AL058 Excessive position deviation after initial magnetic field detection is complete

Condition:

Trigger condition

and cause

1. After the initial magnetic field detection is complete, the servo system then

attempts, but fails to reduce the existing position error.

2. If the controller issues commands when the servo system is not fully settled,

the position error might thus be greater and cannot be reduced.

Cause: the controller issues commands during initial magnetic field detection.

1. Check if the controller has issued a command immediately when it is powered

on. Use the software scope and select “Command Position [PUU]” as the

input signal for the channel to monitor whether there is a command issued. If

Checking method

and corrective

action

so, increase the delay time for the controller to issue the command after it is

powered on.

2. If the controller time sequence cannot be modified due to surge interference or

other factors when the power is on, set P2.088 [Bit 4] to 1 to prohibit the servo

from receiving controller commands during the initial magnetic field detection.

DI.ARST

AL05B Motor type setting does not match

Condition: incorrect setting of PM.000.

Cause:

Trigger condition

and cause

1. A Delta motor is connected to CN2 as the main encoder, but PM.000 is not set

to 0.

2. A Delta motor with magnetic encoder is used, but PM.000 or PM.003 is set

incorrectly.

1. Check the setting of PM.000.

Checking method 2. Make sure the type of motor used complies with the setting of PM.000.

and corrective action 3. If a Delta motor with magnetic encoder is used, set PM.000 to 0 and PM.003

to 0x1XX2.

How to clear the

alarm?

Cycle power on the servo drive.
