Issue:
Preventing the ATV320 from going into Reverse.

Product line:
Altivar 320, ATV320

Environment:
all

Cause:
Drive is going into reverse but the machine cannot be allowed to operate in reverse.

Resolution:
Yes, the ATV320 has a Reverse Inhibit parameter RIN, found under the CTL- menu.  The factory setting is no.

Verify that the Reverse command is unassigned.  Under the I_O- menu go to RRS and change to No.

Reverse Inhibition Notes:

Inhibition of movement in reverse direction, does not apply to direction requests sent by logic inputs.

Reverse direction requests sent by logic inputs are taken into account.

Reverse direction requests sent by the graphic display terminal are not taken into account.

Reverse direction requests sent by the fieldbus are not taken into account.

Any reverse speed reference originating from the PID, summing input, etc., is interpreted as a zero reference (0 Hz).
