What to do if gefran AGy-EV Inverter shows a drive alarm condition?
If your Gefran Inverter is showing a drive alarm condition, you can acknowledge the active alarm by pressing the Prg button on the keypad. To resume drive operation, you will need to perform an alarm reset command.
How to reset alarm on gefran Inverter?
You can reset the alarm on your Gefran Inverter in several ways: 1. By Keypad: Press the Up and Down keys simultaneously. The reset will occur when you release the buttons. 2. By Digital Input: Use a programmable digital input set as "[5] Alarm reset," which is factory set to Digital Input 5 (terminal 7). 3. By Autoreset function: Configure the P.380, P.381, P.382 and P.383 parameters to enable automatic reset of certain drive alarms.
What to do if I see kbg fw mismatch on gefran AGy-EV?
To resolve a KBG FW mismatch on your Gefran Inverter, use the E@syDrives configurator to upgrade the firmware of the alphanumeric display.
