Fault at PID feedback value out of the limit (F20.16 - F20.17)
Ref. Code
Name Description
Setting Range [Default]
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 - 10.00 [0.20s]
F20.16 value is a percentage of the max. feedback source.
If the PID feedback value > F20.16 in the detection time (F20.17), HD31 will alarm E0027 fault (PID feedback
out of limit).
•
F20.16=100 or F20.17=0, HD31 will not detect PID feedback out of limit fault.
Fault auto reset function and faulted relay action (F20.18 - F20.20)
Auto reset function enables HD31 to reset the fault as per the reset times and interval.
During the reset interval, HD31 stops output and it will automatically restarts with speed tracking
mode.
The following faults do not have the auto reset function:
E0008: Power module fault
E0021: Read / Write fault of control board EEPROM
E0010: Braking unit fault
E0023: Parameter setting fault
E0013: Soft start contactor failed
E0024: Peripheral device fault
E0014: Current detection fault
Ref. Code
Name Description
Setting Range [Default]
F20.18
Auto reset times
0 - 100 [0]
F20.19
Auto reset interval
2.0 - 20.0 [5.0s/times]
F20.18 = 0, it means “auto reset” is disabled and the fault protection will be activated.
•
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.
F20.20 Faulty
relay
action
00 - 11 [00]
Units: In auto reset process
0: Faulty relay doesn’t act.
1: Faulty relay acts.
Tens: In the undervoltage process
0: Faulty relay doesn’t act.
1: Faulty relay acts.
Note: Relay needs to be set as No. 31 function (inverter fault).
