PID reference and feedback loss fault (F20.12
F20.17)
No. Name Description Range
factory setting
F20.12 PID reference lose detected value 0
100%
0%
PID reference loss detection time
F20.12 value is a percentage of the maximum reference source.
If the PID reference value is lower than the detected value (F20.12) in the detection time（F20.13）, the
inverter will implement PID reference loss alarm (E0025).
• When F20.12 or F20.13 is set to 0, the inverter will not detect PID reference loss fault.
PID feedback loss detected value
F20.15 PID feedback loss detection time 0.0
10.0s
0.20
F20.14 value is a percentage of the maximum feedback source.
If the PID feedback value is lower than the detected value (F20.14) in the detection time (F20.15), the
inverter will implement PID feedback loss alarm (E0026).
• When F20.14 or F20.15 is set to 0, the inverter will not detect PID feedback loss fault.
Fault at PID feedback value out of the limit (F20.16
F20.17)
F20.16 Detection value at PID feedback out of the limit 0
100%
100%
F20.17 Detection time at PID feedback out of the limit 0.00
10.00s
0.20
F20.16 value is a percentage of the maximum feedback source.
If the PID feedback value exceed the detection value (F20.16) in the detection time (F20.17), the
inverter will alarm PID feedback out of limiting (E0027).
• When F20.16 or F20.17 is set to 0, the inverter will not detect PID feedback out of limiting fault.
Faulted auto reset function and faulted relay action (F20.18
F20.20)
Auto reset function enables the inverter to reset the fault as per the preset times (F20.18)
interval (F20.19).
During the reset interval, the inverter stops output and it will automa
tically restarts with flying start
mode.
The following faults do not have the auto reset function:
E0008: Power modular fault E0021: Control board EEPROM read/write fault
E0010: Braking unit fault E0023: Parameter setting fault
E0013: Contactor isn’t closed at power on E0024: Peripheral device fault
E0014: Current detection circuit fault
No. Name Description Range
factory setting
F20.19 Auto reset interval 2.0
20.0s/times
5.0
When F20.19 = 0, it means “auto reset” is disabled and the protective device will be activated in case
of fault.
• If no other fault is detected within 5 minutes, the auto reset times will be automatically cleared.
• On condition of external fault reset, auto reset time will be cleared.
