Separate Serial Pulse Coder Communication Alarm

Hva betyr Alarm 8 ?

This alarm signifies incorrect serial communication with the separate serial pulse coder. It can be caused by noise (specifically if CRC or STBB occurs). If the alarm is issued continuously after power is turned on and noise measures are taken, the pulse coder, the amplifier's control board (α i series), or the pulse module (α i series) may be defective.

• Communication error with the separate serial pulse coder (encoder).
• The encoder is not sending data, or data is corrupted.
• Incorrect communication settings (e.g., baud rate, address) for the encoder.
• Cable fault or loose connection to the encoder.

1. 1

   Check whether the cable connection for the separate serial pulse coder is correct and whether there is a line disconnection.

2. 2

   If CRC or STBB occurs, take noise-preventive measures.

3. 3

   If the alarm is always issued after power is turned on and noise measures have been taken, consider replacing the pulse coder, the control board of the amplifier (α i series), or the pulse module (α i series).
