Issue
What would cause the ATV630 drive not to follow the analog speed reference and ramp up to speed?

Product Line:
ATV630, ATV930, ATV660, ATV960, ATV680

Environment:
All 

Cause:
Missing analog signal for speed control 

Resolution:
  • Check to see if the drive is seeing the analog input signal in the IO map monitoring menu [Complete settings] [Input/Output] [AI/AQ] (Menu 5.11, AI/AQ tab). Also make sure the analog type is assigned correctly per the signal (0-10V or 4-20mA) that you're using. And that the Min and Max values are set properly according to the range that your signal is using. 
  • Check to see if there is a preset speed assigned that is overriding the analog signal. [Complete settings] [Generic functions] [Preset speeds]
  • Check to see if there is an auto manual or reference switching assigned. (This parameter can be accessed if [PID Feedback] PIF is not set to [Not Configured] NO.) If so, check the digital input to see if the input is switching for the correct analog input. 
  • Make sure the drive's status on the HMI is showing the status as 'Run' (upper left-hand corner of the display).
  • Check to see if the drive's status is 'CLI', which means the motor is pulling excessive amps and the drive is in current limit mode (upper left-hand corner of the display).
