Epsilon EP-B Base Drive Reference Manual
Encoder State
Certain encoder states and state transitions are invalid and will cause the drive to report an encoder state fault. This is
usually the result of noisy encoder feedback caused by poor shielding. For some types of custom motors it may be
necessary to disable this fault. See Faults view section for more information.
Encoder Hardware
If any pair of encoder lines are in the same state, an encoder line fault is generated. The most likely cause is a missing
or bad encoder connection.
Motor Overtemp
This fault is generated when the motor thermal switch is open due to motor over-temperature or incorrect wiring.
RMS Shunt Power
This fault is generated when RMS shunt power dissipation is greater than the design rating of the internal shunt.
Overspeed
This fault occurs when the actual motor speed exceeds the Overspeed Velocity Limit parameter. This parameter can be
accessed with PowerTools Pro software.
Max Following Error
This fault is generated when the following error exceeds the following error limit (default following error limit is 0.2 revs).
With PowerTools Pro you can change the Following Error Limit value or disable it on the Position view.
Travel Limit +/-
This fault is caused when either the + or - Travel Limit input function is active.
All “On”
This is a normal condition during power up of the drive. It will last for less than 1 second. If this display persists, call
Technical Service at Control Techniques.
