Issue: 
ATV320 (and most other ATV drives) is not working with a remote mounted keypad.  Keypad shows "Connection in Progress"

Product Line:
Altivar Machine (320 and 340)
Altivar Process (600 and 900)
Altivar 61/71
Altivar 212
Altivar 480 softstart

Environment:
Using remote mounted keypad/display

Cause:
Communication issue between drive and keypad.
Incorrect port settings (remote keypads only support 19200 baud and 8E1 format)

Resolution:
Verify baudrate and format of the ModBus port used for the keypad are set to 19200 baud and 8E1 (8 bits, Even parity, 1 stop bit).
Cycle power to the drive if these settings are changed.

If settings are correct, then review cable routing and connections between drive and keypad. 
Communication cables routed near power wiring will be susceptible to electrical noise which can disrupt communication.
