Start-Up
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.
Group 31: Automatic Reset
Code Description Range Resolution Default S
3101 NR OF TRIALS 0…5 1 5
Sets the number of allowed automatic resets within a trial period defined by 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 1604
FAULT RESET SEL
.
Example: Three faults have occurred in the trial time. The last is reset
only if the value for 3101
NR 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 3101
NR OF TRIALS
.
3103 DELAY TIME 0.0…120.0 s 0.1 s 6.0 s
Sets the delay time between a fault detection and attempted drive restart.
• If
DELAY TIME
= zero, the drive resets immediately.
3104 AR OVERCURRENT 0, 1 1 0
Sets the automatic reset for the overcurrent function on or off.
0 =
DISABLE
– Disables automatic reset.
1 =
ENABLE
– Enables automatic reset.
• Automatically resets the fault (
OVERCURRENT
) after the delay set by 3103
DELAY TIME
, and the drive resumes
normal operation.
3105 AR OVERVOLTAGE 0, 1 1 1
Sets the automatic reset for the overvoltage function on or off.
0 =
DISABLE
– Disables automatic reset.
1 =
ENABLE
– Enables automatic reset.
• Automatically resets the fault (
DC OVERVOLT
) after the delay set by 3103
DELAY TIME
, and the drive resumes
normal operation.
3106 AR UNDERVOLTAGE 0, 1 1 1
Sets the automatic reset for the undervoltage function on or off.
0 =
DISABLE
– Disables automatic reset.
1 =
ENABLE
– Enables automatic reset.
• Automatically resets the fault (
DC UNDERVOLTAGE
) after the delay set by 3103
DELAY TIME
, and the drive resumes
normal operation.
3107 AR AI<MIN 0, 1 1 1
Sets the automatic reset for the analog input less than minimum value function on or off.
0 =
DISABLE
– Disables automatic reset.
1 =
ENABLE
– Enables automatic reset.
• Automatically resets the fault (
AI
<
MIN
) after the delay set by 3103
DELAY TIME
, and the drive resumes normal
operation.
Warning! When the analog input signal is restored, the drive may restart, even after a long stop. Make sure
that automatic, long delayed starts will not cause physical injury and/or damage equipment.
3108 AR EXTERNAL FLT 0, 1 1 1
Sets the automatic reset for external faults function on or off.
0 =
DISABLE
– Disables automatic reset.
1 =
ENABLE
– Enables automatic reset.
• Automatically resets the fault (
EXTERNAL FAULT
1 or
EXTERNAL FAULT
2) after the delay set by 3103
DELAY TIME
,
and the drive resumes normal operation.
