line sequences, exchange
two of them.
AL-06 Overload
Servo motor or encoder wiring is
bad. Check the wiring of servo motor
and encoder.
Machanical factors
Check the transmission ratio of
mechanical equipments.
Servo drive runs when
electromagnetic brake is not released Check the wiring of
electromagnetic brake.
Heavy load
Reduce load.
Increase capcity of drive.
AL-07 Overspeed
Servo motor rotary speed is higher
than max speed Servo motor wiring, encoder
wiring or mechanical fault.
AL-08 Reserved
AL-09
Large position
control error
U, V, W or encoder connection error
or connector contact is bad
Improve connection.
Servo Drive gain is low.
Increase gain, adjust gain of
speed and position
The frequency of position pulse is too
high Reduce pulse frequency or adjust
electronic gear
AL-10 Encoder fault
Disconnected encoder or servo motor
is locked-rotor
Check encoder connection
Servo motor fault
Power on again, if alarm still
occurs, please contact with
Parker.
AL-11 Emergency stop
Logic of ESP input terminal is not
corresponding to connection. Check connection or modify
terminal logic.
Hardware damage of ESP input
terminal Set the function to other input
terminal or contact with Parker.
AL-12
Servo drive
overheat
Enviroment temperature is too high Improve ventilation.
Dirty radiator
Clean air outlet and cooling
radiator.
Foreign matter in fan Clear fan.
Fan damage Exchange fan.
