5 Fault messages
5.1 Introduction
140 DA1 Variable Frequency Drives 11/16 MN04020005Z-EN www.eaton.com
E-trip 11 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.
SC-ObS
12 Communication fault with an external operating unit or with a PC.
• Check connections.
F
(t-dc 13 Excessively high DC link voltage ripple
The DC link voltage ripple can be viewed using P0-16.
P0-37 contains a fault register with the last values before the unit was
switched off (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%).
• Reduce the load if possible.
• If the fault persists, please contact your nearest Eaton sales branch.
P-LOss
14 Incoming power phase failure (only for devices with a three-phase power
supply)
h O-I
15 Overcurrent at output
• See Error no. 03.
th-f
(t 16 Malfunctioning heat sink thermistor.
• Please contact your nearest Eaton sales branch.
dAtA-F
17 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.
4-20 F
18 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 4-20 mA: Check the setpoint connection for wire breakage.
dAtA-E
19 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.
V-dEf
20 The customer’s settings for the parameters have been imported.
• Press the STOP button.
F-Ptc
21 Motor PTC thermistor over temperature
FAn-F
22 The device’s internal fan is experiencing a fault
In the case of frame size FS8: Wrong device fan operating direction
• Check the supply voltage phase sequence (L1–L2–L3).
O-hEAt 23 The measured ambient temperature exceeds the specified value.
• Check the device’s internal fan.
• Make sure that the required clearance around the device is being
maintained and that cooling air can flow through the vents on the device
unimpeded.
• Reduce the switching frequency with P2-24.
• If possible: Reduce the load.
O-torq
24 Maximum permissible torque exceeded.
• If possible: Reduce the load or increase acceleration time t-acc.
V-torq
25 Only active if brake control is enabled in hoisting gear mode (P2-18 = 8). The
torque produced before the hoisting gear’s mechanical brake is enabled falls
below the set threshold.
