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.
Encoder Hardware
If any pair of complementary 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 .2 revs). With PowerTools Pro you can change the Following Error
Limit value on disable in 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 Control Techniques for service advice.
