Video: How Do I Configure an ATV320 Drive for 2-Wire Control?

Follow these steps to configure the drive for 2-wire control:

1. From the main menu, navigate to: CONF → FULL → I/O (I_O-)
2. Locate the TCC parameter.
3. Set TCC = 2C to enable 2-wire control.

Selecting the 2-Wire Control Type

After enabling 2-wire control, choose the desired operating mode using the TCT parameter:

• TRN (Transition Mode) - Default setting
• LEL (Level Mode)

Operating Modes

Transition Mode (TRN)

• The drive must be powered on before a run command is issued.
• A transition of the run signal is required to start the drive.
• Recommended for most applications.

Level Mode (LEL)

• The run command can remain active while the drive is powered off.
• When power is restored, the drive will start automatically if the run command is present.
• If no run command is present, the drive will remain in RDY (Ready) status until a run command is received.

Warning: Level Mode (LEL) may cause the drive to start automatically after a power cycle. Ensure this behavior is safe and appropriate for your application before enabling it.
