Parameters
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 set up
automatic resets for a variety of faults.
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 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
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 3101
NUMBER 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 (DISABLE)
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 (
ENABLE)
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 (
ENABLE)
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 UNDERVOLT) after the delay set by 3103 DELAY TIME, and the drive resumes
normal operation.
3107 AR AI<MIN 0, 1 1 1 (
ENABLE)
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.
