Lower Input Fault
Lower_Input
0x2105
Fault Type(s): 1
The associated fault diagnostic with
the assigned lower-input source
triggers this fault.
For example:
If the Lower_Input_Source is
an analog input, then any faults
detected by the respective Input
fault diagnostics are cascaded and
reported within this fault code.
Note: An analog input fault
diagnostics may be out of range
when set as a voltage input or
may include potentiometer faults if
congured as a 2/3-wire pot.
Set: Faults from the respective/
assigned “Lower_Input_
Source” are cascaded
and reported.
Clear: Resolve any input
assignment conict, or out-of-
range faults, then
Reset Controller.

Hazardous Movement
Hazardous_Movement
0x211C
Fault Type(s):
1 = The motor speed is in the
opposite direction of the
speed request and the
motor fails to accelerate in
the correct direction for a
programmed time. In the
event of a change to neutral,
this hazard will be detected if
the motor fails to accelerate
toward zero speed for a
programmed time.
2 = The acceleration is in the
opposite direction of the
difference between the
operator speed request
and the motor speed. The
speed in the commanded
direction is greater than
the commanded speed by
more than a parameter
(Hazardous_Speed) for
a programmed time
(Hazardous_Throttle_
Response_Time).
(1) Mistuned Hazardous_Direction_
Response_Time parameter.
(2) Mistuned Hazardous_Accel
parameter.
(2) Mistuned Hazardous_Speed_Error
parameter.
(2) Mistuned Hazardous_Throttle_
Response_Time parameter.
Set:
This fault detects hazardous
movement when the motor is
requested to be moving.
The rst hazard is a motor that
is not able to slow down if the
throttle goes to zero or the
direction switch is not in the
direction of travel.
The second hazard is a motor
that accelerates the wrong way
or goes too fast.
Note: This fault only occurs
when the Control Mode Select
is in Speed_Mode, Speed_
Mode_Express, or Servo_Mode.
Clear: Reset Controller.
Setting Hazardous_Direction_
Response_Time = 0 will
disable these checks.
