Fault auto-reset function and fault relay action (F20.18 - F20.20)
Auto reset function enables HD3N to reset the fault as per the reset times and interval.
During the reset interval, HD3N stops output and it will automatically restarts if running command is
valid.
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: Wrong parameter setting
E0014: Current detection fault
E0024: External fault
Ref. code
Function Description
Setting Range [Default]
F20.18
Fault auto reset times
0 - 100 [0]
F20.19
Fault auto reset interval
0.01 - 200.00 [5.00s/time]
When F20.18 = 0, it means “auto reset” is unused and the protective device will be activated.
•
If no other fault is detected within 5 minutes, the auto reset count will be automatically cleared.
•
On condition of external fault reset, auto reset count will be cleared.
F20.20
Faulty relay action
00 - 11 [00]
Unit: In auto reset process
•
0: Faulty relay doesn’t act.
•
1: Faulty relay acts.
Ten: In undervoltage process
•
0: Faulty relay doesn’t act.
•
1: Faulty relay acts.
Note: relay must be set as No. 31 function.
