Parameters
Group 31: Automatic Reset
This group denes 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 specied time period and set up automatic resets for a variety of faults.
Table 17: 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 dened 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.

3103 DELAY TIME
