AL05C Motor position feedback error
Checking method
and corrective action
1.
Check if the feedback signal is abnormal. Use the software scope and select
Feedback position [PUU] as the input signal for the channel and sample at
16 kHz or 20 kHz, and then operate the motor manually to monitor whether
the feedback value has discontinuous sudden jumps.
2.
Check if the feedback signal is interfered, causing sudden jumps to the motor
position feedback.
3.
Check if the communication error rate is increased due to interference. For
example, check the communication error rate by setting P0.017 to -80 and
monitor whether the value of P0.009 is not 0 and continuously increases.
How to clear the
alarm?
Cycle power on the servo drive.
AL060 Absolute position is lost
Trigger condition
and cause
Condition: losing the recorded number of revolutions because of low battery
voltage or loss of power.
Cause:
1.
Voltage level of the battery is too low.
2.
The battery is replaced when the main power of the servo drive is off.
3.
The battery is not installed when the absolute function is enabled.
4.
Poor connection or disconnection of the battery power circuit.
Checking method
and corrective action
1.
Check if the battery voltage is below 2.9V. Re-establish the absolute origin
coordinate after replacing the battery.
2.
Do not replace or remove the battery when the servo drive’s main power is off.
3.
Follow these instructions:
(a)
Install the battery.
(b)
Check the wiring between the battery box and the servo drive.
(c)
Check the encoder wiring.
4.
Ensure the wiring is correct so that the battery power is supplied to the
encoder and then re-establish the absolute origin coordinate.
How to clear the
alarm?
Connect or reconnect the wiring so that the battery power is supplied to the
encoder and then re-establish the absolute origin coordinate. Refer to Section
10.3.4 Establish the absolute origin coordinate for details.
