Trips, Sub-trip numbers

Table 13-4 Trip indications
Trip
An Input 1 Loss Analog input 1 current loss
An Input 1 Loss trip indicates that a current loss was detected in current mode on Analog input 1 (Terminal 5, 6). In 4-20 mA
and 20-4 mA modes loss of input is detected if the current falls below 3 mA.
Recommended actions:
• Check control wiring is correct
28
• Check control wiring is undamaged
• Check the Analog Input 1 Mode (07.007)
• Current signal is present and greater than 3 mA
An Input 2 Loss Analog input 2 current loss
An Input 2 Loss indicates that a current loss was detected in current mode on Analog input 2 (Terminal 7). In 4-20 mA and
20-4 mA modes loss of input is detected if the current falls below 3 mA.
Recommended actions:
• Check control wiring is correct
29
• Check control wiring is undamaged
• Check the Analog Input 2 Mode (07.011)
• Current signal is present and greater than 3 mA
An Output Calib

Analog output calibration failed

The An output Calib trip indicates that one or both of the Analog outputs have failed during the zero offset calibration. The
failed output can be identified by the sub-trip number.
Sub-trip
219
Recommended actions:
• Check the wiring associated with analog outputs
• Remove all the wiring that is connected to analog outputs and perform the calibration
• If trip persists replace the drive
App Menu Changed

Customization table for an application module has changed

The App Menu Changed trip indicates that the customization table for an application menu has changed. The menu that
has been changed can be identified by the sub-trip number.
Sub-trip
217
Recommended actions:
• Reset the trip and perform a parameter save to accept the new settings
Autotune 1 Position feedback did not change or required speed could not be reached
The drive has tripped during an autotune. The cause of the trip can be identified from the sub-trip number.
Sub-trip
11
Recommended actions:
• Ensure the motor is free to turn i.e. mechanical brake was released
• Ensure Pr 03.026 and Pr 03.038 are set correctly (or appropriate 2
• Check feedback device wiring is correct
• Check encoder mechanical coupling to the motor
