Troubleshooting

AL127 PDO object is write-protected when servo drive is on

Trigger condition

and cause

PDO object is write-protected (unchangeable) when the servo drive is on.

Checking method Make sure no specified object is written when the servo drive receives or sends

and corrective action the PDO in the Servo On state.

How to clear the

alarm?

NMT: reset node, OD 6040h [Bit 7] (Fault reset), or DI.ARST.

AL128 Error occurs when PDO object is read from EEPROM

Trigger condition An error occurs when the default value is loaded from ROM at start-up.

and cause

All objects are automatically restored to default values.

Checking method Check if an error occurs because the specified object is read from EEPROM when

and corrective action the servo drive receives or sends the PDO.

AL129 Error occurs when PDO object is written to EEPROM

Trigger condition

and cause

An error occurs when the PDO object is written to EEPROM.

Checking method Check if an error occurs because the specified object is written to EEPROM when

and corrective action the servo drive receives or sends the PDO.

How to clear the

alarm?

NMT: reset node, OD 6040h [Bit 7] (Fault reset), or DI.ARST.

AL130 Accessing address of EEPROM is out of range

Trigger condition

and cause

The amount of data in the ROM is greater than the allowable space specified by

the firmware. It is probably because the firmware has been updated, but the data

in the ROM was stored by the previous firmware version.

Checking method Check if the specified object causes the accessing address in EEPROM exceeds

and corrective action the range when the servo drive receives or sends the PDO.

How to clear the

alarm?

NMT: reset node, OD 6040h [Bit 7] (Fault reset), or DI.ARST.

AL131 EEPROM CRC calculation error

Trigger condition The data in ROM is damaged. All objects are automatically restored to default

and cause

values.

Checking method

and corrective action

Check if the specified object causes a CRC calculation error in EEPROM when the

servo drive receives or sends the PDO. Usually, this alarm is caused by an error in

DSP.

How to clear the

alarm?

NMT: reset node, OD 6040h [Bit 7] (Fault reset), or DI.ARST.
