11.1.141 Fault 66 - Klixon
Cause
A klixon type temperature sensor has exceeded the triggering limit.
Troubleshooting
Check for the reason for the temperature trip where the klixon sensor is located.
11.1.142 Fault 70 - Active filter fault
Cause
Fault triggered by digital input (see param. P2.2.7.33).
It is possible to set different responses in the application for this fault. See parameter group Protections.
Troubleshooting
Remove fault situation on active filter.
11.1.143 Fault 74 - Follower fault
Cause
When using normal Master Follower function this fault code is given if one or more follower drives trips to fault.
Troubleshooting
Correct the fault cause on follower and reset fault.
11.1.144 Fault 85 - Baseline Run
Cause
There was a failure during the baseline run.
Troubleshooting
Check parameters in the baseline run settings.
11.1.145 Fault 86 - Condition-based Monitoring, Subcode A1 - Motor Stator Winding Current Fault
Cause
Current unbalance has exceeded the detection high limit.
Troubleshooting
Check motor stator windings.
11.1.146 Fault 86 - Condition-based Monitoring, Subcode A2 - Motor Stator Winding Voltage Fault
Cause
Voltage unbalance has exceeded the detection high limit.
Troubleshooting
Check motor stator windings.
11.1.147 Fault 86 - Condition-based Monitoring, Subcode A3 - Motor Stator Winding Current Warn-
ing S2
Cause
