0xCD
PWM Input 28 Out of Range
PWM_Input_28_Out_of_Range
0x210C
Fault Type(s):
1 = The input is disconnected.
2 = The measured input
frequency is below the
(PWM_Input_28_Low_
Frequency) – (PWM_
Input_28_Frequency_
Fault_Tolerance).
3 = The measured input
frequency is above the (PWM_
Input_28_High_Frequency) +
(PWM_Input_28_Frequency_
Fault_Tolerance).
4 = The measured duty cycle
is below set limits, (PWM_
Input_28_Low_Duty_Cycle)
– (PWM_Input_28_Duty_
Cycle_Fault_Tolerance).
5 = The measured duty cycle
is above set limits, (PWM_
Input_28_High_Duty_Cycle)
+ (PWM_Input_28_Duty_
Cycle_Fault_Tolerance).
1. This fault diagnostic execution
cycles every 4msec. The input
is considered disconnected if no
PWM signal occurs for 16msec or
the measurements are not updated
every 16msec.
2. Mistuned parameters.
3. Faulty wiring.
Set: The input frequency and/or
duty-cycle on Input 28 exceeds
the congured limits set by
PWM_Input_28_x_Duty_Cycle
and PWM_Input_28_x_
Frequency, where x = {Low,
High}.
Clear: Reset Controller.
Fault Action:
None, unless a fault action
is programmed in VCL.

Lift Input Fault
Lift_Input
0x2104
Fault Type(s): 1
The associated fault diagnostic with
the assigned lift-input source triggers
this fault.
For example:
If the Lift_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 “Lift_Input_Source”
are cascaded and reported.
Clear: Resolve any input
assignment conict, or out of-
range faults, then
Reset Controller.

Fault Type(s):

Set: The difference between
the commanded phase PWM
duty cycle and the measured is
greater than allowed.
