What is the ERR7 fault on Altivar ATV58 keypad display?
 
Product Line:   
ATV58
 
Environment:  
All
 
Cause:  
ERR7
 
Resolution:   
Probable Causes:
Serial link time out error. The keypad display is not getting a response from the drive controller. If the keypad display is remotely mounted, electrical noise may be present. The port baud rate (tbr) may be set to 9600 bits/s.
Corrective Actions:
Cycle power on the drive controller. If the keypad display is remotely mounted, verify that the cable is properly shielded. Ensure that the cable is routed away from motor leads. See below menu 4 control for instructions for resetting the tbr parameter back to 19200 bits/s. If the problem persists, replace the control board on the drive controller with part number VX4A581U. Note: This part is peresently obsolete. An Ini fault may be displayed if the problem persists.
