Setting the drive parameters
Check the settings of the drive parameters against the recommendations below. This is
not the complete list of settings, just settings for the common DC system to work
effectively. The list is valid for the ACS880 primary control program.
• Recommendation: Set parameter 99.04 Motor ctrl mode to DTC in all drives.
• Set parameter 30.26 Power motoring limit to the maximum motoring power of the drive
load cycle.
• Set parameter 30.27 Power generating limit to the maximum generating power of the
drive load cycle.
• When you use a brake chopper:
• Set parameter 30.30 Overvoltage control to Disable in all drives.
• Set parameter 43.06 Brake chopper to Enabled with thermal model or Enabled
without thermal model in those drives that you use the chopper.
• Set parameter 31.23 to No action in all drives to prevent unnecessary fault trips.
