CPU chip is damaged, replace the servo
amplifier.
AL-14
Emergency
stop
Emergency stop signal is
effective
See if port,
setting of emergency stop function, signal
contact is in a normally closed state (ON)
AL-15
Abnormal
driving ban
Ccwl or.cwl to OFF state
1:
Check CCWL,.cwl
wiring, the signal contact is in a normally
closed state (ON).
2
If do not use the driving ban
function, can set pn006 parameters, to block
it.
AL-16
Brake
average
power
overload
The input voltage is too
high or braking load rate
above 85%
1
Using the monitoring mode to see if
the input voltage is beyond the normal range
2
Reduce the start-stop frequency
3
External more
powerful regenerative braking resistor
(remove internal brake resistance, not
parallel)
4
Increase the deceleration time
5
Renewable power resistance value and the
resistance value is set correctly
6
Change a more powerful motor and drive
AL-17
Abnormal
encoder signal
frequency
output
Set the encoder
output of frequency
division than not.
Resetting Pn016, Pn017
parameter values, must
satisfy the DA/DB > = 1.
