
Group 31: Automatic reset
This group defines conditions for automatic resets. An automatic reset occurs after a
particular fault is detected. The drive holds for a set delay time, then automatically
restarts. You can limit the number of resets in a specified time period, and you can set
up automatic resets for a variety of faults.
3023
WIRING FAULT
0, 1 1 1
Selects how the drive reacts when incorrect input power and motor cable connection
is detected (ie, the input power cable is connected to the motor connection of the
drive).
0 = DISABLE – No action.
1 = ENABLE – The drive trips on fault
0035 OUTP WIRING .
3027 OPTION COM LOSS 0, 1 1 1
Selects how the drive reacts when the MREL-01 output relay module is removed from
the drive, and parameters
1402 RELAY OUTPUT 2 , 1403 RELAY OUTPUT 3 or 1410
RELAY OUTPUT 4 have non-zero values.
0 = DISABLE – Prevents the fault 1006 PAR EXT RO even when MREL-01 is
disconnected.
1 = ENABLE – MREL-01 is constantly monitored for disconnection. The drive trips on
fault 1006 PAR EXT RO if external relay outputs are configured for use.
Group 31: Automatic reset
Code Description Range Resolution Default S
3101 NUMBER OF
TRIALS 0…5 1 5
Sets the number of allowed automatic resets within a trial period defined by parameter
3102 TRIAL TIME .
• If the number of automatic resets
exceeds this limit (within the trial
time), the drive prevents additional
automatic resets and remains
stopped.
• Starting then requires a successful
reset performed from the control panel or from a source selected by parameter
1604 FAULT RESET SEL .
Example: Three faults have occurred in the trial time. The last is reset only if the value
for parameter 3101 NUMBER OF TRIALS is 3 or more.
3102 TRIAL TIME 1.0 … 600.0 s 0.1 s 30.0 s
Sets the time period used for counting and limiting the number of resets.
• See parameter
3101 NUMBER OF TRIALS .
3103
DELAY TIME
0.0 … 120.0 s 0.1 s 0.0 s
Sets the delay time between a fault detection and attempted drive restart.
• If DELAY TIME = zero, the drive resets immediately.
