Possible cause and remedy
The customer's settings for the parameters have been imported.
• Press the STOP button.
Motor PTC thermistor over-temperature
The device's internal fan is experiencing a fault
For frame size FS8: Incorrect rotation direction of the device fan
• Check the supply voltage phase sequence (L1–L2–L3).
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 load.
Maximum permissible torque exceeded.
• If possible: Reduce the load or increase acceleration time t-acc.
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.
Device output fault
• Please contact your nearest Eaton sales branch.
Internal STO circuit fault
• Please contact your nearest Eaton sales branch.
No communication between the encoder module and the variable frequency
drive.
• Check to make sure that the module is correctly plugged in and secured.
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.
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.
Channel A fault:
Usually a bad connection.
• Check wiring.
Channel B fault
Usually a bad connection.
• Check wiring.
Error on channels A and B
Usually a bad connection.
• Check wiring.
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.
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.
