How Do I Configure an ATV630 or ATV930 Drive for PID Auto/Manual Control Using an HOA Switch?

To configure PID Auto/Manual operation with an HOA switch:

1. Navigate to: [Complete Settings] → [Pump Functions] → [PID Controller] → [Reference Frequency]

2. Configure the PID reference:

   • Set Internal PID Reference = No.
   • The drive will use FR1 as the PID setpoint source.
   • Set FR1 = AI1 (Speed Potentiometer).

3. Configure the Auto/Manual selection:

   • Assign PAU (Auto/Manual Assignment) to a digital input, for example DI3.
   • Set the Manual Reference Assignment to AI1 (Speed Potentiometer).

Operation

Hand (Manual) Mode

• DI3 = High
• The drive speed reference is taken directly from the AI1 potentiometer.
• The drive operates in manual speed control.

Auto Mode

• DI3 = Low
• The drive operates using PID control.
• The PID setpoint is provided by the AI1 potentiometer.
• The drive adjusts output based on PID feedback to maintain the desired process value.
