Why Danfoss VLT Safety Option MCB 152 show External error: Safe field-bus telegram mismatch?
If your Danfoss DC drive displays the 'External error: Safe field-bus telegram mismatch' error, it means the safe fieldbus telegram is invalid. To resolve this, check the telegram format settings in both the fail-safe PLC and the safety option.
What to do if Danfoss VLT Safety Option MCB 152 show External error: Safe field-bus destination address mismatch?
If you encounter the 'External error: Safe field-bus destination address mismatch' error on your Danfoss DC drive, it indicates that the destination address on the safe fieldbus is invalid. Ensure that the addresses on the PLC and the safety option match to correct this issue.
What to do if Danfoss VLT Safety Option MCB 152 DC Drives show Internal error: Fail-safe data CRC mismatch?
If your Danfoss DC drive displays the error 'Internal error: Fail-safe data CRC mismatch', this means the CRC of the safety option does not match the stored CRC value on the drive. To solve this, configure the safety option with MCT 10 Safe Plug-in or by CRC select/LCP copy.
What to do if Danfoss VLT Safety Option MCB 152 DC Drives show External error DI1?
If your Danfoss DC drive is showing 'External error DI1', it could be due to a safety input connected to DI1 having an illegal signal level, or the sensor might be broken. You can resolve this by checking that the configuration of DI1 (parameter 42-21 Type, sub-index [0]) is set correctly and that the connected sensor is installed according to specification. Additionally, you can extend the discrepancy time for DI1 using the VLT® Motion Control Tool MCT 10 Safe Plug-in.
What to do if Danfoss VLT Safety Option MCB 152 show External error DI2?
If your Danfoss DC drive displays 'External error DI2', this could be caused by a safety input connected to DI2 having an illegal signal level, or the sensor may be broken. To fix this, check that the configuration of DI2 (parameter 42-21 Type, subindex [0]) is set correctly and that the connected sensor is installed according to specification. You might also need to extend the discrepancy time for DI2 using the VLT® Motion Control Tool MCT 10 Safe Plug-in.
What to do if Danfoss VLT Safety Option MCB 152 show Internal error: DI1 in PUST?
If your Danfoss DC drive shows the error 'Internal error: DI1 in PUST', it indicates that the safety input connected to DI1 has illegal signal levels, or the sensor is broken. To resolve this, check that the configuration of DI1 (parameter 42-21 Type, sub-index [0]) is set correctly and that the connected sensor is installed according to specification. You can also extend the discrepancy time on the safe input using the VLT® Motion Control Tool MCT 10 Safe Plug-in.
What to do if Danfoss VLT Safety Option MCB 152 DC Drives show Internal error: DI2 in PUST?
If your Danfoss DC drive displays the error 'Internal error: DI2 in PUST', it means that the safety input connected to DI2 has illegal signal levels, or the sensor is broken. To fix this, check that the configuration of DI2, parameter 42-21 Type, is set correctly or that the connected sensor is installed according to specification. You can also extend the discrepancy time on the safe input using the VLT® Motion Control MCT 10 Safe Plug-in.
