Treatment.
Reasons
Confirmation method
Handling measures
1. Instantaneous dips in control
supply voltage.
◆
Measure the supply voltage.
Set the supply voltage within the
specified range and reset the
manufacturer's parameters.
2. Instant power off during
parameter writing.
◆
Verify if there is power failure
during parameter storage.
Reset the default set.
3. Parameters are written
frequently.
◆
Check if the parameters change
operation is frequently performed by
the upper unit.
It is possible that the Servo is
faulty. Replace the Servo and
change the Parameters writing
method.
4. ac power, grounding and
static noise that can cause
data storage malfunctions.
◆
After initializing the parameters
setting value and resetting the
function code parameters, it still
occurs frequently.
Take measures to prevent noise
disturbance.
5. Servo unit failure
◆
After resetting the function code
parameters
after
multiple
initializations, the corresponding fault
still occurs.
It is possible that the servo is
faulty. Replace the servo.
Error code
ER. 023
MCU and FPGA communication exception
Reason
During the initialization process, the MCBU writes relevant data to a specific address of the FPGA
and then reads the relevant data from the specific address to verify the normal status of the
address bus, data bus and relevant signals between the MCBU and the FPGA.
Treatment.
Reasons
Confirmation method
Handling measures
1. Servo unit failure.
◆
The servo has failed when the power
is turned on several times and the fault is
still reported.
Replace the servo.
Error code
ER. 030
FPGA using backup code
Reason
The FPGA uses a backup code.
Treatment.
Reasons
Confirmation method
Handling measures
1. Was there a firmware update to
the FPGA before this alarm
was generated?
Check if the FPGA firmware has been
upgraded.
If you have, re-update
the relevant firmware.
2. This alarm is generated at power
up
◆
Possible external interference at start-
up causes program loading exceptions
Re-power.
Error code
ER. 040
Parameters setting exception
Reason
The function code Parameters Set value exceeds its specified range.
