5.1 Introduction
DA1 Variable Frequency Drives 11/16 MN04020005Z-EN www.eaton.com 141
OVt-F 26 Device output fault
• Please contact your nearest Eaton sales branch.
Sto-F
29 Internal STO circuit fault
• Please contact your nearest Eaton sales branch.
Enc-01
30 No communication between the encoder module and the variable frequency
drive.
• Check to make sure that the module is correctly plugged in and secured.
Enc-02
SP-Err
31 The calculated motor speed is different from the measured motor speed.
• Check the encoder connection, including the corresponding shielding.
• Increase the value of P6-07 if necessary.
Enc-03 32 The motor speed and the PPR value entered in P6-06 do not match. The PPR
value in P6-06 must be at least 60.
• Check the speed entered in P1-10.
Enc-04 33 Channel A fault:
Usually a bad connection.
• Check wiring.
Enc-05
34 Channel B fault
Usually a bad connection.
• Check wiring.
Enc-06 35 Error on channels A and B
Usually a bad connection.
• Check wiring.
AtF-01 40 Motor identification failed:
The measured stator resistance varies between the phases.
• Make sure that the motor is connected properly and working correctly.
• Check the motor windings to make sure they have the same resistance
values.
AtF-02
41 Motor identification failed:
The measured stator resistance is too large.
• Make sure that the motor is connected properly and working correctly.
• Check to make sure that the device’s rated output matches the motor’s
rated output. The difference should not exceed one full output class.
AtF-03 42 Motor identification failed:
The measured motor inductance is too low.
• Make sure that the motor is connected properly and working correctly.
AtF-04
43 Motor identification failed:
The measured motor inductance is too high.
• Make sure that the motor is connected properly and working correctly.
• Check to make sure that the device’s rated output matches the motor’s
rated output. The difference should not exceed one full output class.
AtF-05 44 Motor identification failed:
The measured motor parameters do not match.
• Make sure that the motor is connected properly and working correctly.
• Check to make sure that the device’s rated output matches the motor’s
rated output. The difference should not exceed one full output class.
OVt-Ph
49 A phase in the motor cable is not connected or has a discontinuity.
Sc-FO1 50 No valid Modbus frame was received within the time specified in P5-06.
• Check to make sure that the network master is working correctly.
• Check connecting cables.
• Increase the value of P5-06 to an acceptable value.
