Siemens 300859 - Axis drive generator mode: response voltage > monitoring
Axis drive generator mode: response voltage > monitoring
The value in MD 1631: $MD_LINK_VOLTAGE_GEN_ON (response voltage for generator axis) is greater than MD1630: $MD_LINK_VOLTAGE_MON_THRESHOLD (response threshold for DC link monitoring) Control reaction: Interface signals are set. Alarm display.
Safety
- Drive/power/encoder circuit: hazardous voltages may remain in the DC link after power-off. Lock out / tag out, wait for discharge per the drive documentation, and use qualified personnel only.
Common Causes
- The value in MD 1631: $MD_LINK_VOLTAGE_GEN_ON (response voltage for generator axis) is greater than MD1630: $MD_LINK_VOLTAGE_MON_THRESHOLD (response threshold for DC link monitoring)
Troubleshooting Steps
- 1Please inform the authorized personnel/service department.
- 2Modify MD 1631: $MD_LINK_VOLTAGE_GEN_ON (response voltage for generator axis) or - Modify MD 1630: $MD_LINK_VOLTAGE_MON_THRESHOLD (response threshold for DC link monitoring).
- 3Alarm display showing cause of alarm disappears. No further operator action necessary
