This FAQ applies only to the MICROMASTER 4 Advanced Operator Panel (AOP).

What is the cause of the AOP message "No Drive Responding"?

This means the AOP is attempting to connect to the drive, but it is not responding to the USS commands.

  1. Set mode to "Internal"
  2. Select "Parameters"
  3. Select the AOP Parameter Set
  4. View "All" parameters
  5. parameterization as follows:
    P0003 = 3
    P8552 = 0    Base Slave Address
    P8553 = 6    Default Baudrate
    P8554 = 0    Autobaud
