Cause |
Solution |
|---|---|
|
The mains voltage is too low. |
Verify and correct if necessary the mains voltage (see technical data). |
|
The power supply has detected an error and the Ready signal is switched off. The motor has run on until the DC bus voltage has decreased too far. |
Remove error in the power supply. |
|
The DC bus was overloaded. |
oRun motors with reduced acceleration. oAdapt motion profiles. |
NOTE: The braking resistor is controlled also after an undervoltage error detected in the power supply unit.
This can be necessary if too much energy is supplied in the DC bus because the motors slow down on a mains power outage.
NOTE: After this diagnostic message has been triggered, the braking resistor (bleeder) is switched to the precharge function.
This is why it is not possible to extract feed in energy from the drive via the braking resistor. The braking resistor can only be used to decrease feed back energy after a successful precharge
Refer to parameter InternalDeviceState, 16#89 | 137: Wait until bleeder resistor is ready for the precharge.
