WX9 ASD Installation and Operation Manual
Trips/Faults
If a user setting or a
WX9 ASD
parameter has been exceeded, or if a data transfer function produces an
unexpected result, a condition that is referred to as a
Fault
is incurred. A
Trip
is a
WX9 ASD
response to
a
Fault
(though
Fault
and
Trip
are sometimes used interchangeably). A
Trip
is a safety feature that
disables the ASD system in the event that a subsystem of the ASD is malfunctioning or a parameter
setting has been exceeded.
are the
Faults
that may result in a
Trip
and the possible causes. When a
Trip
is
incurred, the system displays the
Fault
screen. The
Fault
screen identifies the active
Fault
.
Note:
An improper WX9 ASD setup may cause some trips — reset the ASD to the factory
default settings before pursuing a systemic malfunction (Program
Utilities
Type
Reset
Reset to Factory Settings
).

Possible Causes/Troubleshooting
E
Emergency Off
• Output signal from the ASD is terminated and a brake may be applied if so configured.
• Emergency Off command was received via EOI or remotely.
E-10
Sink/Source
Setting Error
• Improperly positioned
Sink/Source
jumper on the control board or on an option device.
•
Sink/Source
configuration is incorrect.
E-11
Brake Sequence
Response Error
•
is set to a non-zero value.
• Braking sequence discrete input and output terminals are not set up properly.
E-12
Encoder Signal-
Loss Error
• Encoder signal missing while running during closed-loop operation.
• Disconnection at the Encoder circuit.
• Motor is stopped and is generating torque via torque limit control.
• ASD is not configured properly.
E-13
Speed Error
• Result of a motor speed that is greater than the commanded speed when using an encoder
for speed control.
• Improper encoder connection or setup information.
• Defective encoder.
E-17
Key Failure
• Same key input for 20 seconds or more.
e-18
Analog (Terminal)
Input Loss
• VI/II signal loss.
• Terminal Board failure.
• P24 over-current condition.
E-19
CPU Comm. Error
• CPU data Transmit/Receive error.
Note:
The event that caused the Trip(s) must be corrected or the monitored value must decrease to less than the
threshold value required to cause the Trip to allow for a Reset to be recognized. In the event of multiple
active Trips, the Trip displayed will remain until all Faults are corrected and all Trips are cleared.
