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.
Code Description
3101 NR OF TRIALS
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
Sets the time period used for counting and limiting the number of resets.
• See 3101
NR OF TRIALS.
3103 DELAY TIME
Sets the delay time between a fault detection and attempted drive restart.
•If
DELAY TIME = zero, the drive resets immediately.
3104 AR OVERCURRENT
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
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
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
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 FAULT
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.
