Hardware error diagnostics

Hardware errors are logged via a collective diagnostic.
The warning and error thresholds can be found in object 0xF816, “PWM Vendor Data”.
The CoE object 0xFA16 “PWM Diag Data” displays the currently measured values.
Error messages are displayed via the “Dev Error“-LED”, in the process data under “PWM Input Device” via the “PWM-Warning” and “PWM Error” bits, and via the DiagMessages (see the following table).

Diagnostics	CoE values	Process data	DiagMessages
Dev error-LED lights up red
Warning External supply voltage is too low	Currently measured value “External Supply Voltage” 0xFA16:13 < 4.75 V, warning threshold 0xF816:14 “External Supply Voltage Warning Level”	0xF616:06 “PWM Warning” = TRUE	0x4601 Warning External supply undervoltage
Warning Overtemperature	Currently measured value “PCB Temperature” 0xFA16:12 > 80.0°C, warning threshold 0xF816:12 “PCB Temperature Warning Level”	0xF616:06 “PWM Warning” = TRUE	–
Error External supply voltage is too low/missing	Currently measured value “External Supply Voltage” 0xFA16:13 < 4.5 V, error threshold 0xF816:15 “External Supply Voltage Error Level”	0xF616:07 “PWM Error” = TRUE	0x8601 Error External supply undervoltage
Error Overtemperature	Currently measured value “PCB Temperature” 0xFA16:12 > 100.0°C, error threshold 0xF816:13 “PCB Temperature Error Level”		–
Error Supply voltage Up is too low or missing	No supply voltage or insufficient supply voltage “Up Supply voltage available” 0xFA16:03 = FALSE		0x810B Error Undervoltage Up
Error Output hardware error Possible causes: - Overcurrent - Short circuit - Undervoltage - Overtemperature	–		0x8144 Error Output hardware error (Trigger a reset to clear the error)
The Dev error-LED is not lit
There are no warnings or error messages.	The values are within the acceptable range.	0xF616:06 “PWM Warning” = FALSE, 0xF616:07 “PWM Error” = FALSE	–
