Analog Input 1 Wire Breakage

What does sd5 mean?

A wire breakage has been detected on analog input 1, specifically when the current on the input is less than 4 mA for a 4-20 mA setpoint range. This indicates an open circuit in the analog signal path. Loss of this input means the drive will not receive its commanded setpoint, potentially leading to incorrect speed or torque.

Steps 1–2 are listed in Priority Fix.

1. 3

   Check the external device providing the 4-20 mA signal for proper operation and output.
