0xCC
PWM Input 29 Out of Range
PWM_Input_29_Out_of_Range
0x210D
Fault Type(s):
1 = The input is disconnected.
2 = The measured input
frequency is below the
(PWM_Input_29_Low_
Frequency) – (PWM_
Input_29_Frequency_
Fault_Tolerance).
3 = The measured input
frequency is above the
(PWM_Input_29_High_
Frequency) + (PWM_
Input_29_Frequency_
Fault_Tolerance).
4 = The measured duty cycle
is below set limits, (PWM_
Input_29_Low_Duty_Cycle)
– (PWM_Input_29_Duty_
Cycle_Fault_Tolerance).
5 = The measured duty cycle
is above set limits, (PWM_
Input_29_High_Duty_Cycle)
+ (PWM_Input_29_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 29 exceeds
the congured limits set by
PWM_Input_29_x_Duty_Cycle
and PWM_Input_29_x_
Frequency, where x = {Low,
High}.
Clear: Reset Controller.
Fault Action:
None, unless a fault action
is programmed in VCL.
