on the display [on the
integrated keypad]
Solution: For configuration errors, check the configuration of the Bus communication, Bus type, Baudrate, address. parameter setting
For communication errors verify wiring, resistance of terminations, interference immunity, timeout settings.
For more details reference should be made to the datasheet of the bus being used.
18 Opt 1 IO fault [OPT1]
Condition: Error in the communication between Regulation and I/O expansion card in slot 1 (Advanced version only).
Solution: Check that it has been inserted correctly, see Appendix section A.1 on ADL300 QS manual (code 1S9QSEN). Advanced version only.
19 Opt 2 IO fault
Condition: Error in the communication between Regulation and encoder expansion card in slot 2 (Advanced version only).
Solution: Check that it has been inserted correctly, see Appendix section A.1 on ADL300 QS manual (code 1S9QSEN). Advanced version only.
20 Opt Enc fault [OPTE]
Condition: Error in the communication between Regulation and Encoder feedback card (Advanced version only).
Solution: Check that it has been inserted correctly, see Appendix section A.1 on ADL300 QS manual (code 1S9QSEN).
21 External fault [EF]
Condition: External alarm present.
A digital input has been programmed as an external alarm, but the +24V voltage is not available on the terminal.
Solution: Check that the terminal screws are tight
22 Speed fbk loss [SFL]
Condition: Speed feedback loss alarm.
The encoder is not connected, not connected properly or not powered: verify encoder operation by selecting the PAR 260 Motor speed parameter in the
MONITOR menu.
See parameter 2172 SpdFbkLoss code (on ADL300 QS manual) for information about the cause of the alarm and chapter 10.2 Speed fbk loss [22] alarm
23 Overspeed [OS]
Condition: Motor overspeed alarm. The motor speed exceeds the limits set in the PAR 4540 parameter.
- Limit the speed reference.
- Check that the motor is not driven in overspeed during rotation.
24 Speed ref loss [SRL]
Condition: Speed reference loss alarm; occurs if the difference between the speed regulator reference and the actual motor speed is more than
100 rpm. This condition occurs because the drive is in the current limit condition. It is only available in the Flux Vect OL and Flux Vect CL mode (see PAR
4550).
Solution: Check that the load is not excessive.
25 Not Used
26 Power down [PRR]
Condition: The drive was enabled with no supply voltage at the power section.
Solution: Emergency stop alarm. The Stop key on the keypad was pressed with the Stop key mode parameter set to EmgStop&Alarm in case of
Remote->Terminal Strip or Remote->Digital or Local->Terminal Strip mode.
27 Phaseloss out [PHLO]
Condition: Output phase loss.
Solution: Check Drive/motor connection.
28 OV safety [OVSF]
Condition: Safety status alarm caused by Overvoltage situations.
Solution: the firmware attemps to reset the card automatically.
If the condition is removed (the alarm cleared message is displayed) the alarm can be reset and the drive restarted by deactivating and reactivating Enable
and Start.
29
Safety failure
[SF]
Condition: The state of the "safety function" is communicated to the regulation card via 2 digital inputs: SAFETY_ON (pin P1.8) and SAFETY_EN (pin
P1.9)
Solution: Switch the drive off and then back on. If the error persists, contact the technical service centre.
30
Mot phase loss [MOTL]
Condition: Output phase loss.
Solution: Check Drive/motor connection.
31
Rope change [ROPC]
This may occur in two conditions:
•
the drive continues to run but the rope usage threshold set in parameter 3404 Ropes change thr has been reached;
•
the drive finishes the current travel and then locks because parameter 3414 Direction counter has reached 0 (corresponding to parameter
3412 Ropes usage = 100%).
