FB error: MC_Power. Not allowed value at input PowerDefaultState, while drive is not operational.
Description | The drive is to be switched to operational state using a MC_Power function block. At least one of the Enable... inputs is still assigned FALSE and the drive is not ready for operation. It is now detected that an invalid value was applied to the PowerDefaultState input of the function block.
Response | Class | - | No response, only information as long as at least on Enable_... Input has the value FALSE. If all Enable_... inputs are set to TRUE, the drive is not switched ready for operation. If a permitted value is present at the PowerDefaultState input, the Error output displays FALSE and ErrorID displays no error detection.

If TRUE is assigned to all Enable_... inputs, the drive is switched to operational state at the very moment.

Solution | Class | - | The values at input PowerDefaultState must be of type MCV_DRIVE_POWER_STATE . Please apply one of these values. If the applied value was calculated by the application, check why the value exceeds the allowed range.
Error type | -
