AL018 Encoder output error
Checking method
and corrective action
1.
The settings of P1.076 and P1.046 should follow these requirements:
P1.076 > motor speed and
Motor speed
60
× P1.046 × 4 < 19.8 × 10
6
2.
Check the communication error rate by setting P0.002 to -80. If this value
continues to accumulate, it means there is interference. Check the following
items:
(a)
Check if the motor is properly grounded. Make sure the power cable
(green end) is grounded to the servo drive heat sink.
(b)
Check if the connection for the encoder signal cable is normal.
Make sure the encoder signal cable is separated from the power supply
or any high-current cables to avoid interference.
(c)
Use a shielded cable for the encoder, pull out the shielded mesh, and
ground it.
3.
Check the fault record (P4.000 - P4.004) and see if an alarm has occurred
(AL011, AL024, AL025, or AL026). Use the checking methods and corrective
actions to clear the alarm if any of them occurs.
4.
If you do not need to use the OA/OB pulse, set P2.065 [Bit 13] to 1 to disable
the detection function for encoder output error (AL018).

AL020 Serial communication timeout
Trigger condition
and cause
Condition: RS-485 communication error.
Cause:
1.
Improper parameter setting for P3.004 (Modbus communication timeout).
2.
Servo drive has not received the communication command for a long time and
has timed out (refer to P3.004).
Checking method
and corrective action
1.
Check and correctly set the value for the communication timeout parameter.
2.
Check if the communication cable is loose or broken and make sure it is
correctly wired.

AL022 RST leak phase
Trigger condition
and cause
Condition: RST power cable is loose or there is no power. The error type of AL022
is a warning by default. To set AL022 as an alarm, you can set P2.066 [Bit 12] to 1.
Cause: RST leak phase.
