AL04 Regenerative alarm
Cause
Inspection
Remedy
Brake transistor fault.
Set PC36 to be 0 and re-power on,
if AL04 is occurred soon, it means
the brake transistor broken.
Contact agent for proper service.
Built-in brake resistor or brake
option is disconnected.
Check the wirings.
Correct the wirings.
AL05 Overload 1
Cause
Inspection
Remedy
Operate the servo drive in heavy
duty continually.
Check if mechanism load is huge.
Upgrade the capability of servo or
reduce the duty.
Improper gain values setting.
Check if vibration of mechanism is
occurred.
Re-operate the auto-gain tuning job
to obtain the proper gain value.
Servo system is instable.
Check if acceleration/deceleration
time constant is proper.
Extend these setting values.
Encoder faulty.
As motor shaft is rotated slowly with
Servo OFF, the pulses feedback
should vary in proportion to rotary
angle. If the indication skips or
returns midway, it is faulty.
Contact agent for proper service.
AL06 Over speed
Cause
Inspection
Remedy
Command pulses frequency
exceeded the permissible
instantaneous speed frequency.
Check the frequency of command
pulses whether exceeds the
permissible range.
Set the command pulses frequency
correctly.
Improper acceleration/deceleration
time constant settings.
Check if these values are too small.
Increase acceleration/deceleration
time constant.
Servo system is instable to cause
overshoot.
Observe if the mechanism is with
vibration.
1. Re-set proper servo gain value.
2. If gain could not be set to proper:
1) Reduce load inertia ratio; or
2) Set acceleration/deceleration
time constant to proper value.
