Issue:
Looking for the AL05 code shown on the ATV212.

Product Line:
ALTIVAR 212, ATV212

Environment:
All

Cause:
Troubleshooting

Resolution:
AL05 is the alarm code display in case of a signal loss on an analog input.

Example on VIA in 4-20mA
FMOD = VIA
[4-20 mA loss] F644 = freewheel
[Loss of VIA] F633 = 20% --> 20% on F633 is for 4mA.

Start the drive with VIA higher than 4mA
--> The drive run and goes to the speed given by VIA.
If VIA signal is loose (VIA less than 4mA)
--> AL05 is display showing the 4-20mA loss is detected.
--> Then Drive is stopped in freewheel

If AL05 is display on your product :
- check the signal level on VIA
- then check F633 is set correctly

There is nothing in manual on this code.
