DA1 Variable Frequency Drives 08/18 MN04020005Z-EN www.eaton.com
Possible cause and remedy
Over-temperature at heat sink. The drive is too hot.
The heat sink temperature can be viewed by using P0-21. P0-38 contains an
error register with the last values before the unit was switched off (scan time:
30 s).
• Check to make sure that the variable frequency drive is being operated
within the ambient temperature range specified for it.
(IP20 devices: max. 50 °C; IP66 devices: max. 40 °C).
• Check to make sure that the device fan is running.
• Make sure that cooling air can circulate freely (clearances to neighboring
devices above and below the variable frequency drive).
• Improve the ventilation in the control cabinet if necessary: The ventilation
vent on the device must not be blocked, e.g., by dirt or due to devices being
installed too closely together.
• Reduce the switching frequency with P2-24.
• If possible reduce the load.
Under-temperature
The message will appear if the ambient temperature falls below -10 °C.
In order to be able to start the drive, the temperature must be higher than this.
The parameters' default settings have been loaded.
• Press the STOP button: The drive can then be reconfigured:
External fault (at digital input 5, terminal 10, if P1-13 = 6/7/16/17).
There must be a high-level signal at this input in order to be able to run the
variable frequency drive.
• If a thermistor is connected to terminal 10, check whether the motor is too
hot.
Communication fault with an external operating unit or with a PC.
• Check connections.
Excessively high ripple on DC link voltage
The DC link voltage ripple can be viewed using P0-16.
P0 contains an error register with the last values before the unit was switched
off -37 (scan time: 20 ms).
• Check to make sure that all the mains supply phases are present and that
their voltage balance falls within the permissible tolerance range (3 %).
• If possible reduce the load.
• If the fault persists, please contact your nearest Eaton sales branch.
Incoming power phase failure (only for devices with a three-phase power
supply)
Overcurrent at output
• See Error no. 03.
Malfunctioning heat sink thermistor.
• Please contact your nearest Eaton sales branch.
Error in internal memory. The parameters have not been saved and the default
settings have been loaded.
• Change the parameter values (again) and save them once more.
• If the message appears again, please contact your nearest Eaton sales
branch.
The analog input's input current does not fall within the specified range.
• Check the setting in P2-30 for AI1 (terminal 6) and P2-33 for AI2
(terminal 10).
• In the case of 4-20mA: Check setpoint value connection for wire breakage.
Error in internal memory. The parameters have not been saved and the default
settings have been loaded.
• Change the parameter values (again) and save them once more.
• If the message appears again, please contact your nearest Eaton sales
branch.
