DC link voltage not adjustable

 

 

Problem

The DC link voltage cannot be set.

Remedy
  1. Check digital input "DI 00".
    • The configuration of the digital inputs/digital outputs can be viewed in the configuration of the device in the "Inputs/outputs" configuration menu in the "Basic device" submenu. Digital input "DI 00" is normally assigned "FCB 51 Output stage inhibit". If this input is not wired externally, "No function" must be assigned to the digital input.
  2. Check whether application limits are configured in the device.
    • The configuration of the application limits can be viewed in the configuration of the device in the "Monitoring functions" configuration menu in the "Limit values" submenu. The default for application limits is "0".
  3. Check whether the operating range of the "State of charge control" operating mode is configured.
    • The configuration of the operating range can be viewed in the configuration of the software module in the "Operating modes" configuration menu in the "State of charge control" submenu. The default value for the operating range is "0".
