6 TROUBLESHOOTING
6.2 Troubleshooting for drive unit
*1 After resolving the source of trouble, cool the equipment for approximately 30 minutes.
*2 The following shows three stop methods of DB, EDB, and SD.
DB: Dynamic brake stop (For a servo amplifier without the dynamic brake, the servo motor coasts.)
Coasts for MR-J4-03A6(-RJ) and MR-J4W2-0303B6. Note that EDB is applied when an alarm below occurs;
[AL. 30.1], [AL. 32.2], [AL. 32.4], [AL. 51.1], [AL. 51.2], [AL. 888]
SD: Forced stop deceleration
EDB: Electronic dynamic brake stop (available with specified servo motors only)
Refer to the following table for the specified servo motors. For other than the specified servo motors, the stop method of DB is applied.
*3 This is applicable when [Pr. PA04] is set to the initial value. The stop method of SD can be changed to DB with [Pr. PA04].
*4 The alarm can be canceled with the following settings:
When the fully closed loop control mode is selected: Set [Pr. PE03] to "1 _ _ _".
When a linear servo motor or a direct drive motor is used: Set [Pr. PL04] to "1 _ _ _".
*5 In some controller communication status, the alarm factor may not be removed.
*6 This alarm occurs only in the J3 compatibility mode.
*7 Reset alarms while all the safety observation functions have stopped.
