System Alarm: Communication or Parameter Setting Error

¿Qué significa Alarm 4 ?

This alarm can indicate two primary issues depending on the set bits. If DTE, CRC, and STB bits are set, it signifies a communication alarm in the serial pulse coder, potentially due to noise, cable issues, or defective hardware. If the PRM bit is set, it indicates an invalid parameter setting detected by the servo software.

• A communication failure has occurred between system components.
• Incorrect or invalid parameters have been loaded into the system.
• The connected device (e.g., PLC, HMI) is not responding.
• A bus error has been detected on the control network.

1. 1

   If DTE, CRC, and STB bits are set, verify the physical cable connection for the serial pulse coder and check for any line disconnections.

2. 2

   If DTE, CRC, and STB bits are set, implement thorough noise-preventive measures. If the alarm persists continuously after power-on, consider replacing the pulse coder, the control board of the amplifier (α i series), or the pulse module (α i series).

3. 3

   If the PRM bit is set, investigate the cause of the invalid parameter setting according to Subsection 2.1.5, "Actions for Invalid Servo Parameter Setting Alarms."
