Appendix C: Model 2090 Error Code Reference Model 2090 Multi-Device Controller
E009 Encoder Failure
This error indicates that the Model 2090 has detected
behavior indicative of an encoder problem. These
behaviors include large jumps in reported position and
intermittent small reverses in direction (below the
ms
cal
control/interface board, or an electrical noise problem
introducing stray signals onto the encoder lines
(typically due to faulty grounding between the encoder
and control box).
Moving Wrong Direction threshold). These proble
could be caused by a failing encoder, bad electri
connections between the encoder and the
E010 Trigger Failure
This error indicates that the Model 2090 has detected an
overflow in the trigger queue register.
E011 Overheat Error
This error indicates that the Model 2090 has detected
that either the motor or control board has exceeded the
corresponding maximum temperature. This could be
due to environmental factors or excess mechanical drag
on the system. Check what the current temperature is
for both the motor and control board displayed in the
2090 parameter list and contact customer service.
E012 Relay Failure
This error indicates that the Model 2090 has detected the
motor drive relays are not switching properly. This error
will usually occur in combination with an E002 motor
not moving error. Contact customer service to
determine the cause of this error.

Device Offline
This indicates that the Model 2090 cannot find a device
to communicate with over the associated device
interface. Refer to
E007 above for diagnostic
suggestions.
