288 HVAC Drive H300
Issue Number: 3
13.4 Trips, Sub-trip numbers
Table 13-3 Trip indications
Trip Diagnosis
An Input 1 Loss Analog input 1 current loss
28
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
• 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
29
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
• 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
219
The zero offset calibration of one or both of the analogue outputs has failed. This indicates that the drive hardware has
failed or a voltage is applied to the output via a low impedance, possibly due to a wiring error. The failed output can be
identified by the sub-trip number.
Recommended actions:
• Check the wiring associated with analog outputs
• Remove all the wiring that is connected to analog outputs and perform a re-calibration by power cycling the drive.
• If trip persists replace the drive
App Menu Changed Customization table for an application module has changed
217
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.
If more than one menu has changed the lowest menu has priority. Drive user parameters must be saved to prevent this trip
on the next power-up.
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
11
The drive has tripped during an autotune. The cause of the trip can be identified from the sub-trip number.
Recommended actions:
• Ensure the motor is free to turn i.e. mechanical brake was released
• Ensure Pr 03.026 is set correctly (or appropriate 2
nd
motor map parameter)
• Check feedback device wiring is correct
• Check encoder mechanical coupling to the motor
Sub-trip Reason
1 Output 1 failed (Terminal 9)
2 Output 2 failed (Terminal 10)
Sub-trip Reason
1 Menu 18
2 Menu 19
3 Menu 20
Sub-trip Reason
1 The position feedback did not change when position feedback is being used during rotating autotune.
2 The motor did not reach the required speed during rotating autotune or mechanical load measurement.
