10.2 Diagnostics
TM31: Key diagnostic parameters (details in List Manual)
Parameter Name
Description
r0002 TM31 operating display
Operating display for Terminal Board 31 (TB31).
r4021 TM31 digital inputs, terminal actual value
Displays the actual value at the digital input terminals on the TM31. This parameter shows the actual value,
uninfluenced by simulation mode of the digital inputs.
r4022 CO/BO: TM31 digital inputs, status
Displays the status of the digital inputs on the TM31. This parameter shows the status of the digital inputs
under the influence of simulation mode of the digital inputs.
r4047 TM31 digital outputs, status
Displays the status of the TM31 digital outputs. Inversion via p4048 is taken into account.

Indicating and rectifying faults

The device features a wide range of functions that protect the drive against damage if a fault
occurs (faults and alarms).
Indicating faults and alarms
If a fault occurs, the drive displays the fault and/or alarm on the AOP30 operator panel.
Faults are indicated by the red "FAULT" LED and a fault screen is automatically displayed.
You can use the F1 Help function to call up information about the cause of the fault and how
to remedy it. You can use F5 Ack. to acknowledge a stored fault.
Any alarms are displayed by the yellow flashing "ALARM" LED. The system also displays a
note in the status bar providing information on the cause.
Every fault and alarm is entered in the fault/alarm buffer along with time the error occurred.
The time stamp refers to the relative system time in milliseconds (r0969).
Activate the "Set date/time - AOP synchronization -> Drive" setting to date- and time-stamp
errors on the AOP30.
What is a fault?
A fault is a message from the drive indicating an error or other exceptional (unwanted)
status. This could be caused by a fault within the converter or an external fault triggered, for
example, from the winding temperature monitor for the induction motor. The faults are
displayed and can be reported to a higher-level control system via PROFIdrive. In the
delivery condition, the message "Drive fault" is also sent to a relay output. Once you have
rectified the cause of the fault, you have to acknowledge the fault message.
