Flashing E on the display of the ATV21 or ATV212 drive.

The drive is in a faulted status, initiated by one of the following:
1) CMOd is set to 0 or 2, the drive is in remote mode and the keypad STOP button is pressed.  Since the drive is looking for a stop command from a logic input or serial communications, the STOP button is assigned to function as an E-STOP. (See page 87 in the ATV212 Programming Manual and attachment)

2) A logic input is assigned as External Fault, functions 11 or 45, and that logic input fault is activated.
Check the following parameters:
F111 - Terminal F logic input assignment (default = 2; run forward)
F112 - Terminal R logic input assignment (default = 6; preset speed)
F113 - Terminal RES logic input assignment (default = 10; fault reset)

To reset the fault, either cycle power to the drive or activate a logic input that is assign as Fault Reset, functions 10 or 55.
