Why is my ATV630 drive not following the analog speed reference or ramping to speed?

1.- Verify the Analog Signal

• Go to I/O Map (4.10) → Analog Inputs Image.
• Confirm the drive is receiving the expected signal.
  • Example: If 10V is sent to AI1, the display should show ~10V.

2.- Check Analog Input Configuration

• Navigate to:
  Complete Settings → Input/Output → AI/AQ (Menu 5.11)
• Ensure:
  • Input type matches your signal (e.g., 0–10V or 4–20 mA).
  • Minimum and maximum values are set correctly.

3.- Confirm Reference Switching (if used)

• Check the Digital Input Map.
• Ensure the correct digital input activates the intended reference.
  • Example: If using a Hand/Off/Auto switch on DI3:
    • Verify DI3 changes state when switching modes.
    • Measure ~24 VDC between DI3 and COM when active.

4.- Check for Preset Speed Override

• Navigate to:
  Complete Settings → Generic Functions → Preset Speeds
• Ensure no preset speed is overriding the analog reference.

5.- Review Auto/Manual or PID Reference Settings

• If configured, confirm the correct input is selected for speed reference.
• Verify associated digital inputs are switching properly.

6.- Verify Drive Status

• Ensure the drive displays “Run” on the HMI.
• Check for “CLI” (Current Limit) status:
  • Indicates the motor is drawing excessive current, preventing normal ramp-up.
