Servo Module Mounting Error

Hva betyr 924 ?

This alarm indicates that a servo module within the Fanuc Series 20 CNC system is either incorrectly mounted, not detected, or has a communication issue related to its physical connection. This prevents proper initialization and operation of the servo axis.

• Servo amplifier module incorrectly seated in its backplane or rack.
• Loose or damaged communication link (e.g., serial or bus cable) between the servo module and the main control unit.
• Faulty servo module or backplane connector.
• Dust or debris obstructing electrical contacts.
• Incorrect module configuration for the system.

1. 1

   Power off the CNC system completely and inspect the servo amplifier modules. Reseat them firmly into their respective slots or backplane connectors.

2. 2

   Check all interconnecting cables (e.g., fiber optic links, bus cables) between the servo modules and the CNC for proper connection and physical integrity.

3. 3

   Clean the module connectors and backplane contacts with a suitable electronic contact cleaner to ensure good electrical contact.

4. 4

   Verify that the correct type and number of servo modules are installed according to the machine's configuration.

5. 5

   If the alarm persists, try swapping the suspected servo module with a known good one from another axis or a spare.
